Land is the most basic natural resource, the fundamental means of production of agriculture, the storage of minerals, the place of human life and production activities, and the habitat of wild animals and China's animals.

Human survival can not be separated from the three basic elements of air, water and food. Usually, air, water pollution and ecological damage can be intuitively shown, easy to attract people's attention, but land pollution because of its hidden and retention characteristics, easy to be ignored in the short term. Once it breaks out, its harm will be ten times or even hundreds of times more serious than air and water pollution.

What are the hazards of land pollution?

， Land pollution will lead to the pollution of crops and reduce production. As a result, serious direct economic losses will be caused.

， Land pollution leads to the continuous decline of biological quality. The land near most cities in China has been polluted to varying degrees. Food, vegetables, fruits and other foods contain harmful ingredients, which will affect human health.

， Deforestation leads to thinning soil in mountainous areas, which is easy to lead to desertification, debris flow, haze and other natural disasters.

， Land pollution will lead to other environmental problems. After the land is polluted, the concentration of heavy metals is high, and the surface soil is easy to enter the atmosphere and water body respectively under the action of wind power and hydraulic power, resulting in air pollution, surface water pollution, groundwater pollution and other secondary ecological and environmental problems such as ecosystem degradation.

Then, how should we protect the land?

， Use less plastic bags, disposable foam plastic lunch boxes, do not throw away batteries.

Plastic bags and foamed plastic lunch boxes will cause white pollution, waste batteries contain a large number of heavy metals, will cause heavy metal pollution of the land.

， Do not take soil at will, do not cut down deforestation, and plant more trees and grass.

Deforestation is the main cause of land loss. If we go to the roadside, hillside, grassland and other wild land to dig soil, not only destroy the original vegetation, but also take away the surface soil, in the rain and wind wash will be more and more large, resulting in grassland degradation, serious will cause mountain debris flow, landslide and other malignant ecological events.

， Agricultural planting as little as possible to use chemical fertilizers, pesticides, more farmhouse manure.

Chemical fertilizers and pesticides will remain on fruits and vegetables, and if they are not cleaned, they will affect human health. At the same time, pesticides will change the soil quality, resulting in a decrease in yield and affect the economic ecology.

， Reasonable treatment of industrial waste

Factories should be reasonable treatment of industrial waste, the chemical residue in industrial waste will pollute the land, thereby polluting the nearby water quality, leading to ecological pollution, so can not be thrown away at will.

， Improve the awareness of soil protection.

It is everyone's duty to protect the land. In raising their own awareness of soil protection, at the same time, to the surrounding family and friends to promote the importance of land protection.
