Scientific contemporary issues: The causes and effects of air pollutants There are many different air pollutants created from many different sources. Sources of air pollution range from car exhaust emissions (Carbon dioxide‚ Carbon monoxide‚ Nitrogen Dioxide‚ Lead & particulate matter)‚ industrial sources such as factories‚ power plants and refineries (Sulphur dioxide‚ Nitrogen dioxide‚ Carbon monoxide‚ carbon dioxide etc) air-conditioning and refrigeration (CFCs). Natural sources also

In the past 30 years solar and wind power systems have experienced rapid sales growth‚ declining capital costs and costs of electricity generated‚ and have continued to improve their performance characteristics. In fact‚ fossil fuel and renewable energy prices‚ and social and environmental costs are heading in opposite directions and the economic and policy mechanisms needed to support the widespread dissemination and sustainable markets for renewable energy systems are

Before we begin to pose possible solutions to advert this catastrophe‚ we must fully comprehend the problem and all it entails.

Finally‚ this essay will discuss how deforestation in expanding industrial land changes climate. The combustion of fossil fuels is inevitable in industrial production‚ because it provides extreme high temperature and continuous heat. It is the direct contributor to climate changes by emitting large amounts of greenhouse gases‚ such as carbon dioxide‚ methane‚ sulfur

resources What are Alternative energy resources?? It is any energy source that is an alternative to fossil fuel. It is a form of energy derived from a natural source‚ such as the sun‚ wind‚ tides‚ or waves and are also known as “Renewable Energy” that do not use up natural resources or harm the environment. They are considered alternatives because they can be future replacements for the fossil fuels that now meet a considerable portion of our energy needs. What Energy Resources are we using

problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal‚ or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well. Another major man-made

tablet etc. We never really care about where the energy came from and are we wasting it? Main energy source is fossil fuels including coal‚ oil and natural gas. Many of us are uninformed about this main source of energy and how much we can take from the world. We barely know how much the world spent fossil fuels yearly to fulfill our electricity needs. The main problem here is fossil fuels are un-renewable. It takes millions of years for them to be formed and ready to use. Based on a high energies

Haleh Keshtkar November 28‚ 2011 Green Power 2 In recent years there has been more and more emphasis on finding ways to help save our resources. America has become so dependent on using resources such as oil‚ natural gas and fossil fuels‚ the most convenient form of energy‚ for our everyday lifestyle. From using cars and electricity in our homes to getting our products at our nearest retailer‚ we use a large amount of energy. With the rise of energy consumption‚ due to our lifestyles

myself mostly fear due to what basically Hardin is telling us is the past affects the future. In my opinion‚ and I believe Hardin would agree with me we are quickly over-populating the earth “our commons” therefore‚ making our common resources such as fossil fuels‚ land and water limited‚ eventually getting to the point were there is none or a very short supply of these common resources. This instills fear because we need those resources in order to survive and keep “our commons” running in the way in
