Global warming is a problem increasing rapidly because of unsustainable development doing by developing countries of this world. Humans are just involved in developing without thinking about the future. Everyone is cutting down trees for timber, paper and for infrastructural development of commercial and residential places. Trees helps a lot in absorbing CO2 and other green house gases. Trees also helps in reducing the temperature where they are. Due to vigorous use of air condition and refrigerators a lot of CFCs is emitted in environment. This CFC which when come in contact with sun light, Chlorine get separated from it. Each atom of Chlorine reacts with ozone and breaks ozone into oxygen. This results in depletion of ozone layer. Ozone layer is basically a blanket of a gas that surrounds earth. It saves earth from harmful radiation of the earth. This UV rays which when fall on earth not only results in skin cancer, eye problem and ageing of skin but global warming also. Vehicles running on roads are increasing vigorously. These vehicles require petroleum products. When these petroleum products burn, a lot of Sulphur oxidants and Nitrogen oxidants are released in atmosphere. Along with these oxidants a lot of CO2 is also released. All these gases are green house gases which leads to global warming. The CO2 released in atmosphere forms a blanket around earth and does not let the heat go outside the atmosphere of the earth. A lot of uranium is used by many countries for making atom bomb and to generate electricity also results in global warming. To overcome the problem of global warming many countries came in frontline and signed a treaty named Paris climate agreement. In this agreement countries proposed to reduce the emission of green house gases in the environment.
Government should try to enhance the use of renewable energy resources like solar, wind and water energy. To reduce the emission of Sulphur and Nitrogen oxidants, electric vehicle should be increased. Every countries should try their best to reduce the emission of green house gases. Use of CFC based refrigerators and air condition should be reduced and new substitute should be developed which harm the environment less than CFC.
