The Greenhouse Effect

           Greenhouse effect is caused by industrial pollution. Because of the effect, the temperature of the Earth increased. According to the data taken by scientists, our Earth has been warming up since the Industrial Revolution. 

            Why does it happen? Emissions from the factories' have created smog in the atmosphere. The Earth's atmosphere becomes like a greenhouse, and the Earth and everything inside of it have 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.
