From now on, you are not going to start a family any time soon, because I heard that Earth is going to be crowded with so many people, that biodiversity will soon start failing. Overpopulation is a huge problem, and this is why we're not going to have any families for the rest of our lives. Not even I'm going to have a family. Also, to those who want to have a family in the future, I sincerely apologize for making you mad. Besides, there are other important factors in life than family, such as friendship, respect for ocean life, and more.
You read the thumbnail. Earth can only handle 2 billion people, not 8 billion people. Why don't you go watch The Lorax and see if I'm telling the truth? Also, WALL-E is another movie that explains why we shouldn't rely on technology to improve our lives. So, both The Lorax and WALL-E share something in common: they try to warn us about what's going to happen to Earth in the future.
