Everything has a future.
Cosmos, planets, countries, humans, creatures. ......
Thinking and creating about the future has brought extraordinary significance to our life.
There is a special knowledge called futurology.
Some people think about the future like this: what will happen in the future? No one has an accurate answer, even the most authoritative scientist now. But from the documentary Future Earth, we can see that the future earth will become nothing, that is, it will return to where it came from, and the earth will become dust in the big universe. Humans should always pay attention to the future, and our planet will eventually decline. Even if we can't wait that long, human beings are always faced with sudden and dangerous threats such as asteroids and large-scale epidemics. Therefore, countries with relatively advanced science and technology, such as the United States, China, and Russian, are striving to develop outer space for our future (of course, a large part is for military and current interests). What we have to do is not to think about what will happen in the future. What we must do is to protect our environment, so that our future generations will not worry about their survival. After all, it won't take decades to immigrate to other planets. I think that's the point.
