There is only so much air and water on earth. These ubiquitous resources are not infinite. Not believing change is possible is like mistaking “the world is flat” or “the sun goes around the earth”. Changes to climate caused by global population growth are easier than one may think, one way or another, if only we can or cannot change the human will to survive and coexist. Let’s give mankind credit for ingenuity, this time and for all, the better.
To believe change is not possible is a hoax. (fake news)
