Earth's resources generally refer to natural resources.
Natural resources refer to the materials in nature that humans can directly obtain for production and life.
It can be divided into three categories, one is non-renewable resources, such as various metals and non-gold island minerals, fossil fuels, etc., which need to go through a long geological time to form; The second is renewable resources, which refer to biological, water, land resources, etc., which can be reproduced or recycled in a relatively short period of time; Third, inexhaustible resources, such as wind power, solar energy, etc., will not lead to a reduction in storage capacity after being utilized.
The central task of nature conservation is to protect, multiply (refer to renewable resources) and rationally use natural resources, so as to improve the ability of resource regeneration and continuous utilization, and seek the unity of environmental and social economic benefits.

Earth resources refer to: the earth can provide human beings with clothing, food, housing, transportation, medical needs of the material raw materials, also known as:"Natural resources"(natural resources)。
There are six important natural resources on land, which are: 1) freshwater, 2) forests, 3) land, 4) biological species, 5) mines, and 6) fossil fuels (coal, oil, and gas).
Mineral resources. The earth is a place for human beings to live in, a source of food and clothing. There are more than 3,300 known minerals on the earth and constitute a diverse mineral resource. More than 95 percent of the energy we use, more than 80 percent of our industrial raw materials, and more than 70 percent of our agricultural production materials come from mineral resources.
Mineral resources are generally divided into metallic minerals, non-metallic minerals, energy minerals, etc., and there are three forms: solid, liquid and gas.
The earth's resources are limited and non-renewable, and the excessive exploitation and unreasonable development and utilization of mineral resources will inevitably bring about the depletion of resources and the negative impact on the earth's ecological environment. The rational and effective use of the earth's resources and the maintenance of the living environment of mankind have become issues of common concern in the world today.
Mineral resources are known as the "food" and "blood" of modern industry, and are the lifeblood of the development of human society. Mineral resources are not only an important material basis for the survival and development of human society, but also the industrial foundation of the global economy.
Not only in the economic field, but also in the political field, mineral resources show their important value. Throughout the last century, there have been hundreds of wars, whether it was two world wars or the Gulf War, in addition to the contention for territory, the possession of various mineral resources has often become the fuse that triggers the outbreak of war. In order to ensure the security of the country in extraordinary times, many countries in the world have embarked on strategic reserves of mineral resources very early.

Background of the storyDecades ago, a song "Volga Boatman's Song" spread to China. Its touching melody and beautiful lyrics deeply tug at the heartstrings of the listeners. Since then, the name Volga has been deeply imprinted in the minds of Chinese.
Recently, however, news came that the Volga River, which the Russians call the "mother river," is so polluted that the water surface of some sections of the river is even covered with oil splashes, and the fish and shrimp in the river have died one after another, and the "mother river" is on the verge of "death." The Volga, known as Europe's largest river, originates in the Valdai Hills northwest of Moscow and winds southward, covering an area of 1.36 million square kilometers and a total length of 3,690 kilometers. It is like a large tree with flourishing branches, nourishing about 1 3 of the European regions of Russia, and 1 4 of the population of all Russia.
For example, the Volga River, known as the "mother river", has been having a hard time lately, and it receives nearly half of Russia's industrial wastewater. These effluents contain not only domestic waste, heavy metals and their compounds, but also radioactive substances, organic poisons and oils. As a result, the people in the Volga River basin are facing the crisis of water shortage.
Today, water pollution is already very serious. It is said that more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year, polluting 5.5 trillion cubic meters of fresh water, accounting for more than 14 percent of global runoff, and it is currently on a worsening trend. According to experts**, the world's sewage discharge will increase to 16000 2.1 trillion cubic metres by 2000, and water resources will be even more polluted.
Water pollution is a serious threat to human health. Domestic sewage often contains many deadly viruses, germs and parasites. Once this pathogen-containing sewage contaminates drinking water sources and enters the human body, it can quickly cause various diseases, such as dysentery, diarrhea, typhoid, hepatitis, cholera and other infectious diseases, which in turn lead to a large number of deaths.
Diarrhoea and other diseases caused by unsafe drinking water kill millions of children each year, according to a report from the United Nations Children**. Drinking water is contaminated with heavy metal ions and toxic organic matter, and the consequences will be even more terrible. Water contains various heavy metal ions and organic matter that are difficult to decompose, including phenols, cyanide, mercury, chromium, arsenic, lead, cadmium, etc., which are extremely harmful to the human body.
These substances can cause malformations, cancer, and organ lesions in people. Minamata disease and pain disease are the most typical examples of this.
