Heavy Metals In Africa

This produces harmful carbon emissions, and also uses a nonrenewable fuel source to make electricity. A car’s emission is the most direct contribution to pollution. Engines that burn gasoline emit harmful gases. These gases include carbon dioxide, which builds up in the air and adds to global warming. Also, cars may leak fluids which can enter water systems.

This documentary focuses on the main contributors of global climate change in three parts. In part one, the documentary deals with coal and electricity. It shows how mountain-top removal is ruining the mountains in West Virginia and how it affects the health of residents in the area. In this section, the documentary also addresses the issues of coal mining in China, including large emissions of greenhouse gases and smog. In part two, the documentary concentrates on oil and cars.

Land pollution causes the land’s productivity and potential to decline to such a level that the purpose of utilising lands for building infrastructures, housings, services, agriculture, forestry and many more for the development of human being are no longer achievable (Prabhakar, 2012). Land pollution are resulted by some sources which are deforestation, mining and construction activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters.

Introduction Pollution has been around since Ancient Rome and is described as the contamination of our natural environment that is caused by chemicals and gas (Stromberg). Because of pollution in the air, more damaging consequences such as the formation of acid rain are triggered. The largest contributors to pollution are humans through industrial factories that expel foreign chemicals into the atmosphere and cause the formation of acid rain. This topic was chosen to explore the effect of man-made acid rain as a result of pollution in the air on plants, human health, and much more. The effect of pH on oxygen (O2) consumption and carbon dioxide (CO2) production is worthy of investigation because human-caused acid rain is at large at many countries and may give clarity to other events that acid rain triggers.

Acid Rain is a form of precipitation that has high levels of hydrogen ions, and minimum ph. Acid rain can be harmful to plants and animals. The terrible chemicals in acid rain is sulfur dioxide and nitrogen oxide, which happens when molecules of water in the atmosphere to make acids. The chemicals in acid rain can peel paint from cars and cause corrosion. acid rain is incredibly power and terrible for our eco system.

Air and water pollution are significant problems that Argentina is currently facing. The air pollution is caused by vehicles and industrial factories with subsidized smokestacks. Air pollution also has long term effects on the health of those living in Argentina such as lung cancer, cardiovascular disease and chronic respiratory illness, all of which will lead to a decrease in life expectancy. The problem of the water pollution is particularly highlighted by the Riachuelo river which is incredibly polluted by chemical runoffs from surrounding factories. This water pollution in Argentina also has an effect on the access to clean water that the population has.

Well chemicals in both of these reactions can be extremely harmful and dangerous. Firstly, nitrous oxide is actually a greenhouse gas meaning it contributes to the cause of global warming and the depletion of the ozone layer. When the chemical is used in cars, sometimes the chemical can escape the engine or the tank causing it to go into our atmosphere. Nitrous oxide is over 300 times more potent as a greenhouse gas than CO2. and accounts for 5% of all U.S. greenhouse gas emissions from human activities and 6.3% in the UK; The Conversation, (2015) and Www3.epa.gov, (2015).

China is facing one of the huge problems such an environmental pollution today and it is causing irreparable harm to the country. Air pollution is the one of the form of environmental pollution that has been struggling against by China for many years. Air pollution is caused by gases released by vehicles, factories, and even smokes from burning leaves and cigarettes. Particularly, coal is the main reason for the degradation of air quality. As Tan (2013) claims “China burned about half of the world’s coal in 2009 and China receives 70 % energy from coal”.

Since that year reports have been that the Nairobi dumpsite could not handle more waste from the city, however an alternative was never provided. This then meant that the increasing volumes of generated waste have been inadequately handled from that period. Njoroge et al. (2014) states that despite the problem of improper waste collection and disposal facilities in Kenya, the composition of different types of solid waste in the City of Nairobi has been growing in the past couple of decades. They state that domestic kind of waste comprised of mainly plastics, paper and other types of solid waste have been on the increase while other kinds of waste such as organic types was decreasing.

Global warming is a serious problem that refers to having too much carbon dioxide in the atmosphere. This problem interacts as a blanket, trapping the heat and warming inside our planet. Humans are used to burn fossil fuels such as oil, natural gas and coal for energy or log and burn the forests for creating new other products. The atmosphere by that is overloaded with carbon dioxide emissions (Climate Hot Map, 2011). There are some specific waste and agricultural management practices that increase the burden on earth by releasing other global warming gases.
