The Extinction Crisis:
1. What is human use of the Earth’s resources causing?
→ Mass extinction.
2. In your own words, what will happen if humans continue to destroy, degrade and
fragment the habitat?
→ Total ecological collapse.
Why it Matters:
3. Human populations depend on plants and animals for much of their
4. Intact ecosystems perform many vital functions- list 3.
1 Purifying air.
Filtering water.
Preventing erosion and flooding.
Threatened and Endangered Species
5. When is a species or subspecies regarded as “endangered”?
→ When it is in danger of extinction.
6. When is a species considered “threatened”?
→ When it is likely to become an endangered species in the near future.
The Causes of Extinction
Habitat Loss
habitat loss
7. The most common cause of endangerment is ____________________________.
8. Give an example of how the increase of human population and consumption affects
wildlife habitat.
→ As human population and consumption increase, wildlife habitat is converted to houses and highways. Forests are cut down for building materials,
fuel, and paper.
The Causes
Introduced Species
9. What happens when humans move and introduce species to non native ecosystems?
→ Disrupting the delicate balance that evolved among species in that ecosystem.
10. What do the introduced species compete with native species for?
→ Food and/or nest sites.
11. How are non-native species transported?
→ By roads and by sea.
The Causes
12. List at least 5 things that animals are killed and used for.
→ Food, fur, feathers, oil, crafts, and more.
13. What is a huge and growing cause of wildlife endangerment?
→ The international market for animals and animal parts.
The Causes
14. Which species are especially vulnerable to pollution and why?
→ Fish, frogs, marine mammals, and many invertebrates. They're all creatures that depend on either freshwater or saltwater for all or part of their life
15. What are some ways that water is polluted? (List at least 4)
→ Run-off of fertilizers and pesticides from farms, oil and other chemicals from roads, human sewage that flows untreated into rivers, lakes, and
oceans, and dumping waste in general.
The Causes
Other Factors
16. What are the natural and nonthreatening phenomena in many ecosystems?
→ Disease and insect infestations.
