“About 40 percent of deaths worldwide are caused by water‚ air and soil pollution‚” (Lang) what do people think of when they hear pollution? Some would think of dirty skies and blackened waters or others would think of landfills. They are all correct‚ each one of those images is a sever pollution problem. (Socha) For the last several years the problem of too much pollution has been brought to public attention and small steps to stop it have been taken but the main causes of pollution are still there

Topic: The Benefits of Trees Thesis statement: The benefits of trees can be grouped into social‚ communal‚ and environmental categories. Most trees in our communities are planted to provide beauty or shade. These are two excellent reasons for their use. Trees serve many other purposes or functions which should be considered when selecting trees for landscaping. The benefits of trees can be grouped into social‚ communal‚ and environmental categories. We like trees around us because they make

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done‚ the rainwater samples were tested using a pH meter. The results of the pH test

pollutants in the atmosphere over the last three centuries. Before 1950‚ the majority of this pollution was created from the burning of coal for energy generation‚ space heating‚ cooking‚ and transportation. Under the right conditions‚ the smoke and sulfur dioxide produced from the burning of coal can combine with fog to create industrial smog. In high concentrations‚ industrial smog can be extremely toxic to humans and other living organisms. London is world famous for its episodes of industrial smog.

Gases produced by human activities mainly due to exploitation of resources and industrialization cause air pollution. Green house gases mainly chlorofluorocarbons; carbon dioxide‚ sulfur trioxide and nitrogen dioxide contribute to air pollution. Why is air pollution such a serious issue? Air pollution is a serious issue now because many respiratory related deaths are caused by air pollution. Also air pollution disrupts the eco-system and the

for example to drive a car‚ manufacturing and generating electricity. Consequently‚ the production of an output of energy through the process of burning fossil fuels such as gasoline and diesel releases sulfur dioxide and nitrogen oxides‚ which are two main air pollutants. In addition carbon dioxide is emitted by the burning of fossil fuels for electricity generation‚ for industrial uses‚ transportation‚ homes and commercial buildings. All industries that manufacture chemicals‚ metals‚ fertilizers

author of the advertisement‚ which is an environmentalist‚ is stating that trees are irreplaceable in our environment. They filter the air by capturing airborne pollutants‚ condensing heat‚ and absorbing contaminants such as carbon dioxide‚ nitrogen dioxide‚ and sulfur dioxide. Tress help regulate the ecosystem. When there are fewer trees‚ there are fewer chances for rain. As a result‚ there will be less water for providing irrigation for harvesting food. Once that occurs‚ there is famine‚ which has been
