All populations have a limit

“All populations have a limit” means that a population can’t continue to grow to infinity. This is because of space, food, housing, money, and everything else that it takes to keep a population healthy and strong.

On the bottom of the graph above, there are numbers which indicate time. It started at 500 BCE to 2025 CE.  On the other side it has numbers of how many people there are in the world. If it continues to increase at the same rate, then there would be too many people and not enough room, which means that there would not be enough food, jobs, housing or money.

If this was a shark population, then the sharks would starve to death. In the experiment we did, if sharks didn’t eat enough minnows, then they would become extinct. Well guess what, that is the same thing that could happen to humans: we will not survive much longer if the population is still going to keep on growing. We have to have a plan.

One idea that might work is that we only allow one kid per family, or we just keep it how it is now and hope for the best. Whatever we do, we will have to figure it out soon. Or else future generations will all die.
