What is a 'Sustainable Resource'?
A Sustainable Resoruce that will not run out because its being produced, just as fast as its being used.
1 of 14
Why have Organisms become extinct/endangered?
Climate Change, Habitat Destruction, Hunting, Pollution and Competition.

What is 'Sustainable Development'?
ISustainable Development is managing a resource so that it does not run out. It provides the needs of an increasing population without harming the environment. Sustainability requires planing and cooperation at local, national, international levels
3 of 14
How can Endangered Species be conserved?
They can be conserved by Protecting Habitats, Legal Protection (prohibiting hunting), Education Programmes, Captive-Breeding Programmes, Seed Banks and also by creating artificial ecosystem.

What commercial value do dead and living whales have?
Living Whales cause a big tourist attraction. Dead Whales can be used for food, oil and cosmetics.
5 of 14
What are the issues arising in regards to keeping whales in captivity?
Whales are used for research or in captive-breeding programmes. But sometimes for our entertainment. People object because whales lose their freedom
6 of 14
Why are certain whale species close to extinction?
Some whale species are close to extinction because they becone entangled in fishing nets and drown. They're affected by the pollutants in the sea. They're colliding with ships during migration. The effect of climate change affects their food sources*
7 of 14
What aspects of whale biology do we need to know more about?
How whales communicate over large distances. How they migrate. How they dive and survive at extreme depths.
8 of 14
What are the issues concerning whaling?
It is difficult to police all of the world's oceans. It is difficult to enforce laws in regards to whalings, because it lacks international agreements. Some people still carry out hunting for research.

How do Conservation Programmes play an essential role?
They protect human food supply - maintaining the genetic variation of crops,animals and plants. They stabilise ecosystems - ensure that minimal damage is done to food chains. They study and identify plants - useful to develop medicines. They protect*
10 of 14
Why are species at a risk of extinction if there is not enough genetic variation?
If there is not enough genetic variation, species are at a risk of extinction because if the organisms were genetically very similar, if a disease killed one of them. it may kill all of them.
11 of 14
Explain how fish stocks and woodland can be sustained and developed?
It could be developed and sustained by educating people about the importance of quotas. Fishermen have to set by the quotas because without them, there will not be enough fish for the future generation. **

How does 'Sustainable Development' protect endangered species?
Sustainable Development
13 of 14
How do you evaluate a given example of a conservation programme?
Genetic Variation of key species. Viability of populations. Availability Habitats. Interaction between species.
