are hydrocarbons, basically fuel, coal and natural gas. Burning of fossil fuels contributes to large emissions of carbon dioxide which is major greenhouse gas that causes global warming.
5. Agricultural activities.
The use of inorganic fertilizers and pesticides in agriculture leads to emission of greenhouse gases that eventually cause global warming.
Effects of global warming.
1. Rise in sea level.
Most of water bodies on the earth surface are made up of ice. When temperature increases, this ice melts leading to the rise in sea level.
2. Drought or famine.
Extreme rise in temperature leads to drying up of plants; drought. This causes poor agricultural productivity.
3. Emergence of diseases.
Certain diseases such as anthrax, tick - borne diseases, cholera and cancers are emerging and increasing due to global warming. Cholera for example is expected to increase with temperature since the bacterial disease which causes diarrhoea and loss of water in the body is most active in warm weather and water.
Ways of mitigating global warming.
1. Afforestation and reforestation.
Afforestation is the planting of trees for the first time while reforestation is the planting of trees as a compensation of others which were cut down. Both activities involve planting of trees which absorb carbon dioxide hence reducing its accumulation in the atmosphere.
2. Use of organic farming.
Agricultural activities should be conducted with organic manure instead of inorganic fertilizers and sprays. This increases agricultural productivity and also reduces the release of greenhouse gases.
3. Making laws and policies.
The government should put in place policies that govern global warming. This policies should emphasize on the need to reduce production and release of greenhouse gases. For example, industries that release untreated gases should be closed down or fined heavily.
4. Educating the public on global warming.
People should be educated on global warming, the causes, effects and ways of reducing it.
5. Treatment of industrial gases before release.
Industrial gases should undergo treatment before they are released into the atmosphere.
In conclusion, global warming is a worldwide issue that needs to be taken seriously since its effects are devastating yet it can be controlled with a few lifestyle changes.
