1. Using Figure 8.2, find the biome you live in. Using Figure 8.28, can you tell what its leading category of human land use is now?

2. Many people in Brazil claim that other countries such as the United States have no business telling Brazil not to cut its rainforests because most developed countries (such as the United States) cut their forests early in their histories. Do you agree or disagree with this argument? Explain.

3. Most tropical rainforest canopy trees have a flat, umbrella-like structure. Most boreal forest trees have a narrow, pole-like structure. In the context of solar altitude (see Section 2.1), explain the structure of these trees.

4. Non-native species are often most successful when they are transported to the same or a similar biome. They are less successful if they are transported to a different biome. For example, many invasive plants in California came from the Mediterranean region. Why do you think these plants have been able to successfully establish in California?

5. Besides helping people, can you think of other reasons to save habitat and species?
