Climate warming, the extinction of emperor penguins, forest fires raging in Australia.

Hawking warned people to find a livable planet as soon as possible and emigrate to space. He believes that the earth's environment will continue to deteriorate in the near future and cannot be controlled. This time limit depends on how human beings protect the earth, maybe 200 years, maybe 100 years.

Nowadays, we can also see the environmental and biological changes around us: serious air pollution, decreased biodiversity, frequent extreme weather and so on. Some scientists believe that the earth may reach its limit in 2050, and mankind will face the test of major disasters. For example:

The melting of Arctic sea ice accelerates the spread of pathogenic bacteria.

The melting of sea ice has opened up a new migration route for marine mammals, making it easier for them to cross from the Atlantic Ocean to the Pacific Ocean through the Arctic Circle. Scientists are worried: "Looking for food in farther waters will weaken the immune system of animals, making them more likely to be targets of virus attacks. At the same time, their search for food in farther waters will affect the overall health of some species, making them more susceptible to illness. Every year, a large number of marine life migrates to the Arctic, which is likely to become an area where viruses breed and spread. "

As the climate warms, emperor penguins will become extinct.

Emperor penguins often nest on the ice under extremely special conditions, so they must be locked on the coastline of the Antarctic continent, but they must be close enough to open the ocean so that birds can provide food for themselves and their cubs. However, with the climate warming, sea ice will gradually disappear, taking away birds' habitats, food sources and the ability to hatch chickens. A warmer climate may make them extinct by the end of this century.

Climate warming has prolonged the mating period of tarantulas, and a large number of giant male spiders have appeared in San Francisco.

The raging forest fires in Australia are consistent with global warming.

This part of Australia is usually very humid and not prone to fire, but now there are signs that forest fires broke out in some tropical rain forest areas last year due to the extremely dry climate for a long time, and now this situation is repeating itself. This kind of forest fire should be rare, but now it has become a normal state, which is very abnormal.

Children may not grow up after global warming.

Climate warming will lead to a decline in food production and an increase in malnutrition. Climate warming makes children suffer from more infectious diseases, malnutrition and stunting, and polluted air hinders their lung development.

Italian astronaut space speech: there is no better planet than the home of the earth.

Many scientists have thought about the future of mankind. Palmi Tano said in a video of the European Space Agency: "From the perspective of the International Space Station, the answer is clearer than ever. There is absolutely no better planet than the home of the earth. " "The influence of human beings is visible and tangible. Unless we take concerted action to reduce carbon dioxide emissions and stop global warming, we will lose more if this trend is not reversed.
