What will happen to us in a thousand years, and what will happen to the earth?

Don't say that in a thousand years, the world population will reach 9 billion in 2050. It is equivalent to 500 Shanghai. The earth has never raised so many people, let alone so many modern people. The problem is self-evident.

1, pollution, modern people frantically consume the resources left by the earth for billions of years, seriously overdrawing the wealth of future generations. Air, sea and land pollution can be seen everywhere, and the problem of rising temperature and climate change is very serious.

2, diseases, new diseases emerge in endlessly, fierce and abnormal, Ebola, SARS, AIDS, bird flu, everything is fatal, if there is a deadly, infectious, long incubation period virus in the future, human survival will be in jeopardy.

To sum up, the next Millennium of mankind is not optimistic. Once human beings are extinct, it takes only 200,000 years for nature to completely erase the traces of human existence on the earth's surface.
