Biodiversity at Risk

The fact that organisms are adapted to survive in particular environments helps to explain why

• captive-breeding programs are often ineffective.

• non-native plant species never flourish in new areas.

• habitat destruction accounts for most extinctions.

• compromise is impossible on environmental issues.

What groups of organisms are most in danger of extinction?

• those with small populations

• those that migrate or need special habitats

• those with large populations that breed quickly

• Both (a) and (b)
