happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Most greenhouse gases are released by the burning of fossil fuels for heating‚ cooking‚ electrical appliances‚ transportation‚ and manufacturing‚ but they are also released as a result of the natural decomposition of organic materials‚ wildfires‚ deforestation‚ and land-clearing activities. The diffusion of these

Air Quality Essay – paragraph 2 and 3(body) By Edwin Lin‚ The air quality is deteriorated by humans heavily using fossil fuels to power up automobiles‚ generate electricity‚ and used for many other purposes. Unfortunately‚ fossil fuels are nonrenewable resources‚ and the burning of the fossil fuels releases the pollutants into the air‚ and forms a mixture of fumes with the air. It is called smog. Smog can block the radiant beams of energy from the Sun from entering and exiting the Earth’s atmosphere

fossil fuels‚ which is a limited energy source and also poses negative effect on environment due to CO2 removal. Concerns about increased global energy demand‚ finite natural resources and environmental issues‚ are thus intensifying the search for sustainable‚ clean‚ renewable and eco-friendly alternatives to fossil fuels (Venkata mohan et al.‚ 2008). Renewable energy can be defined as energy that comes from constantly replenished resources such as sunlight‚ rain‚ wind‚ hydropower and fuel cells.

urgent. Therefore‚ research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption. To avoid this disaster it is vital for us to utilize alternative sources of energy to its full potential. Widely used fossil fuels like coal‚ oil‚ and petroleum are very harmful to the environment. The earth is warming up‚ the climate

How can the alternative source of energy be harnessed effectively? Losing polluting natural resource is one of the most serious problems that people concerned during the 21st century. Scientists have found that traditional sources like fossil fuels are threatening people’s lives as well as the environment. Due to this‚ some countries have started their plans to harness‚ renewable energy and achieved satisfactory success. For a decade‚ the majority of countries in Europe have proved that used alternative

ENVIRONMENTAL PROBLEMS BIODIVERSITY LOSS Biodiversity - refers to the number and size of populations in a community; variability of species in an area In general‚ there are three categorical levels of biodiversity: 1. Genetic biodiversity - involves populations‚ individuals‚ chromosomes‚ genes and nucleotides 2. Taxonomic biodiversity - include kingdoms‚ phyla‚ orders‚ families‚ genera‚ species‚ subspecies and populations - for practical reasons‚

Increasing Oil Production in the United States of America Crude oil is a major source of energy for the world. Everyday the United States consumes more crude oil than it produces. The growing number of barrels of oil imported into the Unites States and rising gas prices are major concerns. Even though increasing the United States crude oil production may not lower gas prices immediately‚ it will eventually allow the United States to be energy independent. Oil is used in many different ways

A century later‚ oil and gas were added to satiate the thirst of industry. Man still relies mainly on these fossil fuels. Nevertheless many other sources of energy: hydro‚ solar‚ nuclear‚ wind‚ geothermal‚ biogas and wave have been taped. These sources of energy are not only renewable but clean as well.
