If God created the Earth then did Satan create humans??

Although I'm an athiest I ask this of christians. Seriously, humans do seem to be the work of the devil. We are destroying the planet. All the rapping of the land for it's natural resources like clear cutting and minning. Then there is the pollution contributing to warming. And most important, what about the wildlife from the already extinct dodo bird and penger pigeon, to the critically endanged pandas, amur leopards, mekong catfish (google them) ect, ect, ect, ect. What made me think of this was the re Anderson Cooper/Jeff Corwin show that stated that 90% the wildlife on the island of Madagascar cannot be found anywhere else on earth and now only 10% of the islands rainforests are left. Yes, if I believed in Satan I would say that he created Adam and Eve.
