Solar energy, air, and water are renewable resources because there is an unlimited supply However, this definition may be

changed if people are not careful with these resources The

amount of solar energy that reaches the earth depends on the

atmosphere If the atmosphere is polluted, the solar energy that

reaches the earth may be dangerous If life is going to continue,

the air must contain the correct amount of the air must contain

the correct amount of nitrogen (N), oxygen (O), Carbon dioxide

(CO2), and other gases If humans continue to pollute the air , it

will not contain the correct amount of these gases
