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