The nature is a living organism. It feels the pain. It can suffer just as we do. The humanity has been exploiting it for many centuries. We have always seen the nature as an inexhaustible well of sources only. But now we know that one day sources will be run out. Ruthless exploitation makes a great damage to the nature. Our growing appetite cannot be satisfied by it. We should develop new ways of using the sources. These ways lead to Eco Economy.
