B
It's getting hot, isn't it? The temperatures are increasing all over the world. Recently, there have been extreme heatwaves in Europe, causing fires in Russia. It is also found that the glaciers (冰川) are melting in the North Pole (北极). All of these have to do with global warming.
Global warming is a result of the greenhouse effect. Earth is surrounded by the atmosphere (大气层). One of the important roles of the atmosphere is to catch some of the sun's energy in order to keep Earth warm. In fact, this is the greenhouse effect. The problem is that the development of technology in the last 100 years has increased the greenhouse effect to the point that it threatens (威胁) the life on Earth.
Only in the last few years, this problem has got the public attention. People care more about the present than the far future. But this problem has developed to such a point that it has to be faced now.
There are many things that can be done in order to solve this problem. At the personal level, we should use only environment-friendly products. At the national and international levels, countries should invest (投资) more in developing renewable (可再生的) energy sources, such as biofuel and solar energy.
