Fifty years ago green was just a colour. Now it's a way of looking at our world. But how green is our planet today?
From Rainbow Warrior to Exxon Valdez, from penguins to jaguars, from rainforests to oceans, this book explores the stories that have made environmental history.

Green Planet

2. Write the summary of the book.
On 31 December 1831, HMS Beagle left England on a five year journey to South America and the Pacific. On the Beagle was a young man called Charles Darwin. The Beagle spent five years travelling places In South America and the Pacific, and Darwin looked carefully at the animals and plants in all these different places.
At this time, most scientists believed that species did not change. They thought that from time to time a big change happened on Earth, and then the old species died and new species took their place. So an old fossil and a new species could not come from the same family. But Darwin began to think that perhaps this wasn't true.
After he came back from his travels, Darwin spent a long time studying, reading and writing about his ideas. Finally, in 1858, Darwin's book The Origin of Species arrived in bookshops. Darwin said in his book that any species could change over time into a new species.
These days most people think that Darwin's idea was right. Since Darwin's time, we have learnt that animals, plants, people and the environment are changing all the time.

3. Write your feelings about the book in details.
In 1900 there were 40,000 tigers in India; in 1972 there were less than 2,000. ....Ten years later, there were 4,000 tigers in India-twice as many as in 1972(See p 50).

The number of animals can change quickly and we should take care of them.

4. Write the words, phrases or sentences that impressed you most in the book and explain why they impressed you. Or you could write your questions about the book.

But since 1900 the number of people has grown more quickly; 2.5 billion in 1950, 5 billion in 1987, and 6 billion in 1999. By 2050 how many people will there be? (See p 26)

How on earth should we do to deal with this problem?
