“Food – The Next Big crisis For Humanity?”

2 Comments

Humans have been living on this planet for many centuries and the prior need for their survival is food, water and a place to live. For these necessities they have been traveling for places and working hard to find them. All these factors are an important part for human survival and a disbalance caused by either of them, can lead humans to a condition of uncertainty and a question to their survival. Humans do need energy so as to perform all their basic day to day activities. These foods provide any individual basic proteins, vitamin, carbohydrates and fibres to remain fit and healthy.Food and its need is the important need for human survival, but with the increase in population tHe need for it has increased but production relative to it is significantly less and the resources we do have, humans hardly care and most if it gets wastage. This is an area of concern especially when we do acknowledge the need for it. 

Food wastage has been an area of concern for humans and humans are quite aware for the same, but still we hardly take any action in reducing it but the main question do arises is that why and where do this Food wastage occur:

  1. The prior places are marriage and various other functions, where Food is prepared in heavy quantities, while people eat less, most of the food gets wasted. 
  2. Hostel, where the taste is the major issue. Since students don’t like the food they consume, it results in wastage. 
  3. People usually prefer to take more food initially, which if it doesn’t taste good, goes in the bin. 
  4. People do not know their ideal eating food quantity. So they usually prefer to take note of it. 
  5. There are various other places and reasons for the wastage of these food resources which surely needs to be addressed and taken care of. 

We do know and discuss that food is an essential part for our life, and we want to save it. But there are hardly any steps taken in these areas. Various NGOs and other organizations as well as government policies are working in order to save this essential resource. But people need to be aware of their approach and their deeds. These organizations and policies would be effective enough if people do perform and do activities on their own so people do need  to:

 

  • Next time approach which would include small quantities initially and if they like it, they can prefer taking it again. 
  • Taste would be the prior thing which needs to be cared for.
  • People must test their eating abilities and the amount they can have at a time. Which surely directs them to be a water of the quantity which best suits them and need to take the same quantity so as to prevent any wastage.
  • More and more awareness must be increased in the places of more wastage and people must be made aware for it to stop.
  • Also the places where the most food is wasted, must be given to people or places where people lack food.

 

So it’s time to understand that this resource is an essential component for our survival and this we need to take the desired steps in order to save these. Any wastage must be prevented and in case food wastage, it must be restored for future use or given to people in need for the same. Future is an era of possibilities and humans would be able to see a better and improved phase of life but it’s only possible if we do have resources to feed them. So we must work together in this area and this will save humanity and save this essential and important resource.

“Automobile – Field For Human Investment”

Technology and it’s advancement has helped humans to make their life more easier and comfortable. All the commodities and facilities have led humans to a phase of ease to life. Automotive or automobile vehicles are one of them. Vehicles be it TWO- Wheelers or Four Wheelers  or airplanes or ships, rickshaws and many more have helped humans to travel around the world and made this world an easy to reach destination at any time. These have not only helped people to acknowledge places around the world, but even interact with people from different cultures and backgrounds.These vehicles help us send things from one place to another,carry heavy loads both men and material from one place to another and even help us feel relaxed while travelling in them. The industrial revolution and its initiation provided a boon to the automobile and aviation industries. But considering the ground vehicle, these have really proven to be beneficial for people and helped them by providing them with ease to work. 

There have been various advances in vehicles and the mode of ignition and power to them. These have been considered so as to bring much more efficiency, speed and cost effectiveness to these models. But we do see till date that these automotive models are not much safer. These have been comfortable and have made life of humans easier but still fail to provide 100% safety for the traveller travelling in it. These models are usually made through materials which do provide strength to structure but are less impact resistant. These models do resist much shock impact but still transfer most of it, which does harm the person in it. Many people lose their life every year in accidents while their automobile fails to provide them security. 

Various companies are bringing up many products and models which are safer and impact resistant but these do cost a lot for individuals.The material we still use in manufacturing these automotive are same as were used in the earlier times. This is due to the lack of companies investment in new material. Also the materials do cost more to the company which directly reduces the profits. While some new materials have been added into manufacturing of different components for these vehicles, the major structure and frame still comprises the similar material. 

Companies should invest in their research and development techniques and new ideas must be initiated and funded by both companies as well as the government so as to bring out the best and impact resistant materials and structure so as to resist any kind of damage and harm to the individual or individuals traveling in it. While the safety in two Wheeler is much less compared to that in a car, but still cars are not completely safe. The rights of customers lies in the fact of providing them type safety along with comfort and ease to operate. 

Travelling has been a part of our life and safety in it is the first priority to be taken care of. While we do invest a lot of investment in adding features to our automotives and different accessories, we should be investing in making those vehicles. More secure. Maybe we can see better alternatives and resources in future which could prove to be much secure and safer for individuals to travel through it. While there is still investment going to shift to flying cars and vehicles, we should be investing much of our resources in making any vehicle secure enough to provide better and secure travel.

“Effectiveness Of Our Sanitizing Tools-Soap Vs Sanitizer”

1 Comment

Health has become an issue of concern especially during the prevailing pandemic of coronavirus. Covid-19 is increasing day by day due to it’s effectiveness of spreading by touch.We know that these viruses do require a host to be effective enough to perform function. But we do see that there is no such effective way out to be free from it. Scientists do believe that the best option to do so is to take precaution and preventive measures to fight this harmful virus. We know that this  virus spreads from person to person through contact or through any medium which helps this virus to be transmitted. The major area of concern for doctors and scientists who are helping us to fight it against this virus is the Mutation possibilities. Mutation are the gene changes in these viruses which occur whenever they replicate to other and future viruses. Their mutations are either due to environmental conditions which do help them to be adaptive to it or due to the complexity of their gene which does get different while transmitting. It is an area of concern since these viruses do mutate and with this mutation going on increasing it may happen that doctors may not be able to know about the virus even if it is present due to the old ways to detect them, this could surely be harmful for patients and this people near us. As we see that this virus is increasing and many people are getting affected by it, the possibility of its mutation also increases. 

But since we know that there is no such vaccine which could prevent and save us from its effect, the better way out is to use preventive measures. This mainly included maintaining a distance of 1-2 metre when we talk or even in the market. Use a mask and wash hands frequently. But the main question which still hits the mind of people is which is better Soap or Sanitizer? Since soap has been a part of human’s life for many centuries, sanitizer has also helped humans to remain clean and healthy. So are these both equally sufficient to fight against this virus or do we have better ways out in them to help us remain safe. 

So in this fight to find out which is better between soap and sanitizer, scientists did some of the experiments to find better results. For this they took bacteria known as E. Coli and rubbed in their hands completely. 

 

  • For the first case they took sanitizer. There were two conditions recorded in it. The first was to rub with a small quantity of sanitizer and record the result and second was to take an amount more than the usual quantity and record the details. 
  • For the second case they took soap. For the first experiment, they washed their hands for about 10 seconds and recorded details while for the second time they washed their hands for about 30 seconds and recorded the details.

 

The outcomes were really worth watching. Considering The first case, a sanitizer of less amount did clean most of the bacteria but a sanitizer with more amount cleaned almost all the bacteria over hands. Soap for about 10 seconds removed bacteria but rubbing for about 30 seconds did remove most of the bacteria as compared to 1st case of rubbing for 10 seconds. But the difference between soap and sanitizer and their comparison, sanitizer was found out to be more effective than soap in their results. Sanitizer was recorded to remove most of the bacteria while there were few left out even washing hands for about 30 seconds.

We do know that sanitizing either with soap or sanitizer both can be effective to be free from virus and bacteria, but sanitizers do have an edge over soap in their capabilities of performance. Washing hands with sanitizers thus can be effective enough to help any individual fight back this virus with other preventive measures also. We know it’s a difficult time and we all need to be aware about the do’s and dont’s and this need to be aware enough to protect ourselves as well as other people in our country and thus bring back everything back to normal and make our country and world better, safe and healthier.

“Underwater lifestyle – Possibilities For Numerous Opportunities?”

Humans have been working hard since the inception of their life so as to make their life easier and comfortable. They have been traveling in the search of better food, water and shelter resources. All these efforts have resulted as the initial steps toward life we acknowledge today. With the latest technologies and gadgets, we humans have brought a wider change in our day to day lifestyle. But with all these coming years, a lot many changes have been seen, with growing population, scarce resources and thus fighting for basic needs. In the search for better life in prevailing problems of increasing population, and less land for providing the basic necessities like homes, hospitals, colleges, dumps for storing waste and a lot more, more and more alternatives are in the run to be opted. But the alternative ways which researchers are very fascinated about is the underwater lifestyle. What if we could breathe underwater . Anything is possible. And if this could have been possible or if this could be possible, it would open up a wide range of possibilities for humanity. 

So if humans could breathe underwater or by technology we can make our gene different and can breathe underwater it would help us:

 

  • Remain underwater for a while and thus research better about the things underneath the water. 
  • Construction would be easier as we do have machines which can operate underwater but not manual workload. This would help us do that.
  • We can discover more resources, hidden underwater and have not been found yet.
  • We would be able to travel underneath.
  • Various other possibilities for increasing population and fulfilling their needs.
  • We could even enjoy swimming with other aquatic living beings, this would bring a different level of excitement.
  • We must also observe these water resources to be clean enough, since humans won’t like living in a polluted environment.

 

It all seems that the possibility for humans to breathe underwater would help humans to find the problem to find space and many others but we humans are not meant to live under water unless we include technology. But if we would have been able to breathe underwater, our life’s would have been different, since aquatic life would have been affected the most and water would also have seemed a lot more crowded. This is the possibility if we would have been able to breathe, but since we cannot breathe, so if we still find alternatives through technology, our bodies’ would respond differently since our body would not not react accordingly. Our bodies would soon get affected and we would suffer hypothermia. Also we would be requiring  spectacles for watching our surroundings, since our eyes cannot afford to watch in it. Also if we would, it would not be a clear view.. 

There would be other difficulties for humans if they went underwater in search of survival. But soon we need to find an alternative for the increasing population and it’s possible that we could shift to water for our survival in future times. This could be possible with all sorts of better technology for betterment of humans and not bothering the prevailing aquatic life. Tomorrow is a world of different possibilities, opportunities and outcomes and humans would definitely find out the better ways to survive and make their life the way it is and the way it should be.

“The Outcomes Of Shifting To Cleaner Fuel Instantly”

We have been hearing from recent times that the problem of Climate Change and Global Warming is increasing and is leading to deteriorate our environment and its resources. Our glaciers have started to melt and air is hardly left cleaner to be breathed. All these factors have also led the life of humans and other animals to suffer. This has been caused due to human early efforts to find themselves the need for power and energy. The major revolution which brought a wider change to the ground reality and people was the initiation of The Industrial Revolution which not only helped people to get jobs and get employed but also helped various families to earn their basic needs and necessities. But with times we have found major sources of energy out of the natural resources and fossil fuels present in our nature and with times these resources have seen a greater loss and have been decreasing thus we are left with not much if resources. These have also led to spoil the climate of our environment as carbon emissions from the vehicles and industries which consume them for energy generation has led to increase in the carbon content in the atmosphere leading to rise of earth temperature and thus climate related problems. Thus we can see how bad have humans deteriorated this earth with their actions in search of a better life. 

So what can be the possible solutions in such conditions of difficult times. People do suggest that cleaner fuel and sustainable resources like wind and solar energy can be utilized to fight these prevailing issues. Solar energy is widely available energy and we can use it for better use along with wind energy also. But we can not directly shift to the use of much cleaner fuel and energy sources instantly because:

 

  • Most of the power still comes from the energy generated from coal in various industries and most of the countries still don’t have much if technologies to shift to these natural energy sources for power generation. 
  • 66% of power we consume comes from coal and other fossil fuel consumption. If we stop it, we wouldn’t not be able to get much power for our daily usage. 

 

 

  • Instantly stopping fossil fuel, would let a great stop to our travel and other related things as we would not have fuel to power them. 
  • We would not get out food and other necessities since we won’t have the sufficient sources for delivering them.
  • Plastic for storing food,making parts of machines and various things would not be possible as we won’t get energy for manufacturing it.
  • But also the main problem would stay for many decades as according to scientists, they believe that the carbon emissions and other gases are trapped in the atmosphere and thus would require time to get away. 

 

This is the right stage and time for humans to understand the need to shift to much cleaner sources of energy. It’s not possible instantly since there would be a lot of problems doing so , but we can at least start small, by slow building technologies and fuels which would be Eco-friendly and safe for us as well as earth and much cleaner to that which we use at current time. We all need to step together in this journey for better future and thus save this planet slowly but effectively.

“Nuclear And Other Sustainable Sources For Cleaner Energy.”

Humans have been working in the field of generating power and energy in different forms. We in this 21st century require energy for different aspects, be it for cooking food, fuel for travelling, for running industries and many more. We have been using natural or fossil fuel for generating power, petrol, diesel for fuel in cars and other vehicles, coal for powering industries and even generating power and many more. Thus these resources have helped us to make our lives more comfortable and easier. But With times the utilization of these fossil fuel and natural resources, our environment has seen decline in its ability to provide better and cleaner output. Our natural resources be it air or water, have seen a greater degradation and our food resources have become in health. Also concentrating in the fact that these fossil fuels have also been decreasing as are expected to exhaust soon. The point to consider is what next then? We are in the situation that if we use these fossil fuels, our environment would get affected and also phenomena like climate change and global warming would increase if we stop using them, we do not have a better mode of power generating at a certain notice. So what can be done? 

We have been working in the field of generating power through nuclear energy. This is expected to be the most cleaner and effective way of generating power. These have been in existence for a while but still we do lack proper knowledge of how to better use it since it is a risky source of power generation and humans are at the risk in operating it, we have been using it less. But nuclear power can be the future for generating power. These have enormous power to generate enough energy for the population and their needs to be fulfilled. But the question to its usage is the economical and health aspects. These plants and their installation cost a lot to the economies and also the health issues are enormous. We do not have much skilled labor and people to operate these machines. 

We know that these nuclear power are effective but not 100% secure. So we must shift to better and cleaner along with safe mode of power generation. Solar energy and power through windmill are an effective source but their installation as well as most of the countries do lack much of skilled labor to shift to these technologies. Also if we do stop the usage of these pollution causing fuel, it still would require many decades to solve the issue of global warming and climate change. So we must develop more and more cleaner modes of energy generation so as to make our earth a better place with better and cleaner sources. Energy and power generation is an increasing need for the population around the world and we must shift to operate better and best ways of energy generation as soon as possible. The prior need of the hour is to understand the requirement to save our environment and the resources in it and make our earth the way it was.

“White holes – Real Or Hypothetical?”

Space has been a place of mysteries for humans ever since we have started studying it. Various phenomena happening in there and science related to it has always fascinated more and more to know much about the place we live in. These all ideas and researches have helped us increase our knowledge about space but still a lot is still pending to be found and various theories yet to be solved. We have heard about black holes and their power to let anything in and not let it out and how even light cannot escape it this is considered to be a destruction factor for anything which travels around it and thus gets into it. The significance of black hole was unknown until it’s provenance was recorded by scientists in 2017. So this has been a great discovery for us and various other theories which have been given by our scientist. 

But another theory which is till date considered to be hypothetical is the theory and existence of White Holes. White holes are entities with properties opposite to that of black holes. This means that instead of absorbing things and letting them into it, these holes push things out and resist anything to enter them. These consist to be hypothetical as their physical significance are still a doubt for the scientist. Physicists also question its existence since they believe that it doesn’t agree to the 2nd law of thermodynamics according to which the entropy of any object of something either remains constant or increases but does not decrease. But still many scientists believe that it could exist, which is because as we know that black holes do emit energy in the forms of radiations as given by Hawking’s radiation theory. So doing so they keep on losing energy and one day they get destroyed. “But the question is what next, what about the things gone inside it?”. This is where scientists think white holes form and during the death of black hole it converts into white hole and this gets everything out of it.It seems to be a valid theory and many scientists do believe in it. Also the story of how our space was formed is related to being from a Whitehole, like we know everything came out of a small dot and thus creates these things. It’s just a second thought on the big bang theory, but still scientist still doubt on its existence. 

But some pictures taken by nasa were fascinating and interesting which were related to what we are discussing about. In 2006 Nasa recorded a big supernova-like phenomenon some light years away with a time more than any other recorded till then. Soon after it was recorded that it just got lost leaving nothing behind. Scientists are relating it to be a white hole phenomenon.But assurity of these holes are still not found and also seeing the laws defined in our science, we do not see their existence. But also we know that many things in our space do not follow these rules and regulations and thus these holes may be one of them challenging our governed rules. 

So maybe in the future we would be able to visualize or see a phenomena of white holes at some distant light years with better technology and research work by our scientists and experts and thus we could convert another hypothetical theory into a reality.

“Yoga – India’s Heritage”

India is known for its great culture and traditions, which are famous not only in the country but around the world. These have given humanity new definitions and ways to live life and the real way it should be lived. The ideologies and sayings from Mahabharata as well as obeying and respecting elders and every other person around us from Ramayana, teachings from Lord Buddha, and many more have been given by rich Indian culture. But along with the stability of mind and soul, our culture has given this world ways to remain fit and healthy also.Thus age old practice is widely known as yoga and India has been the place for its origin and it’s related study. Yoga is adopted as a way even science provided us the proves which has capability of providing health benefits. 

Yoga provides the best ways and rules which define the right way, right diet and right norms for any human to live life it’s meant to be. Yoga includes mantras, pranayama ( breathing exercises) and other physical activities which help humans to stay fit both internally as well as externally. Yoga provides every individual internal peace,removes all kinds of stresses, tension and pain and gives him/ her the knowledge of our older traditions and how our ancestors used to live with it. 

India is considered one of the best places to visit and perform the activities of yoga. Many people, every year travel distances around the world either to learn it and inculcate it in their lives or to learn and then bring the knowledge back to their places as trainers and teach there. Most of these yoga training centres and camps are concentrated near mountains and river places so as to give a touch of nature. Surrounding the beauty of nature, people live to perform these yoga exercises and activities, which bring them close to nature and feel every single part of it. Many places do offer free camps and workshops so as to increase the awareness of yoga and its benefits and motivate them to include it in their day to day routine. Also to celebrate the richness of it, we celebrate world yoga day on 21st of June every year. There are various programs and workshops which help people develop the knowledge of yoga and it’s enrichment in its activities. Any individual who wants to bring out peace and calmness in their life and also teach it to others as a trainer can learn it.

In today’s world where we see pain,stress, tension and various other social issues increasing, adulterants In Food , impure water and unclear minds, yoga provides an atmosphere for our brain to calm and helps to figure out best possible solutions at these tough times. It opens the doors of humans’ thinking abilities which not only helps to get better ideas and better approaches to find them. Yoga has proven to be a beneficial for humanity and following these activities and teaching we can bring the peace and freedom to actions along with spreading our age old traditions and culture around the world.

“Moon Base – Possibilities And Associated Difficulties”

Humans have been interested in space and it’s associated phenomenon since ages. Which has really fascinated humans to go much deeper into space studies and know space better and solve the mysteries residing out there. This journey as we all know started as a fight between the two countries at the time of the late 50’s which were Soviet Union and The United States of America. But as soon as they came to know that it’s much bigger than just a competition, it became a field of much more investment of both money as well as research and new ideas. The first manual landing on the earth’s natural satellite changed the dimensions for humans as we could imagine humans travelling outside the planet and thus have a close look to space and its constituents. Considering all this, humans were planning to set up a proper human base, so as to develop knowledge about the age-old regolith present there as well as find better resources for human travel. 

This all sounds interesting and fascinating, but how easy it is to set up a proper base with humans working all around Or people visiting as travelers on it and many more scenarios. 

 

  • The first problem which is a major one is to shift such heavy material or construction material through spaceships to the moon, which will cost billions and trillions of dollars, and the cost of building would be different too.
  •  Also it’s not sure that these constructed bodies would be able to stand still and strong at the surface of the moon or not get affected due to gravity and other factors such as meteors colliding.
  • We know that the moon doesn’t have a proper environment or shield which would break the coming meteors on it, thus these meteors impact the moon and form crater or big holes on the moon. This is very risky for us as well as our human base as our efforts would get dissolved and a big loss for us if our base gets destroyed and humans get hurt.
  • Also we would be requiring much water, food resources for people working over there.
  • One of the other major areas of concern is the radiation from the sun, which comes directly and this could be very dangerous for people working over there.

 

But most of the solutions were found for building bases, as in 2014 , a company named Made In Space brought the concept of 3-d printing parts in space. They tested making things with some plastic and regolith (moon soil), and made things out of them. These were really strong enough of handle heavily stresses. Also it was mostly automatic with little interference of humans. Thus this technology can effectively be considered for building out things in space. Also scientists believe that, there are tubes under the surface of moons, which would not only save us from the meteors, but provide effective temperatures to work in, save humans from radiations and also save much of our resources building human base, as we could consider them for the same. But the only reason to worry is that we do not know that, either these tubes are active or not. Since these tubes as we know carry magma in them from the moon core, so if some of them still act to be active then that would prove to be a problem for humans. 

Scientists and researchers are working in the field of developing new technologies and systems which could surely turn out to be a key changer in the lifestyle of humans. Would help us to reach the farther of the planet and also make it feasible to even live on them. “But it’s not a task of years, it’s a task of decades and centuries, so our initial steps towards developing better can turn out to be a stepping stone for our future generation to see and live what we just dream of”.

“Diet And Its Effect On Human Psychology”

Diet or food has been an important and essential source for survival of mankind. It provides the basic energy and elements helping us to perform day go day activities and keeping ourselves healthy and fit. Humans have been traveling since times in search of better food resources along with clean and pure water resources and better shelter opportunities. With time humans’ diets have transformed and have seen a greater impact on their behaviour as well as their health. Today most of the people try eating vegetarian and vegan food as compared to non vegetarian food. But along with that the concentration if junk food or food lacking basic nutrients have increased in the market as they offer better taste. This has surely resulted in a rise of aggressive behaviour and less level of patience especially among the youth. 

Scientists have researched on the topic of “How diet affects human psychology and What are the associated behavioural aspects as well”. They did find a great link between food and human psychology. There are various tests and experiments which show that eating junk food brings out more and more aggression among people , reducing patience level and filling them with feelings like anxiety and stress. There was an experiment testing the decision capacity of individuals after giving them both a nutrients rich diet and a nutrient deficit diet. It was recorded that the person who ate health was able to think and decide better as compared to other people. There were many other experiments which did show that people do get fascinated towards these junk food because of the it’s ingredients. It came up in studies that sugar is more addictive than cocaine and any other drug. Junk food has a good amount of sugar in it, so whenever people see these junk foods, they have an urge, which truly drives them to eat it. 

Scientists relate this aspect of humans with the food they eat as most of the just k food lacks essential proteins, carbohydrates, fibre and omega-3. Omega 3 is essential as it reduces blood pressure, heart related disease and prevents stroke. Other proteins, calcium and iron help the body to grow and remove daily muscle fatigue. Junk food contains sugar, which increases the risk of obesity, diabetes and most probably heart related diseases. That’s The reason why heart attacks and other problems related to cardio have seen a hike. People usually prefer these things so as to calm their Taste buds which they often do not get by eating healthy food, since most of it lacks taste. 

People should understand that especially in today’s era of pandemic  we need to make our immune system strong and make ourselves fit and healthy  but eating these unfit and junk food won’t let us grow better and healthier. One can have them but in a limit. Everybody has their own daily protein, carbohydrates, fiber, vitamin limit  and if it’s not fulfilled, the body goes on degrading and the body seems dull and unhealthy. So one should try to eat better, healthier food, along with exercising on a daily basis, which will not only make them fit but also encourage other people in their surroundings to get fascinated by the results and will shift towards betterment and thus a better way of living with healthy humans all around.
