17. Discussion--1 1.Take public transit whenever possible. 2.Do not turn the air conditioners on when the degree is under 25. 3.Use things which can recycle again and again. 4.Plant more trees. Being a junior high school student, what can we do?

18. Discussion--2 A: About these questions, there are two different thoughts, one of them is yes, butyes the other one is no. But according to theno scientists, our Earth is really warming. Q: Is the world really warming up? Is the warming really caused by the human activities? And Should we worry about it?

19. Yes. It has become clear that the world is warming up slowly. According to the U.S. Environmental Protection Agency, the earth has warmed by about one degree Fahrenheit over the past100 years. What is less clear is that what is causing global warming– and what we can or should do about it. Some believe the warming is simply part of the worlds natural climate cycle. If the warming is natural, then there may be little humans can do to stop it. We may just have to learn with warmer temperatures. Discussion--2

20. No, our Earth is not warming up by human activities. As you can see, the Earth is still very lively, and the weather had changed since millions years ago. The ice age had came and gone for many times. There is no need to worry about our Earth. If the Earth is really warming up, it is just because the Heat Island Effect, not the Carbon. Discussion--2

21. Conclusion American writer Mark Twain once said, Everybody talks about the weather, but nobody does anything about it. Now, people really are trying to do something about it. Though we are just junior high students, we still can influence the people around us. From now on, we should do more to save our earth. Its not difficult for us to do it. Just do it!
