How long can humans survive on Earth?

The existence of human beings on the earth, according to the current situation, does not depend on the changes of nature, but also on the degree to which human beings develop and protect nature, and now we already feel the threat of nature.

The best way for human beings to survive is to live in harmony with nature, this harmony is not so simple, the current harmony is the development of science and technology in the case of the effective protection of nature today, but this effective protection is not so easy now, because we still need to develop our science and technology, as long as the development of the economy will be for the acquisition of resources, will carry out certain damage to nature, this destruction is not good for the development of our human survival. <>

The earth has given us too much, we now have unlimited requirements, will carry out endless destruction of nature, this destruction will directly carry out certain damage to our living environment, how green the earth was in the past, in ancient times we lived in harmony with nature, especially in modern times, our science and technology, this technology is good for us human beings, for our society to promote a certain role, but for the environment is destructive. <>

Global warming, the melting of global glaciers in a large area, the rapid reduction of global freshwater resources, the rapid deterioration of the human living environment, the global concentration of carbon dioxide is increasing, the ozone layer in the atmosphere is destroyed, the ultraviolet rays in the universe irradiate the earth, and the earth's surface is becoming more and more dilapidated. <>

Human beings really have a very serious damage to the environment, but this is serious for us human beings to destroy, but this damage we need to use technology to restore in the future, if we don't recover, then we humans will really disappear from the earth in a short period of time, this disappearance is not natural, but caused by human beings.

It is our desire that humanity should take care of our environment, protect our home, and enable us to live in our home planet for a long time.

According to scientists' speculation, the sun and the earth still have 4 billion years to live, so humans can only live for another 4 billion years.

About 400 million years. Because the life span of the earth is 5 billion years, the earth has been living for 4.6 billion years at present.

If human beings can know how to take care of our nature and ecological balance, then we human beings will definitely survive for a long time, or even forever in the world.

I think that if we can protect the environment, we can live for billions of years.
