The problems is, for all the "good" things you mention you have to mention the bad:
Wars, land mines, guns, pollution, over population, fanatical religions, greed, cruelty, the extinction of animals, the destruction of the rain forrests, drug dealers, and much much more.
We humans think we are the most intelligent creatures on earth, and in some ways we are, but in many many others ways we are not.
This planet would have a longer more pleasant future if all the humans died out and it was left to the rest of the animals to live here into the future.
