The greenhouse effect is caused by industrial pollution.
Because of the effect, the temperature was increase. According to the taken by
scientists, our earth has been warming up since the Industrial Revolution. Why
does it happen? The emissions from factories have created smog in the
atmosphere. The earth’s atmosphere becomes like a greenhouse, and the earth and
everything inside of it has become like the plants in a greenhouse. The
sunlight can pass through the ozone layer but the heat transferred by the sunlight
cannot escape easily from the layer of smog and is deflected to earth’s surface
again.
