What should we do if the world population increases in the future? The earth can't hold so many people ~

1. Before the population reaches the limit that the earth can bear, human beings have realized the technology of interstellar migration, so the remaining population can emigrate to other planets. Later, if the population becomes larger, the famous writer george lucas described the scene of that day for us in his Star Wars. I can do a little damage here. Even then, the future of mankind is bright, but it will cost a little. You must learn several foreign languages well before you can communicate with immigrants from many planets.

2. Contrary to the situation of 1, too many people can't migrate to other planets, so the consumption of resources will become faster, and the decline of the natural environment and the lack of food and clothing will have an impact on human evolution, leading to the mutation of human genes. This situation is complicated, and scientists have made a large-scale prediction and analysis of it. They think there may be zombies, mutants, vampires and other forms. According to the different stages of genetic changes, they have their own opinions, such as MaxBrooks's The Battle of Doomsday, Stan Lee's Exeter, and Rice's Interview with Vampires. By analyzing these works, we can know that there will be a large-scale war between gene mutants (including zombies, mutants, vampires, etc.). ) and normal people because of poor communication. After a large number of casualties on both sides, the earth will enter a period of peace and the food problem will be solved to a certain extent. So inevitably, survivors need to be familiar with the languages of normal people and gene mutants in order to maintain smooth ethnic exchanges.

In a word, it is very important to learn a foreign language well, no matter what the future holds. This is why Karl Marx, a great teacher, taught us that "a foreign language is a weapon of human struggle".
