I've read several articles that are predicting the collapse of society by 2050. With the end of humanity following since we have trashed the planet and Trump has been rolling back clean air and water laws. It would almost be a relief. I mean why do humans deserve to exist? If you try to take an objective look at our species we are horrible creatures. Hunting animals to extinction, destroying the forests that produce the oxygen we rely on, using pesticides that kill the insects that not only destroy our crops but also the ones we rely on to pollinate them, etc. I could go on but humans are en masse a horrible species. Maybe the dolphins will evolve and do better.
