Answer key

Part A — the answers.

  1. Deforestation.
  2. Species diversity.
  3. A rain forest.
  4. Carbon dioxide.

Part B — the answers.

  1. About 15 percent.
  2. The weather.
  3. There are fewer plants to take in carbon dioxide and give off oxygen.
  4. In the living plants, not in the ground.
  5. Only a few years.

Part C — the answers.

  1. It's spent.
  2. Cut new forest.
  3. Any answer that works.
  4. Buy the land and keep it from being cleared.
  5. Another way to live.

Part D — what a good answer includes.

  1. Answers vary. A good answer says native people depend on farming and cutting the land to feed their families, the book compares it to the American pioneers, and any answer that works has to include them.
  2. Answers vary. A good answer gives one reason from either side: the forest matters to everyone, a poor country shouldn't have to give up its only income, the people who live there should decide, or the world should help them find another way to live.

A farmer has to be part of any answer that works. Copyright © NexEdge Studios
