Without
the greenhouse effect the Earth would be colder than it is today. It is letter
C. Greenhouse effect is a social/environmental/global problem where the gases
from CFCs, carbons, etc accumulated to the earth’s stratosphere causing
pollution and trapped heat. Green house
is one of the ways people could avoid greenhouse effect. In making your house
green, that is making it plant-friendly, you will be breathing more oxygen,
less carbon dioxide. Thus if there is no greenhouse effect, there is colder
atmosphere since the heat is not trapped on the Earth’s atmosphere.
