Câu trả lời: It is now almost certain that global warming has been directly caused by man's use of fossil fuels. This has led to an international debate about what we should do to reduce the negative effects of our actions and how we can make the planet safe for our children to live in. One consequence of this debate has been to improve the level of "green" education in schools and this should result in greater awareness of the difficult issue in the long term. However, in the short term there still remains much to be done. The reason for this is that we need to address causes of the immediate problem.
