Question 3
3.
To survive and advance, humans have used the natural resources in their environment for at least as long as recorded history. Some of these are renewable, like the wood from a forest. Some natural resources are not renewable, like oil pumped out of the ground. This is because we can use the wood from the forest and plant trees to replace what was taken. With oil, we cannot replace what we have used. When it is gone, it is gone for good.
What is another example of a resource that has a limited supply?

Question 6
6.
Over the last several decades scientists have considered the problem of nonrenewable natural resources, such as fossil fuels. Humans are using fossil fuels at a rapid rate and scientists believe that one day, we will run out of usable fossil fuels. To solve this problem, research has been conducted on alternative energy sources. One alternative energy source is wind energy. Although wind energy is a good solution to this problem, it is not the perfect solution.
