According to the authoritative report of the United Nations, "biofuels may be more harmful"
with the rising price of oil and the increasing harm of global warming, biofuels are becoming more and more attractive to countries. However, a report released by the United Nations on the 8th poured cold water on the prospect of biofuels. The report warns that although the use of biofuels may alleviate global warming and provide employment opportunities for poor countries, its harm to the environment and possible social problems will offset these positive effects
will destroy biodiversity
the report entitled "sustainable energy: a framework for policymakers" points out that the extensive use of bioenergy can enrich energy supply, help reduce dependence on traditional energy such as crude oil, and promote the reduction of oil prices. The report said that at present, more than 1.6 billion people in the world do not have access to power supply, and about 2.4 billion people solve the fuel problem by burning straw and livestock manure every day. Bioenergy produced from extracts of corn, sugarcane and other crops will help improve the lives of these residents
biofuels are usually made from corn, palm oil, sugarcane and other crops. For a long time, cheap and clean biofuels have been considered as an effective way to deal with the surge in global energy demand and the greenhouse gases produced by the combustion of fossil fuels. The United States has set a goal that biofuels will account for 25% of its energy consumption by 2022. Some European leaders also agreed that the proportion of biofuels in total energy should rise to 10% by 2020
however, the report of the United Nations Energy Organization, which consists of 20 and no welding treatment, has expressed concern about the promotion of biofuels. The report quoted environmentalists as saying that biofuels may bring about the same or even more serious harm to the environment as fossil fuels. The report said that the rapid growth of biofuels will lead to a rapid increase in the demand for food and forest products, which will put great pressure on the global land and water resources, as well as instrumentation products. At the same time, the planting of a large area of single crops will destroy biodiversity and cause the loss of land nutrients. As a result, changes in carbon rich soils, forests and coal mines may undo past efforts to reduce the greenhouse effectIn addition, the report also points out that countries' investment in biofuels may also cause new environmental and social problems. Because the growth of many biofuels requires the best land, abundant water resources and chemical fertilizers harmful to the environment, in order to manufacture biofuels, the land for crop cultivation and other production resources will be changed, and this change will pose a great threat to food production and supply. The study found that the demand for palm oil is currently rising rapidly. Affected by this, the tropical rainforest area in Southeast Asia has shown signs of reduction. In addition, the transfer of food crops to fuel crops will lead to rising food prices. Recently, the sharp rise in corn and sugar prices in some regions is an example
although the planting of biofuel crops will create more employment opportunities for people in poor areas. But to grow these crops on a large scale, farmers with small-scale planting land must free up their land. To this end, the report also recommends that governments or relevant institutions provide subsidies to farmers
previously, the United Nations also issued some reports on biofuels, but at that time, due to the lack of understanding of the negative effects of biofuels, food contact materials can only take the materials in the table during production, and the attitude of these reports is relatively optimistic. However, with some private sectors' crazy pursuit of the huge benefits that biofuels can bring, biofuels have increased the price of daily necessities, and people are alert to the shortage of water resources. Therefore, relevant people have also issued an urgent appeal
with regard to biofuels, the president of the United Nations Energy Organization, mats Carlsson, also said: "what fuel is easier to obtain than the fuel that can be produced by sunlight, water and photosynthesis alone? However, when you really want to expect nearly all aviation and space flights to adopt chemistry to drive them, you will find that you are actually facing great challenges."
