temperatures will continue to rise. 2. Carbon dioxide has always been in the earth’s atmosphere but in the past 30 years there has been a major increase of carbon dioxide throughout the planet. Fossil fuels has been identified as the main reason for the risen temperatures because the amount of fossil fuels that is being created. 3. There are many ways to prevent global warming‚ the most effective way of slowing down global warming is to save energy. This can be done if we limit pollution‚ choose

Non-renewable sources of energy normally have more negative impacts on the environment and human life than renewable energy. Fossil fuel is made from the long decay of dead animals and plants. Fossil fuel can be found in the form of coal‚ crude oil and natural gases and energy can be harnessed from these. Therefore‚ these forms of fossil fuel need to be extracted from the source first and then they can be used to generate electricity. Nuclear energy refers to the energy in the

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‚

reliance on fossil fuels‚ with 43.4% of the world’s energy consumption coming from fossil fuels (environmental literacy council‚ 2008).With the use of fossil fuels such as petroleum in cars‚ the emissions and subsequent pollution to the environment is increasing. Car exhaust is a large contributor to the emissions along with the mining or harvesting of the raw materials. Petroleum is involved in the construction of rubber‚ plastics and nylon. It involves the hydrocarbon burning of fossil fuels‚ significantly

you will no longer be able to drive your vehicle to work or anywhere you would like to go. This could be a possible outcome due to the fact that over the years‚ thousands of cars have been manufactured and most of them run and depend on fossil fuels. Today these fossil fuels are potentially in danger of running out due to the use of them in the vehicles we travel in every day. Currently cars such as hybrids are being manufactured and are being brought to attention so this problem will be less likely

Finding Alternative energy sources is a significant issue from all over the world. In contemporary society‚ due to the lack of fossil fuels and environmental problems like air pollution‚ alternative sources of energy have being utilized widely for different domestic and industrial applications. Biogas is one of the alternative energy which instead of fossil fuels. This essay will focus on how to harness biogas effectively and it will highlight biogas as an important alternative energy plays

incineration of waste within the Sun (Touran). Although it may seem that nuclear energy isn’t safe for the environment‚ it is exponentially cleaner than current fossil fuels. By 2013‚ it has on average prevented 64 gigatonnes of CO2-equivalent greenhouse gas and 1.84 million air pollution-related deaths (Hansen and Pushker). With the replacement of fossil fuels as an energy source‚ this number can only

They are millions of years old and are fossilized under rock and sand. They are efficient energy producers‚ however‚ they also produce carbon dioxide‚ a pollutant. Their energy is released through combustion where heat starts an exothermic reaction. The hydrogen and carbon molecules react chemically to produce heat. Fossil fuels like natural gas can be used

Nuclear power is one of the latest ways to make energy. Although it is non-renewable it provides 6.3% of the world’s energy and 15% of the world’s electricity. It is designed to extract energy from the nucleus of a Uranium atom. Unlike fossil fuels‚ nuclear power doesn’t give off any greenhouse gases but produces radioactive and nuclear waste. France‚ Japan‚ and the United States of America generated 56.5% of nuclear power. In 2007‚ there were 439 nuclear power reactors operating around
