1.10 Australia's natural resources

1. Resources are any materials that can be used by humans.
2. Living resources, such as trees and fish, are renewable sources as they can be reproduced within a human lifetime. Non-living resources,such as coal and oil, are non-renewable as they take thousands or even millions of years to form and cannot be reproduced within our lifetime.
3. Renewable resources can become non-renewable through over-exploitation.
4. Healthy soil is a necessary resource as it is the basis for Australia’s agricultural industries. Soil is also important in the water cycle.
5. Silviculture in the dictionary is the branch of forestry dealing with the development and care of forests.
6. Australia has nearly 1.7 million square kilometres of forest.
7. Australia’s fishing and aquaculture industries are worth more than $2 billion.

9. Australia is has the largest resources in bauxite, iron ore, lead, zinc, silver, uranium and some mineral sands.
10. Australia's demonstrated reserves are increasing because of improved technologies. 
11. Australia's forests cover over 164.4 million hectares of land. That means that a forest per person is 8.2 hectares. The Native forest area covers 162.7 million hectares while the Plantation forest area covers 1.7 million hectares. 
12. Uranium is a valuable resource because scientists figured out that it release's huge amounts of power. Uranium can also be used for nuclear weapons and is worth a lot of money.
