Charles Darwin theory only promoted the concept of ‘Survival of the fittest’. Everything in life whether be it in a singing competition or TV shows like American Idol, Ripley’s believe it or not(where a man eats cockroaches to survive his day), everything is related to man which adds meaning to his survival. Every day is a survival day, each day he/she has to go through some task to prove himself to be survival of the fittest animal. But, here is the list of basic things without which a man cannot survive.
Human survival is least possible if there is no consumption of food. Food is meant for survival and also for producing energy. Survival food is meant to keep the human body struggling for longer period of time to work and do muscle powered work. Not only does food provides with essential nutrients like vitamin, carbohydrate, protein to sustain our body in the long run. Each of these nutrients are broken down within our body so that energy is produced and just like a running engine requires coal till the coal is burnt to produce steam which keeps the engine running.
Water is the most important criteria to keep the human evolution running. Life without water, is like life without oxygen. Humans need water to live, plain and simple. We lose water through sweat, urine,waste materials and even breathing. Water is the only source which is used to make the organs of our body keep running. Especially kidney is one of the most vital organs and the water flushes away the waste from the whole body and removes heat and waste material as such. Even the food we have needs water to get it digested. Even if you don’t want to have water, your body will demand for water when you are thirsty , that is the signal which signals that our body needs water. A man can survive without food for weeks but without water, it becomes miserable.
As per Maslow’s Hierarchy of Needs: shelter (what we in today’s modern sense call it home/house) is one the important basic need for the survival of human beings from natural elements and from other hazardous elements whether being it a living or non-living being. When man was not a a man, but a ape, it was the basic instinct of every human or for any being to protect himself and one of his own members. If all the needs including food, water and shelter, these are the basic need which motivates us to do any kind of work and also help us for self actualization. A man can survive in any place whether be it a cave, on the top of mountain building a tent . that’s all we (humans) need to keep us going no matter what.
One cannot keep a man out of the land. Land provides for enough space to live oneself in some way or the other. These are the list of resources which are essentially needed to be produced : food, water , shelter . It is not a delusion but without land even four legged animals cannot survive. Tribes who live their lives of primary times but they also need land to sustain themselves. Land is the basic need for the civilization of man. That is how land has helped us to grow out from the primitive cocoon and become a MAN. That is why we are not yet scavengers. Land which earlier helped us to grow agriculture but it today has helped us to become a CAPITALIST animal.
5. Interaction with other beings
To quote Aristotle “Man is by nature a social animal; an individual who is unsocial naturally and not accidentally is either beneath our notice or more than human. Society is something that precedes the individual. Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god. ” these words are enough to make us believe that man cannot live alone. Human nature is such that one cannot live without interacting with other beings and man always wants a company and without which he cannot think, play, work and develop. That is what makes man a modern animal.
