Lead-in
Earth provides enough to satisfy every man's needs, but not every man's greed.
---Mohandas K. Gandhi
地球能满足人类的需要，但满足不了人类的贪婪。
——莫汉达斯·k·甘地
莫罕达斯·卡拉姆昌德·甘地（1869年10月2日—1948年1月30日），印度民族解放运动的主要领导人之一，印度国民大会党领袖。
甘地出生在一个印度教家庭，父亲是当地土邦首相。甘地19岁时赴英国留学，研习法律。1893年前往被英国控制的南非，领导南非印度人进行反种族歧视斗争，并提出“非暴力抵抗”口号。1915年，甘地回到印度，在第一次世界大战后在印度倡导对英国殖民政府开展“非暴力不合作运动”。他长期领导印度国大党，在吸引农民参加民族运动方面起了重要作用。甘地主张印度教徒与伊斯兰教徒团结合作，并提倡社会改良及妇女和“不可接触者”地位的平等。20多年来，甘地在争取独立斗争中，先后绝食21次，被捕8次，坐牢时间约6年半。第二次世界大战后，印巴分治。面对两国的冲突，对双方都有重要影响的甘地多次以绝食来感化他们，呼吁团结。1948年，甘地遭到印度教顽固教徒刺杀。著有《印度自治》《我体验真理的故事》《甘地全集》。
甘地是提倡非暴力抵抗的现代政治学说——甘地主义的创始人。他一生身体力行实践着这一精神思想，带领国家迈向独立，脱离英国的殖民统治，被尊为印度国父。其“非暴力”的哲学思想，影响了全世界的民族主义者和争取能以和平变革的国际运动。后世尊称他为“圣雄甘地”。

The polar bear in the photo died of starvation. The writer wrote about it because it showed one of the effects of rising temperatures due to climate change.
The “natural” green house effect is important because it warms the Earth's surface and keeps it habitable.
High greenhouse gas emissions lead to more heat energy being trapped in the atmosphere and rising temperatures.

Draw a diagram
Diagrams are very useful tools that can be used to brainstorm ideas, map out processes, show cause and effect relationships, explain a new idea or concept, and so on. When you read an essay about scientific issues, you can try drawing a diagram, which will not only allow you to visualise the problems more clearly but also can help demonstrate your creative thinking and problem-solving.
图表是非常有用的工具，可以用来集思广益，绘制过程，显示因果关系，解释一个新的想法或概念，等等。当你阅读一篇关于科学问题的文章时，你可以试着画一个图表，这不仅能让你更清楚地想象问题，还能帮助你展示你的创造性思维和解决问题的能力。

Governments need to consider making policies and taking appropriate actions and measures.
We as individuals can reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce.

There are sadly many examples of extreme weather and disasters I know of, such as the extreme rainfall in France and the drought in East Africa in 2014. There were also heatwaves on nearly every continent due to climate change.
1 What examples of extreme weather and disasters do you know
Can you make a list
Discuss these questions in groups.

2 Do you think climate change is the result of human activity
Give your reasons.
Discuss these questions in groups.
4
I do think climate change is the result of human activities because the majority of scientists also think so, and also because global temperatures have followed the rise in global emissions and population.
Discuss these questions in groups.

3 Who do you think should take responsibility for dealing with climate change
What can we do
I think we all need to take responsibility for dealing with it. Individuals can change their behaviour and try to reduce their carbon footprint, while companies and governments can do the same on a larger scale.
