1,Identify and explain any three causes of global warming and its implications in Africa 2,List and explain any four effects of global warming on human health in Africa
3,How can global warming be checked or controlled?
1. Global warming is a feature of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased absorptions of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming. The following are some of the main causes of global warming; firstly, global warming is caused by burning fossil fuels. When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.
Secondly, global warming is caused by deforestation and tree-Clearing where by plants and trees play an important role in controlling the climate because they captivate carbon dioxide from the air and release oxygen back into it. Last but not the least global warming is caused by agriculture and farming where, livestock like sheep and cattle, produce methane, a greenhouse gas and when livestock grazed at a large scale, the amount of methane produced is a big contributor to global warming.
2. Global warming has the following effects on human health in Africa; firstly, in leads to infectious diseases. This predicts that global warming worsens human health conditions, especially in tropical regions. For example, an increase in temperature signifies an increase in mosquito populations, thus accelerating the risk of malaria, and other insect-borne infections. Secondly, global warming impacts into heat waves where by prolonged periods of unusually high temperatures can have serious health effects on vulnerable populations, such as the elderly and the sick.
Another effect of global warming on human health in Africa is that it leads to asthma and other respiratory diseases. This is commonly to people suffering from heart problems who are more at risk to increased temperatures, especially those living in already warm areas, as their circulatory system must work harder to keep their body cool. Lastly, global warming leads to loss of agricultural productivity. Global warming can result in droughts that can worsen living conditions, particularly in Africa there by causing malnutrition among Africans.
3. Global warming can be controlled through the following ways; Reducing the amount of electricity generated from coal and gas, Increasing the amount of electricity from clean, renewable energy sources like solar and wind, Prevent deforestation and tree-clearing, Plant more trees through reforestation and afforestation and Use different stock feeds can help to reduce farming's contribution to climate change.
