Global climate change will have a greater impact on food production, the main reasons are as follows
Global warming is a phenomenon related to nature, which is due to the continuous accumulation of greenhouse effect, resulting in the imbalance of energy absorbed and discharged by the geo-atmospheric system, and the continuous accumulation of energy in the geo-atmospheric system, leading to rising temperature and global warming.
Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have strong permeability to visible light emitted by the sun and strong absorption to long-wave radiation emitted by the earth.
It can strongly absorb the infrared rays in the ground radiation, leading to the increase of the earth's temperature, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also affect human health and even threaten human survival.
Other causes of climate warming:
On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises and the temperature difference with the ocean decreases, which in turn leads to the slow air flow and the smog can not be dispersed in a short time, which leads to the increase of smog weather in many cities and affects human health. Measures such as car restrictions and production suspension have only short-term and local effects, and cannot fundamentally change climate warming and smog pollution.
