In your opinion based upon Earth after people what is the biggest impact humans have had on the planet?

Humans have taken many things from the earth and enhanced them with man made postilion's and other such things that change us. These things may give us more from the earth but at what coast? We're killing off bees which supply us with a third of our food and other such animal types such as the dodo bird, mountain goats, and many other things that affect the food chain causing more animals to go extinct, Just like the polar bear.

If it wasn't for trees we and all the plants around us we would be unable to breath and with the fumes from cars we are slowly killing our ozone layer which is letting the suns heat reach us but not leave causing the world to then over heat and in the end the waters in the world will raise about twenty feet causing most of the land to be under water. For example, north America will be covered in water, except for central America.

All these building that we have built and other things such as the Ifle Tower which are built to seismic standards yes but is no match for what the can really do. All we have done is taken the earth and domesticated it. Its animals, used its natural resources for our own selfish reasons and we will all die from it. The biggest thing we have done to this earth is just to use it for selfish reasons.
