Every inch of fertile soil is a complex organic system. In this system, the substances necessary for life rely on solar energy to cycle over and over again, from plants to animals, to bacteria in the soil, and back to plants. In addition to many other nutrient chemicals, carbon and nitrogen are the two basic …

In the process of oil drilling, extraction, refining, transportation and use, some oil will be lost to the surrounding environment, and some losses are unavoidable during the operation (see Figure 1). The recovery rate of oil in the ore vein is 30% when mining oil, and the recovery rate can reach 40% to 50% when …
Coal is the most abundant part of fossil energy, and coal is also the most serious energy source that pollutes the environment. Coal mining methods can be divided into open-pit mining and underground mining. Open-pit mining accounts for about 1/3 of the world, and underground mining accounts for about 2/3. Coal often coexists with methane …
A large number of fossil fuels such as coal and oil used by humans will produce many kinds of air pollutants during the combustion process. Combustion is considered to be the first source of air pollution. These air pollutants have harmful effects on human health and the environment. Air pollutants can be divided into primary …
The global environmental problem of the sharp decline in biodiversity is caused by human behavior, and it can also be regarded as a negative effect of energy use. It is estimated that in the late 1980s, the area of the tropical rainforest was being destroyed at a rate of two football fields per second. If …
Among the environmental effects of energy, in addition to toxic and harmful chemical pollutants, atmospheric greenhouse effect, radioactive substances, etc., thermal pollution is also a kind of ecological environmental pollution in the process of energy utilization. Thermal pollution refers to environmental pollution caused by waste heat emitted by humans in various production and living activities …
Acid rain has become one of the most serious regional environmental problems in the world today. From a broader perspective, the term acid rain can be extended to acid precipitation. Acid deposition means that the acid in the atmosphere migrates to the ground through precipitation (such as rain, fog, snow, etc.), or directly migrates to …
The average temperature of the Eurasian and North American continents will be 6 to 8°C higher than the current actual temperature. The current global daily average temperature on the ground has increased by 0.6°C compared to before the first industrial revolution. The scale of this temperature increase is equivalent to the temperature change that can …

At present, the concentration of CO2 in the atmosphere is increasing at an annual rate of 0.4% to 0.5%. According to meteorological data and scientists’ speculations, the concentration of CO2 in the atmosphere remained basically around 275×10-6 from 10,000 years ago to the early stages of the Industrial Revolution. After the Industrial Revolution, the concentration …
British geochemist E. Hamilton and others found that the content of more than 60 chemical elements in human blood is related to the content of these elements in the earth’s crust through blood analysis of human organs. Harmony and unity of human material. In the final analysis, human beings are the product of the long-term …
