On a second thought, i totally agree with you. But lets see it this way. Maybe if the number of these "greedy" humans didn't increase too much, i guess the effects they're having on the Earth would have minimize a bid and we won't be talking about distortion in Earth's balance.

Just like i mentioned in the post, they could easily showcase this greed through science and technology, that's why our natural resources are dwindling so fast.

So you see, it still balls down to increase in population and advancement in science and technology. Without these two, humans greed has little to no effect on the Earth.

Thanks for stopping by, i really appreciate.
