Everybody probably is time to accept that human nature – it's selfishness. The desire to obtain for themselves, this is the main desire in life. Without it, man does not exist. But in nature there is no selfishness, all live by the principles of return, together harmoniously co-exist and how often it happens, if one element is lost – it causes an imbalance in the system. So everything – yet who is this man? This is something special that lives outside the laws of nature? Why? It does not want delve into the philosophical discussion about the historical roots of selfishness, but that man is separated from the natural environment – a fact even worse, all his activities with regard to nature is directed at her unsuccessful submission. Can an example. If a person is the sum of its elements, to the most basic and all their activities are aimed at subsistence of the body, what happens when a virus? Huh? The virus tries to selfishly take over all the resources at its security adaptiruya for themselves and destroying everything that opposes him. For a time he does, but the body, all its elements rallies, isolates a virus, disarms (wins) and adapts (gets immunity).
This is the normal course of events. Of course there are exceptions. Where the body is not able to resist the danger – he locates it at the expense of their life, such as cancers, etc. Now if we look at human behavior with respect to nature, we are the same virus.
