Write a paragraph on 'Global Warming'.

The term 'Global Warming' refers to the rise in the temperature of earth. Nowadays global warming has made the environmentalists think about the dreadful consequences. It has become a threat to all living beings on earth. Global warming is caused due to greenhouse effect. Greenhouse effect is the gradual warming of the air because of heat being trapped on earth. Environmental pollution is mainly responsible for greenhouse effect. We are destroying our tropical rain forests, growing industries and mills-factories, and using CFC gas. Thus, we are polluting our environment. By the destruction and burning down our forests, the amounts of carbon dioxide are increasing. The increased amount of carbon dioxide around the earth has made a layer in space. The sun rays are coming through the layer but the heat cannot pass through that layer. This is why, the heat is being trapped on earth and making our globe warmer. As a result, the temperature of the world is increasing day by day. Effective measures should be taken by the world community to control global warming. Emission of carbon dioxide should be reduced. Deforestation must be stopped and more trees should be planted. We need a green environment because it helps clean the air, provides oxygen, and supports all forms of life. It also reduces pollution, preserves natural resources, and ensures a healthier planet for future generations. If we fail to stop global warming, the future may see more extreme weather events, such as intense storms, heatwaves, and rising sea levels. This could lead to widespread environmental damage, loss of biodiversity, and severe impacts on human health, food security, and economies.
