1.10

1- Resources are any materials that can be used by humans
2- Most biotic or living resources, such as trees and fish, are renewable as they can be reproduced within a human lifetime. Abiotic or non-living resources, like coal and oil, are non-renewable as they take thousands or even millions of years to form and therefore cannot be reproduced within our lifetime.
3- Renewable resources can become non-renewable through over-exploitation.
4- Healthy soil is a vital resource that is the basis for Australia's successful agricultural industries. Soil is also influential in the water cycle.
5- the branch of forestry dealing with the development and care of forests
6- 164.4 million hectares
7- They are very valuable and worth more than 2 billion dollars
8- An example of protecting fish species is that only 5265 tonnes of tuna are allowed to be fished each year.
9- Uranium
10- They are increasing due to improved prospecting and extraction 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.  
13- World heritage sites are valuable resources because they attract tourists.
14- I think mining for Uranium would disfigure the Earth and Landscape
15- Australia's fishing zones are basically all surrounding the country.
