The more people we have, the greater the suffering. But how? Real life problems like famine, poverty, disease and more (Overpopulation is still the problem, Tal 1). There is no escape from these problems, no matter how much we do to try to prevent them. The Earth is only so big, and that's why we'll have to make it last until we find a way for humans to live on Earth. Mars possible. Today this is a long way, so simply by avoiding littering we could preserve the Earth a little longer. We need the Earth to live. We will become extinct due to our own actions and other species will remain there. We must act to stop overpopulation. We are running out of land. Without the land we need to support crops and wildlife, we will simply starve. The less land we have, the less wildlife, and the less wildlife, the less food. The Earth is a very delicate system and we must keep it in balance in order to live in peace. We need to stop overpopulation and there are many ways you can do that. One of the easiest ways to do this is to set a limit on children. For example, if we could only have one child per person, eventually the world would not be able to continue growing, because people would die at the same rate at which children are born.
