“Global warming is the gradual rise in the average temperature of the earth’s surface, due to the increase of certain gasses in the atmosphere” (Finn, 2008:191).This occurs when the radiation from the sun is absorbed by the earth’s surface then radiated back into the atmosphere ,when it reaches the atmosphere it warms the air. In the atmosphere there are gasses such as carbon dioxide, methane and water vapour. These gasses acts as blocking lids in the atmosphere causing the air below to remain hotter than it would have been without the gasses acting as the blocking layer. I consider global warming as a vital and severe issue in South Africa, according to Mark he stated that it is predicted that by 2025 five billion people will experience water stress (Mark, 2004:2).So people really need to find a way to curb this global warming before it is too late, if it is not taken seriously South Africa will suffer severely. The purpose of this assignment is to focus on the causes, impacts and solutions of global warming in South Africa.
1.1CAUSES OF GLOBAL WARMING”Humans are primarily responsible for global warming. These activities immensely destroy the earth .The emission of carbon dioxide from vehicles, the burning of fossil fuels, cutting down of trees and forest to build buildings and malls, the dumping of trash everywhere and not recycling it, excessive use of plastics, smoke from factories. All these activities are done by human beings are big factors of the polluted gasses in the air and the warming of the earth which destroys ecological balance of the nature leading to global warming” (dose, 2014:4)
1.2 DEFORESTATION AND INDUSTRIAL EMMISSIONSDeforestation is the act of humans, people cut down trees for an open space they could build their houses on. Trees act as carbon sinks; they absorb the carbon dioxide in the atmosphere during photosynthesis. When trees are cut down carbon dioxide in the atmosphere cannot be absorbed and its concentration will be very high. Industries in big cities produces large amount of pollution in the air and add up to toxic gasses in the atmosphere which contributes to global warming.
1.3GREENHOUSE EFFECTIs the process whereby the heat from the sun is trapped by the atmosphere, causing the earth to become warm due to the burning of fossil fuels, deforestation, resulting to the concentration of heat to increase abnormally(dose,2014;1).
1.4 DEPLETION OF OZONE LAYEROzone layer is the layer that protects the surface of the earth from ultra-violet rays causing diseases like skin cancer (dose,2014;3).When the ozone layer is depleted; it is when the harmful gasses damaged the ozone layer and formed holes allowing the ultra-violet rays to enter the surface earth making earth warmer.
1.5 BURNING OF FOSSIL FUELSFossil fuels contain too much carbon and other gasses, so burning fossil fuels produces large amount of carbon dioxide in the atmosphere and carbon dioxide is the greenhouse gas which contributes to global warming.
1.6 VOLCANIC ERUPTIONSIt is one of the major causes of global warming. The eruptions contain of dust particles which remains in the atmosphere for plenty of years and act as blocking layers that block the sunlight from reaching the earth surface making it less warm. These dust particles have an impact in the balance of the earth and becomes a contributing factor of global warming (dose, 2014:2).
2. IMPACT OF GLOBAL WARMING
If global warming continues South Africa could be in a severe danger. The major impacts of global warming are:
2.1DISEASE OUTBREAKHigher temperatures accelerates the maturation of disease-causing agents in the organism that transmit them especially mosquitoes and insects. Higher temperatures can also lengthen the season during which mosquitoes are active.
2.2 FLOODINGGlobal warming causes an increase in the intensity of rainfall. Since high temperatures speed up the process of evaporation and raise the amount of water vapour in the atmosphere, resulting to heavier rainfalls, and heavy rainfall result to flooding. When there are floods people are at risk of being buried alive, left homeless and lose their tangible properties .Also during floods as crops being washed away people are left to die of starvation as some were only depended on subsistence farming.
2.3 WATER STRESSThe decrease in available water, especially in underdeveloped areas will mean that levels of sanitation and hygiene will deteriorate. Plenty of diseases such as cholera, dysentery and tuberculosis could become more common as people will not have water to keep themselves and their environment clean.
In agriculture a hotter and drier climate will have severe implications in the agricultural industry. This will affect plenty people and for farmers their produce is their only source of income to support their families. So during these high temperatures the crop yields decreases and more technology will be needed of which the farmers cannot afford the machinery to improve their farming and will be left with no money and food as they do not have formal education. This entirely would lead to food insecurity people will die of hunger and starvation as the majority of people depends on subsistence farming, the government will need to import food from other countries and that would cause a drastic impact to the gross domestic product of the country.
Lack of water will not only affect agriculture but all other natural plants .Plenty of plant species are challenged by small amount of rainfall and the increase of temperatures and could face extinction in the near future. Plants and animals play a vital role in the tourism industry; plenty of people travel to South Africa to see immense diversity in plants and animals. The economy will be negatively affected as plant diversity is key to South Africa’s flower-based export market. All tourist related business such as hotels and lodges. And even local artists will also lose revenue. The absence of plants will also contribute to worsening the phenomenon of global warming as plants acts as carbon sinks so their absence will lead to an increase of the carbon dioxide concentration in the atmosphere(Finn 2008;193).
3. WAYS TO CURB GLOBAL WARMING3.1 AFFORESTRATEPlanting plenty of trees in open available spaces would help minimize carbon dioxide in the atmosphere as they are the lungs of the atmosphere and carbon sinks. Trees absorb carbon dioxide and release oxygen during the process called photosynthesis. This is the easiest way to curb global warming, and also in our roof tops we should plant more trees and as citizen should promote green bays as greening plays a vital role in reducing the carbon dioxide concentration in the atmosphere.
3.2 USE PUBLIC TRANSPORTCars dump an immense amount of carbon dioxide. Picture this early in the morning everyone is heading to the CBD using their private cars, the carbon dioxide released by those cars is very immense. So if people could use public transport at least there will be less carbon dioxide produced by vehicles as there will be few cars in the road and global warming will be prevented by lessening the greenhouse effect.
3.3 EDUCATIONPeople should be educated about the issue of global warming .Since plenty of people know nothing about global warming and are illiterate they at least they need to be educated about it so they should know the dangers and be able to adapt and come up with solutions and become good citizens to save Africa from this giant of global warming.
3.4 REUSE AND RECYCLE PRODUCTSThis could help an individual playing a role to stop global warming. For example, recycling paper will ensure that the large scale felling of trees to produce paper is stopped as trees are the lungs of the earth so they can reduce the amount of carbon dioxide in the atmosphere.
4. CONCLUSION In conclusion, I have accomplished the purpose of this paper which is to discuss the causes, impacts and solutions to this global warming. Therefore as citizens as we have studied or heard about the issue and how we are between the issue of life and death due to this critical condition, we have to become the fists and fight this giant called global warming before we lose so much .It is never too late for a change.
