What an irony! ... Human beings claim to be intelligent creatures, but they do the most... Things that harm nature.
Development for money and benefits ... Recklessly, claiming to be the "judge of the survival of the earth". Wait until you really realize: all things symbiosis... It is the complete earth, at that time, I don't know that the species are extinct and disasters are raging... The apocalypse has been carried out... This step.
Complex human ecosystems, doomed... If it is not to the point of cornering, it will not be a simple problem (it can be solved with money), and now, we are... Taste of your own medicine.
