WHATS IN MY BIG QUESTION FOR ME

Something that is in my big question for me is that I will finally get an answer to something that has been on my mind for a few years. I have always seen people not care about what they have because they can always "get a new one." But, there is only ONE earth, therefore we can't get a new one that easily. So many humans don't realize that we are slowly killing the earth and when its going to be too late, they will finally realize that we had time to save the planet but because they didn't care, here we are, with a dying/dead planet earth.
