Our planet is a beautiful one, but sadly, we humans haven't done our part to show it proper respect or treat it in a way that will keep it intact over the long run. Mankind's activities have done undeniable, potentially irreparable damage to the Earth.
According to world-renowned physicist Stephen Hawking, humanity has maybe another 1,000 years left on Earth. Our only hope to survive extinction at that point is to colonize other areas of the solar system.
Recently, NASA released a series of images that show just how much damage humanity has done to the world over the last few years.
