What happened to the earth
o
Look and discuss
1. Where do you think this photo was taken
2. What does this photo make you think of
I think this photo was taken in either the Arctic or Antarctica , as those places have large ice sheets like this .
The photo makes me think of the problem of global warming .
o
What is “Global Warming”
Watch and Discuss
1. What is the graph about What information can you get from it
2. Have you ever seen the photo before What might be the story behind it
o
What information can we get from the graph
The graph shows the change in the Global Surface Temperature between 1920 and 2016.
Temperature Anomaly(n.异常)
The Global Surface temperature is abnormal and rising.
o
Watch a video about what happened to the polar bear.
Discuss
Have you ever seen the photo before What might be the story behind it
The story is that the polar bear starved to death because it could not find enough to eat and even lose its habitat .

Earth provides enough to satisfy every man’s needs, but not every man’s greed.

Such as shelter, air, food, water and the means to do something productive and meaningful.
Greed is a desire that can never be satisfied.
Needs mean all basic living things
The quote is used here to suggest that consumption powered by greed is a prime cause of environmental degradation (环境恶化).
