2. Forests are a resource because they contain valuable materials

3. Managing Forest
Because new trees can be planted to replace trees that are cut down, forests can be a renewable resource

4. Managing Forest There are two major methods of Logging Clear Cutting
Selective Cutting

5. Logging Methods
Clear cutting is the process of cutting down all the trees in an area at once

7. Advantages and Disadvantages to Clear cutting
1. Quicker and Cheaper
2. This method is safer for loggers
Disadvantages
Causes damage to the environment and the animals that live there.
After clear-cutting, the soil is exposed to wind and rain which causes erosion. (Without the protection of the tree roots, the soil is more easily blown or washed away.)

8. Logging Methods
Cutting down only some trees in a forest and leaving a mix of tree sizes and species behind is called selective cutting

10. Advantages and Disadvantages to Selective cutting
1. Less impact on the environment
2. Lower rates of soil erosion
Disadvantages
Takes longer and cost more money
. Increased danger for loggers. The loggers must move the heavy equipment and logs around the remaining trees in the forest.

11. Sustainable Forestry
A sustainable yield is a regular amount of a renewable resource such as trees that can be harvested without reducing the future supply.

12. Fisheries
An area with a large population of valuable ocean organisms is called a fishery

13. Managing Fisheries
Managing Fisheries for a sustainable yield includes setting fishing limits, changing fishing methods , developing aquaculture techniques and finding new resources

14. Fishing Methods Today fishing practices are regulated by laws
