Why Stephen Hawking said We Must Colonize Another Planet Soon?

As a result of measuring social development for 10,000 years from 8000 BCE to 2000 CE, almost all of the progress made by mankind has been made in the last 200 years. The power generation index, which was less than 50 points in 1800, increased to 736 in the year 2000. It did not increase 50 points in 9800 years, but it increased by 700 points in just 200 years. If this kind of development trend continues in the future, the collective power of mankind will rapidly improve to a level beyond imagination, and exploring colonization in space will never be far from the future. Future development pace The development of science and innovation of technology will continue anyway. But will the development of science and technology save mankind?

Dr. Stephen Hawking, who predicted that the Earth would be destroyed within 1000 years, would be the main culprit of nuclear war and global warming. Humans will need to colonise another planet within the next 100 years to survive climate change, according to Stephen Hawking. The first is a massive war involving nuclear weapons, including nuclear warfare. Many scientists believe that the use of nuclear weapons as well as the use of nanotechnology and biotechnology can end humanity.

Another problem that many scientists have pointed out as a threat to the future of humankind is environmental destruction, including global warming. We know about the various risks associated with global warming, but we do not know about its seriousness. Global warming threatens biodiversity and food production systems as well as increases sea level rise and meteoric rise. It is said that warming can trigger an accelerating mechanism that triggers warming, and it can become devastated like Earth in or even become hot like Venus.

A recent study by Nature, the world's most prestigious science magazine, predicted that the 6th "extinction" will take place on Earth in the coming year of 2200. The most serious of the great extinction of the past is the third major extinction about 250 million years ago, where 96% of marine animals are extinct. The above study predicts that by 2200, 41% of amphibians, 13% of birds and 25% of mammals will become extinct. Habitat loss and destruction due to human intervention and development are the major causes of the 6th extinction, and global warming is also an important factor. The rate at which animals are already extinct is about 1000 times faster than 60 million years ago. Experts emphasize that this phenomenon can eventually lead to destruction of humanity. There is also a warning that the number of bees and bats will decline and eventually the food production system will collapse.

Is nuclear war a problem, and global warming is such a serious problem? Are there any more serious threats than these? There is a possibility that the earth will no longer be a nesting place for mankind because we can not help it, such as the collision with a large meteorite or asteroid, the huge volcanic eruption, the advent of the Ice Age. The Earth has sometimes faced these kinds of things in the past and has suffered extinction. The extinction of dinosaurs due to meteorite collisions is only one of the best known examples.
