1.Soil erosion on the Loess Plateau.
In addition to some natural causes, the main human causes are the irrational use of land by human beings, the destruction of ground vegetation and stable terrain, and the rapid population growth leading to acute contradictions between man and land.
2.Desertification of land in the northwest.
Human activity. The pressure of population growth on land is the direct cause of land desertification. Overgrazing, extensive management, blind reclamation, irrational use of water resources, excessive deforestation, and irrational mining in arid land are the main manifestations of accelerated desertification expansion of human activities.
Indiscriminate digging of Chinese medicinal materials and deforestation are human activities that directly lead to land desertification. In addition, irrational irrigation methods have also caused secondary salinization of cultivated land.
Geographical and climatic factors.
Arid and semi-arid and sub-humid arid regions are located deep in the hinterland of the continent and are the most arid and fragile environmental zones with the least precipitation, the largest evaporation and the same latitude in the world. Desertification develops when the climate becomes drier, and when the climate becomes wetter, desertification reverses. In recent years, sandstorms that frequently occur in northwest China and north China (north) have aggravated the desertification process in these areas.
In addition, there are also things like the degradation of wetlands in Northeast China and the salinization of land in North China.
Hope it helps you, huh.

The plant arbitrarily emits exhaust gases into the atmosphere.
Cause. No exhaust gas treatment and so on.
Logging: Wood is used for processing as industrial and domestic materials.
Such as the tables and chairs you use, furniture, wooden floors.
Garbage: No one wants to spend a lot of money on garbage.
Humanity is not yet that rich.
Hunting: It's no longer for a living, it's for things like fur on animals.
There are also those that have been exterminated because some animals disturb the living environment of humans.
Industrial: Needless to say.
This is the foundation of human development to the present.
Clothing, food, housing and transportation are inseparable from industry.
It causes a cascade of environmental destruction.
from wood. Mineral resources. Arrive. Air.
Water. Even climate and geology.
All have a big impact.
