Man-made Causes
Man-made causes probably do the most damage. There are many man-made causes.1is one of the biggest man-made problems. Pollution2in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil(化石) fuels(燃料)are fuels made of organic matter such as coal, or oil. when fossil fuels are burned they3a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane(甲烷)is4in the ground.5coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.
Another major man-made6of Global Warming is population. More people7more food, and more methods of transportation, right? That means more methane because8will be more burning of fossil fuels, 9more agriculture. Now you’re probably thinking, “Wait a minute, you said agriculture is going to be damaged by Global Warming, but10you’re saying agriculture is going to help cause Global Warming?” Well, have you11been in a barn filled with animals and you smell something12? You re13methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem14the increasing population is15. More people means more cars, and more cares means more pollution. Also, many people have more than one car.
Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2.16, the trees that change our CO2 to oxygen are being demolished because we’re using the land that we cut the trees down from as property17our homes and buildings. We are not replacing the trees(an important part of our ecosystem), so we are18taking19of our natural resources and giving nothing back in20.
