1. Destroying the environment will lead to sandstorms, sediment loss, land reduction and ecological imbalance.
Large-scale concentrated rainfall is the primary cause of the Yangtze River flood. However, this year's precipitation is not the largest in history. So far, the total flow of the Yangtze River in flood season is only 20 billion cubic meters, far less than the 654.38+000 billion cubic meters in 1954. However, the water level in many areas of the Yangtze River has reached the highest level in history and has remained high for a long time. This shows that there are other more important reasons for the flood.
2, the ozone layer is getting thinner and thinner, carbon dioxide can't carry out photosynthesis, oxygen is reduced, and carbon dioxide is increased.
The role of trees is to produce oxygen, reduce carbon dioxide and dust, purify the air, make organic matter, solidify soil, make chemical raw materials, prevent wind, cool down and transform inorganic matter, so they are indispensable producers in the biosphere.
3. Loss of water resources
An acre of forest land stores 20 tons more water than an acre of forest land. The current situation of forest resources in China is as follows: forestland area is 263.295 million hectares, forest area 15894. 10000 hectares, and national forest coverage rate16.55%; The total standing stock is 65.438+0.249 billion cubic meters, and the forest stock is 65.438+0.65438+0.27 billion cubic meters. Except Taiwan Province Province, the national plantation area is 46.667 million hectares, and the plantation stock is 65.438+0.0 1 100 million cubic meters.
Deforestation fines:
According to the statistics of FAO,120,000 hectares of forests disappear every year in the world, which means that 20 hectares of forests disappear every minute on average. The areas where forests in the world have fallen sharply are all in developing countries. Because of poverty, they have to exchange precious forest resources for foreign exchange.
I. Punishment
Whoever unlawfully and wantonly cuts down forests or other trees in national nature reserves shall be given a heavier punishment.
Second, the filing standards
According to the provisions of the State Forestry Administration and the Ministry of Public Security on the jurisdiction and filing standards of criminal cases of forest and terrestrial wildlife, the starting point of deforestation or other trees is 10 cubic meter to 20 cubic meters or 500 young trees to 1000; Deforestation of more than 50 cubic meters of trees or more than 2500 young trees is a major case; Deforestation of more than 65,438,000 cubic meters of trees or more than 5,000 young trees is a particularly serious case.
