On the 27th, the “Chemical Aid Global Sustainability†report jointly issued by the Chinese Chemical Society, the German Chemical Society, the Japan Chemical Society, the Royal Society of British Chemicals, and the American Chemical Society issued an early warning: the current global output of phosphate fertilizer has reached its peak, and will Gradually decline in the later part of this century, because the phosphate rock resources used to produce fertilizer may be depleted in the next 30 to 100 years. This will cause the phosphate fertilizer market to fall short of supply and increase prices, further threatening global food production. The food crisis will gradually appear when the global population approaches 9 billion in 2050.
The report also pointed out that chemists can address this challenge through technological innovation and the development of new sources of phosphorus resources.
The survey shows that phosphorus deficiency in soil is particularly prominent in Australia, the world’s seventh-largest wheat producer, and sub-Saharan Africa. In sub-Saharan Africa, phosphorus deficiency has severely affected food production and millions of people face malnutrition and cyclical famine. Most of the world's phosphorus resources are in China, Morocco, and the United States. At present, humans have not yet found natural resources that can replace phosphate rock. In recent years, as the demand for phosphorus has soared, the global market price of ammonium dihydrogen phosphate has doubled. The report calls for global scientists to ensure the future supply of phosphorus through technological breakthroughs and is optimistic about this. The report believes that human beings can use chemical methods to develop new materials and develop new phosphorus resources, such as phosphorus-containing substances in rivers, oceans, and soils.
This report not only raises the "peak phosphorus" warning, but also predicts that monopoly or political instability will lead to shortage of other natural resources or soaring prices. These natural resources including rare earth elements, precious metals such as lithium, platinum, and palladium are all raw materials for the production of daily necessities, and humans must strive to find alternatives and increase the extraction efficiency of existing resources.
This report is a summary of the four-day CS3 summit organized by the five-nation Chemical Society. Thirty international experts from the material field participated in the summit. The purpose of the summit was to seek solutions to the most challenging problems in the world.
Prof. David Philips, chairman of the Royal Society of Chemistry in the United Kingdom, said: “The concern about global warming will sometimes cause humans to ignore other consequences of the population explosion and resource depletion. This report reminds people that resources are Limited, some resources actually have a shortage, and this report also conveys positive information to people, that is, chemical workers can provide a sustainable way of social development."
