What words do you read when cutting and adding soil to the bottom? How to describe the reason and harm of felling trees
The situation of water and soil loss is seriously lack of oxygen supply and natural filter.
The ecological environment was forcibly occupied, and the ecological cycle law was destroyed.
The temperature will change, resulting in unstable changes in the climate.
After felling, the waste of trees will be burned, causing environmental pollution The forest is a carbon dioxide processing plant, which absorbs carbon dioxide and releases oxygen that is helpful to people.
The reduction of forests will inevitably lead to the reduction of oxygen supply.
Now the amount of oxygen consumed by human and human activities is increasing, so the reduction of forests will make life difficult.
Then there are natural disasters brought about by forest reduction, such as sandstorms, mud rock flows and other natural disasters that endanger human health and life.
In addition, the forest is a good place for summer vacation. At the same time, the forest can also reduce the air temperature.
The reduction of forests will exacerbate the greenhouse effect.
Chinese farmers account for about half of the world's population using firewood as fuel.
Due to the massive deforestation, there is a widespread shortage of firewood in rural areas in China. This situation makes farmers use all organic energy sources, such as straw, straw, wormwood, etc. as firewood, so that organic matter cannot be returned to the field, soil conditions deteriorate, and rural ecological balance is destroyed.
In arid areas, excessive logging will easily lead to desertification. Plants in arid and desert areas grow slowly. For example, in Qaidam, Qinghai, a plant of Ephedra equisetifolia with a diameter of 6 cm at breast height needs to grow for 50 to 60 years. Once cut down, these trees will be difficult to recover, and even become desert or Gobi.
However, due to the increasing demand for firewood due to population development, the number of felled trees has increased. Many natural drought and cold tolerant plants in arid desert areas are being consumed at an alarming rate or even extinct. Many areas in the northwest are rapidly desertification. If this phenomenon is not stopped, the consequences will be unimaginable.
