lets be logical about this.we have here humans vs earth meaning humans (about 100 -200-300 thousand years? history ) versus earth (about what?4,5 billion years of history?)
and so we are in a point now that we think we are a threat to earth...laughs.
well earth has been through a lot of stuff much worst than those tiny little creatures that walking on its surface can create like massive volcanic erruptions meteor showers shifting of the poles moving of tectonic plates and other similar destructive forces and survived and we think we are a threat?
the planet will shake itself for a minute and we will go bye bye instanly ....
the earth is fine...we are screwed...
