Cause and Effects of Water Pollution Water is a key resource on our planet and is undervalued by humans causing water pollution. Water makes up 70% of the earth and 60% of the human body‚ therefore the pollution of water is in need to come to an end because it is essential to all living aspects on earth ("Causes and Effects of Water Pollution…"). Water pollution is typically caused by littering‚ industrial waste‚ oil pollution‚ and primarily‚ by the human carelessness. It needs to be taken more

INTRODUCTION Pollution is the introduction of a contaminant into a natural environment‚ usually by humans. While most people think of pollution as chemical waste dumped into rivers‚ or factories spewing toxins into the air‚ it can also include light pollution or sound pollution. These are example of pollutions such as air pollution‚ water pollution and land pollution. Firstly‚ the air pollution is the accumulation in the atmosphere of substances that‚ in sufficient concentrations‚ endanger

Sources of air pollution Air pollution caused by vehicles has been identified as the largest contributor to air pollution in the world. Air pollution caused by vehicles is when the burning of fossil fuels to power our vehicles gives off CO2 emission. This pollution by vehicles also produces toxic substances such as sulfur dioxide and carbon which can be fatal to humans. Air pollution also comes from industry as this source of pollution spews particulate matter and chemicals into the atmosphere

Industrial Pollution Industrialization has been the hallmark of human progress. However‚ industries have become to the biggest issue of environmental pollution. Industrial pollution is pollution that can be directly linked with industry‚ in contrast to other pollution sources. This form of pollution is one of the leading causes of pollution worldwide. Industries release a host of toxic gases into the atmosphere‚ and gallons of liquid waste into the seas and rivers. Some of the effluents percolate

SOIL POLLUTION INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth’s rocky surface. The organic portion‚ which is derived from the decayed remains of plants and animals‚ is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments‚ was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient
