Final Exam #3

A renewable resource is a natural good that isnt in demand and is easy to replace.(1) Non-renewable resources are resources that are in high demand and are hard to replace like fossil fuels.(1) Water and wind are renewable because we can get really easy but something like oil or gas, we have to buy with alot of money from the goverment.(1) The earth's energy changes even with the slightest change, like if the ocean and wind currents pick up heat from tropics and moves it to the higher latitudes.(2) People today depend on gas for cars and electricity, which are both non-renewable resources. But gas can effect the envirment just by polluting the air and electricity could decrease the coal because we are burning it way to much. Gas helps us get to where we have to go but with the cost of gas it is horrible ($4.08) for people to keep on buying it.(2) This info will help us in the future because we won't have to spend so much on certain non-renewable resources that we don't need, even though some people will say that we can't live without certain things which is false.
