With the exponential increase of the emission of carbon dioxide after the industrial revolution, the averaged temperature of the world ascends dramatically. Besides, continuous deforesting and exploiting makes tropical rainforests vanish quickly in a large dimension, as accelerates the deterioration of this situation as well. Nevertheless, we human beings always consider that no matter what we do to the earth, it will tolerate in silence. Ignoring how detrimental it suffer, we take it for granted to consume the resource of the nature. However, the earth starts to retaliate. The problems such as glacier retreating, food insufficiency, the level of the sea rising surge lead to numerous animals losing their habitats, hundreds of millions of people under starvation, and millions of insular residents leaving their countries. To rescue our earth, it’s high time for us to do something.

Coal, natural gas, and petroleum which are widely utilized in this modern world to generate energy, simultaneously emit lots of greenhouse gas. To protect our earth we should look for some alternative energy. Water power is a good choice. With its environmentally-friendly tendency, it’s really a sustainable means not only to generate electricity but cut down on the output of greenhouse gas. Nuclear energy, the gradually predominant source of energy, can generate tremendous energy just with little material. Although it will subsequently make some nuclear waste, if we deal with it cautiously, it won’t do much harm to us. And the solar energy, the most potential type of energy, in my opinion, will someday replace traditional energy. Despite the low efficiency it turns solar power into electricity, scientists will make every endeavor to develop it in the future.

The tropical rainforests, or the so-called “the lungs of the Earth,” are vanishing at a high speed. Some developing countries, for instances, Brazil, cut down the forests excessively to plant economic crops such as coffee, or coconuts, and develop tropical agriculture. However, the fact is that every tree deserves to be well-protected, and why? This blessed place is the sanctuary of approximately sixty percent of spices of the world. It’s saturated with miscellaneous animals and vegetation, and the most important is that it plays a crucial part of reducing the amount of carbon dioxide, and that helps cool down the earth. So what can we do? We can choose the coffee planted at a low altitude, use the bowls and the chopsticks provided by the restaurant instead of paper-made or bamboo-made ones. And the most necessary is to cut down on the waste of papers. After all, the less we waste the paper, the fewer trees will fall down because of us.

As one of the dweller of the earth village, every person is obligated and destined to do something beneficial for the earth. We can’t change the world; however, we can alter ourselves. Maybe it’ll take us ten years, fifty years, or even longer to solve this problem. But with perseverance, nothing is insurmountable. It’s we human beings that determine what the world will become, a paradise, or a hell. So just wake up, let’s collaborate to save our home, our beloved, mutual home.
