Soil erosion as big a problem as global warming, say scientists
[2023-12-29 12:27:24]
Yesterday's researchers threaten contemporary civilization as erosion of surface soil - this is a serious problem in Australia, China and some parts of the United States - threatens long since society disappears I warned.
Jared Diamond, the creator of the guns, bacteria and steel at the University of California Los Angeles, to the American Association for the Advancement of Science yesterday was part of a fertile new moon that started 10,000 years ago, once the wealthiest He said it was the most innovative. Sex, the world's most advanced country. However, today it is "basket case". This is mainly due to "soil problems, salt watering, erosion, deforestation".
More than 99% of the world's food comes from the soil, but experts estimate that more than 10 million hectares (25 million acres) of agricultural land is deteriorated or lost by rain or wind blowing off the topsoil every year. According to the data of the United Nations, the region enough to cultivate Europe - about 10 times the UK's 300 million hectares - has deteriorated seriously and can not produce food.
Ward Chesworth, a spokesperson at the University of Guelph, Ontario, said agriculture produced 'agricultural wounds' on the planet, which would affect one-third of all appropriate soils.
The past society collapsed or disappeared due to soil problems. Professor Diamond said Easter Island in the Pacific is a famous example. 90% of the population dies due to deforestation, erosion, and soil depletion
"This is extremely serious as society ends cannibalism, the government has been overthrown, and people have declined other statues, another example is the Pit Cairn and the Henderson island in the South East Pacific. One example is Maya in Mexico and the civilization of the Yucatan Peninsula in Guatemala, people survived, but about 90% of the population was lost, "he said.
Other examples include Iceland, where he said that about 50% of the earth eventually falls into the ocean. Icelandic society can only survive at very low standard of living.
He said that the media is concerned about fossil fuel problems, climate change, biodiversity, logging and forest fires, but it is not on the soil as it is not noticeable
"There are serious environmental problems beyond dozens, they are all very serious, unless we solve 11 of them and solve the twelfth problem, whatever the twelfth question, anyone I can help you. " "Many of them have caused social collapse in the past and soil problems are one of them." 66
The microscopic keywords are "human" and "sea level rise". Therefore, we must make a note of the major problems of global warming and all the problems associated therewith (such as increasing windstorms, extinction of certain animals, soil erosion etc). For example, talking about problems affecting "planet", "animal", "atmosphere" can not answer this question. Action words are problems and solutions. Therefore, our job is to write this as well as this. It does not ask us for advice, it does not handle disadvantages, benefits and reasons, problems or solutions only. Talking about the cause of sea level rise, I will not answer this question.
Some scientists say global warming is a big problem. why? It is not because it warms the earth as it absorbs trillions of dollars into the problem that is good for our world. When asking the children of the high school, carbon dioxide is absorbed by the process photosynthesis and turns into oxygen. Even if the amount of carbon dioxide increases, plant productivity does not rise and oxygen increases. About 18,000 scientists completely opposed the Kyoto Protocol in the petition of the Oregon Institute of Science Medicine. The country that is the richest and burning fossil fuels signed the Kyoto Protocol of reducing greenhouse gas emissions and burning fossil fuels. An article from their petition concluded, "The prediction of harmful climate effects due to the future increase of trace amounts of greenhouse gases such as ca
