Global Warming. Carbon dioxide. Methane. Nitrous oxide. We are responsible for greenhouse effect. Smoke from vehicles. Increase in level of carbon dioxide. Smoke from factories. Increase in level of greenhouse gases. Trees absorb carbon dioxide. Maintain carbon dioxide balance in the atmosphere. However, human beings are cutting trees for roads and buildings leading to deforestation. Deforestation. Carbon dioxide balance is not being maintained. Thicker. Layer of greenhouse gases is becoming thicker. The thicker layer of greenhouse gases traps more heat. Greenhouse gases trap heat. Increase in average temperature of earth. Disease Global Warming. The thicker layer of greenhouse gases traps more heat. This result in an increase in average temperature of the earth and the earth becomes hotter and hotter. This is called global warming. If we do not take steps to reduce global warming, it will lead to loss of human lives, plants and animals. Steps to reduce global warming. Plant more trees. Reduce, reuse and recycle. Use less hot water. Turn off electronic devices when not in use. Spread awareness. Come on everybody, let us reduce global warming. The End.
