The greenhouse effect is a natural phenomenon that allows us to live on the Earth, but with all of our traffic for transportation and coal-burning for electricity, we are causing the amount of heat trapped within our atmosphere to increase, causing the surface temperature of the Earth to increase, which causes our polar ice caps to melt.
