    Instead of raging in the comments about whether or not humans destroyed earth, just be grateful for the fact the we are alive to experiance the earth as it if. Who knows it might get even worse in a couple hundred years! So instead of complaining about what humans have done so far, actually EMBRACE what weve done whether it be man made or natural :)

    In my environmental science class we had gone over "keystone" species, and the fact that without them a eco system would become imbalanced and go into a decline of diversity. Now take humans for example: for a long time we were able to increase diversity and still are, but we as humans have the tendency to make the world suit us over other species and we can, in some cases, destroy diversity entirely. So when i read "destroy all humans" or "no don't destroy all humans because we make the world better" it is neither. We should try and live in harmony with other species and seek that equilibrium, but it is hard to the point of almost being impossible; because human nature dictates we seek to better ourselves either on our own or as a group. The issue being we out compete all forms of life on the planet through intellect and the creation of tools/ machines. In short we sit in the middle of invasive and keystone, both destroying the environment we live in and giving it the ability to grow beyond its normal capacity.
