How does dumping industrial waste in the soil affect the environment?
The harmful chemicals, which are suspended in the air, get dissolved in rainwater and pollute the soil when they come to the Earth’s surface in the form of acid rain.
What is the most important environmental problem?
Air Pollution . Air pollution is one of the major environmental problems in the world. The United States, which constitutes for approximately 5 percent of the world population, alone produces 25 percent of the total carbon dioxide in the world. Among the leading causes of air pollution, human transportation is by far the most prominent.
Is pollution a natural or man-made problem?
While pollution is caused by natural as well as man-made sources, it is the man-made pollution which is adding to the severity of this issue and threatening the existence of life on the planet. To a large extent, environmental pollution can be attributed to various human activities, such as transportation, industrial production, construction, mining, agriculture, etc. These activities, which are technically referred to as the anthropogenic causes of pollution, have been polluting the environment since ages. However, the rate at which pollution is happening today, we are left with no option but to take a serious note of it.

What is the destruction of land as a result of human activities and the misuse of land resources?
3. Land & Soil Pollution. Land pollution is the destruction of land as a result of human’s activities and the misuse of land resources. This occurs when humans apply chemicals such as pesticides and herbicides to the soil, dispose of waste improperly, and irresponsibly exploit minerals through mining.
