ROLE OF HUMAN ACTIVITIES IN GLOBAL WARMING

Global Warming :- 

Global warming is the cumulative rise in average global temperatures on earth measured over a long period. It has been attributed to the large scale deforestation by man for different purposes. We consume a lot of fuel annually. With an increase in the human population, it has become impossible to meet people’s fuel requirements. Natural resources are limited, and we must use them judiciously. If we exploit natural resources like forests and water bodies, it will create an imbalance in the ecosystem. Global warming is not limited to the rise in temperature. It has other effects too.

Role of Human Activities in Global Warming :- 

Human activities mainly responsible for global warming are as follows:-

Burning of fossil fuels

Deforestation

Farming

Landfills

Over Population

Burning of fossil fuels :- With the industrial revolution, human beings began to burn vast amount of fossil fuels like oils and gases for the generation of power and heat, these fuels and oils when burned, release carbon dioxide and other harmful gases in the atmosphere rising up the natural greenhouse effects. As a result, more heat is absorbed into the atmosphere and the temperature of the earth rises.

Deforestation :- Forests are a boon for the climate of earth. Humans clear forests and cut down or burn trees for obtaining wood, developing infrastructure, making paper from the wood pulp and many other activities. Trees absorb carbon dioxide and release oxygen as they grow. Clearing forests and cutting or burning trees releases the stored carbon dioxide back into the atmosphere. Forests are the carbon sinks and destroying forests turns these carbon sinks into a source of greenhouse gases which fuels climate change even more. Globally one-fifth of the greenhouse gas pollution comes from forest degradation. Reforestation, planting trees and preventing deforestation is important for better climate.

Farming :- Many animals that are gazed like, sheep, goats and cows produce greenhouse gas methane that contributes towards global warming. Farmers use high amount of fertilizers that release nitrous oxide a greenhouse gas with 300 times as much heat-trapping power as carbon dioxide. The use of different fertilizers and different stock feeds can help in reducing global warming.

Landfills :- The garbage and waste that we throw out of our house go to landfills. Some of this garbage is used by the recycling companies to make useful products. The garbage used for recycling process releases toxic gases in the atmosphere. Most of the garbage is burnt and emits gases like methane in the atmosphere that causes global warming.

Overpopulation :- More population means more pollution. Rise in population raises the demand of electricity, goods, food, transport, infrastructure etc. We exploit more natural resources and all this ultimately leads to global warming.

Finality :- It is a fact that burning fossil fuels like oil, coal and gas releases greenhouse gases in the atmosphere. The gases raise the temperature of the atmosphere. The switch to renewable resources for energy such as wind energy, solar energy and hydropower will help to moderate the demand of fossil fuels which will cut down the emission of greenhouse gases. We can also contribute by planting trees, saving electricity, using public transport instead of car, and creating awareness to prevent global warming.
