The animals don't have to turn against us, and the planet has no reason to destroy us either, you see, the only thing we are truly destroying is our livable environment.
The planet will be fine, the human population will destroy itself.

The planet knows that human will kill the planets ability to sustain human life.

Many other forms will recover. The Earth will repair itself. And will likely leave us out of the next improved version in about 700,000 years.

When your enemy is destroying itself, let them.
