Global warming occurs when the temperature of the earth rises and this happens when greenhouse gases such as; carbon dioxide, water vapour, nitrous oxide and methane is trapped by heat and light from the sun in the earth’s atmosphere, which enhances the temperature.
What are the causes of the issue/challenge?
The causes of global warming are electrical pollution and which fossil fuels are burned to create electricity. Many pollutants are sent into the air when fossil fuels are burned and these chemicals are called greenhouse gasses. Cutting trees and throwing garbage to landfills also makes global warming worse. Consuming factory mixes in the air creates a chemical reaction and this is caused by the sun’s heat and light to add the reaction.
Who is involved in it? (Individuals/groups)
The government is involved in global warming and they are doing their best to stop this. They have enforced the Clean Air Act 1961 so there is less air pollution. This law is also making companies change their products to decrease the problems arising and it states that you may not put a certain amount of pollutants in the air. Not only does global warming affect our environment, but also our people, the society and the animals that exist in the world.
What impact does it have on the people involved/or other members of the community.
Global warming can impact the people from getting affected by bad illnesses that could make them disabled and this can also cause a death. In today’s society individuals are aware about leaving things turned on such as the television, computer and the light. Instead they spend more time outdoors and this can help prevent global warming. Individuals are now riding their bikes or walking to school instead of using public transport to lower the amount of greenhouse gases in the air. By doing this, we are also saving money at the same time.
What are the economic costs?
The economic costs of global warming will increase the cost of living such as food prices. Global warming can affect over the agricultural production where some can lead to desertification. The rise in sea levels is followed by severe loss of land as well as its structural damage and it is such an expensive process in terms of flood. Due to global warming, people migrate to one place from other and this result in overpopulation in one country and depopulation.
What are the social costs?
The social costs of global warming is an allocation of resources in a competitive market which is produced through carbon dioxide and other greenhouse gases that impose high external costs to society. These social costs are due to the over-production of energy from oil and coal that produce high levels of carbon dioxide into the atmosphere.
What are the results?
With too many greenhouse gases in the air, the earth’s atmosphere would have too much heat and as a result people, animals, plants and many more would die because the heat would be too strong.
What are the solutions?
Many people and the government are already working hard to cut greenhouse gases such as the carbon tax. There are many solutions by improving global warming such as the energy efficiency so the vehicle economy has less energy to be produced, and increases in wind and solar power, hydrogen produced from renewable sources, biofuels, natural gas and nuclear power.
In conclusion, it is recommended that everyone should contribute to global warming and anyone can make a difference. They can prevent by taking less hot showers, being aware with recycling and reducing electricity at home. Individuals should be informed about environmental issues and share their knowledge with others.
