Global warming, a natural phenomenon,has been a heated topic in recent years. Global warming will redistribute global rainfall, make glacier and permafrost melt and sea level rise, which not only does harm to the balance of natural ecosystem, but also threats human's food supply and living environment. It's interesting that global warming is bad for some places but good for other regions. For example, because temperature in cold areas in Antarctic and Arctic goes up, glacier will melt, thus making the habitat of animals decrease. While in the northeast of China, becoming warm means being able to plant grains of winter, thus raising agricultural revenue.
