Green House, is a space enclosed with plastic material which is hotter than surroundings. Such green houses are developed to grow specific plant species that can sustain hot climate only. Green House gases do the job of keeping Green House warm. Carbon Dioxide (CO2), Water Vapors, Methane (CH4), Nitrous Oxide (NO2), Chloro Fluro Carbon & Ozone (O3) are Green House Gases..

Green House gases can trap the heat between their molecules. They are not good conductor of heat. Hence heat is captured like thermos in them for longer time. They absorb Infrared Radiation which causes them to trap heat.

Green House gases also play an important role to keep our globe in proper temperature, which is sustainable for species living on it. Hence during Night, temperature don’t drop from specific value.

However for last few decades, due to rapid growth of industry, content of Green House gases is increasing in atmosphere. This is trapping more heat in the atmosphere and increasing temperature of Earth. It is not good for Earth to have more temperature than normal limit. Increased temperature has melt glaciers in polar regions and caused extinction of few species.

Green House gases like Chloro Fluro Carbon (CFC) are harmful for the ozone layer. Ozone layer is a protective layer above the surface of earth which blocks harmful Ultra Violet radiation coming on Earth. CFC react with ozone and cause depletion of it. This adds even more heat and radiation on the Earth.

Increased content of Green House Gases has become potentially dangerous problem for our future and existence on Earth. We need to prevent it as soon as possible.
