背后有多大的利益集团不敢触碰?再这样下去,中国人都死绝了,还复兴个鸟啊?
科学家他们正在忙着解释原因,已有成果:
所以其实美帝他们既没饭也没车的。。。
我一个朋友说,他老家的一个朋友请他回去投资化工厂,只需要10w块,买个锅炉开始烧就行了,老家已经遍地都是了,置于污染不污染就只能呵呵了,他老家就在某个大城市不远的某个省里。
不说具体地点了,免得地域攻击
Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of particulates. Coal combustion in developing countries is the primary method for heating homes and supplying energy. Because salt spray over the oceans is the overwhelmingly most common form of particulate in the atmosphere, anthropogenic aerosols—those made by human activities—currently account for about 10 percent of the total mass of aerosols in our atmosphere.
