The problems that can be caused by moneyOne of the problems involved with money is worsening people's greediness, especially to the poor.First of all, the polarity between rich and poor makes money more appealing to the latter group. There are adequate historical examples that proved this point, including disputes between siblings and marriage ruptures between couples. Thus, it is fair to say that money somehow brings out one of the seven sins- greed- in human natures.Second of all, when it comes to money earning, some people tend to become irrational without knowing when to stop. Again, greed plays a part in this human weakness. For example, the poor will be more likely to throw all eggs in one basket by gambling in the casino. For another, some low wage earners sacrifice their health by doing several part-time shifts in a single day.To sum up, money itself is not dirty. People tend to make it dirty. Money, in many cases, can make people feel insatiable.

use of fossil fuels在climate change的人为因素中应该算是直接原因了, 我觉得比较深刻的根本原因是人类对经济发展的贪欲（贫富差距希望被缩小、发展中与发达国家的征逐、高速发展的现代科技...），就像高二地理书里讲的，环境问题的根本原因不是别的，而是人口和贫穷问题。可以表达一些属于你自己的观点，才会让文章显得比较出彩。然后再引出你觉得“use of fossil fuels”是一个比重很大的factor，怎么怎么样……（本人没写过1000多字的essay，想法仅供参考）
