The fact about environmental protection 1.2020, the sudden COVID-19 epidemic caught us off guard. Hunting, trading and eating wild animals are just one aspect of human crazy attack on nature and greedy expansion of the boundaries of human activities. We have experienced such consequences for a long time, but it is a pity that many people have healed their scars and forgotten the pain, so that today, 17 years later, 654.38+04 billion people are thinking behind closed doors! Without learning from the previous teaching of trout, today's tragedy has become. Similarly, for other aspects of the natural environment, we can't ignore the lessons learned from wildlife and let the tragedy repeat itself! The performance of human beings' crazy attack on the air is that a large amount of exhaust gas from factories and motor vehicles is discharged into the air, which makes people unable to breathe and causes various respiratory infections, including lung cancer. It affects the growth of crops, leading to the extinction of some plants and the reduction of grain production. It will also change the climate and directly threaten the survival of mankind. Water pollution, including lakes and oceans. A lot of harmful substances produced by factories are piled up or buried, and the land will be seriously damaged. The harm these environmental damages have brought to human beings now seems to be alarmist, but who predicted the epidemic that closed 654.38+04 billion people? We need a certain degree of foresight in case of emergency, rather than "cramming for the Buddha's feet". Large-scale environmental control requires the promulgation of laws and regulations at the national and government levels and the implementation and supervision of relevant departments, and individuals are not idle. We can use less plastic bags, do not use phosphorus-containing washing powder, do not burn plastic debris, and strictly require ourselves to sort garbage and so on. These are all things that individuals can do to protect our planet. -"Butterfly Change Composition"
Global warming and urban "heat island" Global warming will cause changes in precipitation, dry and wet conditions in various regions of the world, and then lead to changes in the economic structure of countries around the world. Mid-latitude areas will become dry due to the intense evaporation caused by climate warming, and now the developed agricultural areas will degenerate into grasslands; High latitudes will increase precipitation due to warming, and temperate crops will be able to settle here. But from a global perspective, the negative impact of climate warming on the world economy is major, and only local areas benefit. The temperature in the city is much higher than that in the suburbs, like a warm island. Beijing, the largest city in China, is 9.6 degrees higher than its suburbs, and the maximum temperature difference between Shanghai and its suburbs is 6.8 degrees. The reason of urban "heat island" effect is that the urban population is concentrated and increasing, and the factories are increasingly developed, releasing a lot of artificial heat. Another reason is that urban roads are covered with primitive vegetation, with low reflectivity and large heat capacity, which absorbs a lot of solar energy. -"Butterfly Change Composition"
