Every year the population of our planet increases, and the resources for food are becoming less and less. In this issue we will talk about what this may lead to.
According to the calculations of the United Nations, by 2050 the world’s population will exceed 9.5 billion people, and by the 22nd century this figure will exceed 11 billion. The current growth rate is about 230 thousand people per day, which, of course, threatens not only the ecology of the planet, but also increases the likelihood of global hunger in the next century. At the same time, it will be important to note that by the end of this century, 40% of the inhabitants of the earth will be Africans, because it is not on this mainland that the large-scale demographic explosion has been observed for several years now, where 70% of all people on the planet lived 70 years ago.
In June 2017, at the StArmus Science Festival in Norway, the famous scientist Stephen Hawking said that people should start leaving Earth in the next 30 years, otherwise we are all threatened by overpopulation and climate change incompatible with life. According to the scientist, Mars and the Moon are the best places to create the first settlement colonies, where in the next 30-50 years it will be possible to create full-fledged bases for human habitation. At the same time, it will be important to note Stephen’s statement about the threat of asteroids, but on this topic we have already made a release, a link to which you will find at the end of the release.
Consumption of fresh water is becoming one of the main problems of the Earth, because only in the last 50 years it has tripled, and according to scientists’ estimates, by 2030, 40 percent of the world’s population will be threatened by its shortage. This is likely to cause intense migration from Africa and armed conflicts in the Middle East and Central Asia. It is noted that most of the water is used not for drinking, but for irrigating agricultural land, including with food for livestock, which is no less important a problem. The fact is that farms that contain cows and pigs are responsible for the release of more than 60% of the greenhouse gases on the planet, which slowly leads to its extinction.
In conclusion, we would like to say that in addition to the resettlement of earthlings to other planets, there are other ways to postpone the death of mankind. First you need to reduce the birth rate by limiting the number of children in law, as is done in China, and by increasing the availability of contraceptives, the lack of which, among other things, led to the fact that the average family in Africa has from 4 to 5 children. And of course, it is necessary to reduce the consumption of red meat, which causes the greenhouse effect and less wasteful of the water resources of the planet.
