Fossil fuels such as gasoline‚ methane and propane contain mostly carbon. When these fuels are burned‚ they react with oxygen and produce carbon dioxide. Because of our heavy use of fossil fuels‚ the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide. Most of the light energy from the sun is emitted in wavelengths shorter than 4‚000 nanometers (.000004

non-renewable energy resources. Hello there! A very good morning and I am Pranav Athreya and you have guessed it right‚ I am speaking for the topic Renewable energy is the need of the hour. At present‚ the main energy sources used are non-renewable fossil fuels like coal‚ petroleum‚ and natural gas. There are many disadvantages in using these non-renewable energy sources. Irreversible damage to the environment by pollution and global warming‚ damage to the eco systems and threat to Life itself. So my

Unless a person lives in a country where technology is prevalent‚ one’s life is most likely influenced by technology in one way or another. For example if one looks at the devices in a modern day home‚ a refrigerator‚ an electric stove‚ a blender or a toaster oven will be found. In the living room‚ one will most likely have a television and perhaps a computer. A large percentage of people own cell phones to stay connected with friends‚ family‚ colleagues and business associates. The most up to

by about 80 percent during that time. The amount of CO2 in the atmosphere today far exceeds the natural range seen over the last 650‚000 years. Most of the CO2 that people put into the atmosphere comes from burning fossil fuels. Cars‚ trucks‚ trains‚ and planes all burn fossil fuels. Many electric power plants do‚ as well. Another way humans release CO2 into the atmosphere is by cutting down forests‚ because trees contain large amounts of carbon. People add methane to the atmosphere through livestock

The 11th hour Story of the film film is preceded by the introduction of the environmental problems that plagued the world today. This introduction is intended to give an overview to the viewers about the negative impacts caused by human activities that are less responsible for the stability of the environment in general. Then proceed with the analytical discussion about things that appear in and around the environmental issue‚ and ended with optimistic statements proposed to raise the confidence

Part B: Summary In his article ‘Fossils Fuels Improve The Planet’‚ Mr Alex Epstein’s main claim was that fossil fuels are not dirty energy as they have created clean‚ healthy and liveable human environment. He also concluded that unlike fossil fuels‚ solar and wind energy - dubbed as cleaner energy - are expensive‚ unreliable and not abundant. He began by arguing that fossil-fuels-powered technologies and facilities have enabled humans to live in the most clean‚ healthy and liveable condition in

the amount of carbon in the atmosphere climbs! (Venkataramanan‚ M & Smitha 2011) One of the human activities that contribute to global warming is the burning of fossil fuels. This activity is the primary human cause of global warming as it is the main contributing source of greenhouse gas (Venkataramanan‚ M & Smitha 2011). Fossil fuels such as coal‚ oil‚ gasoline and natural gas (Feinstein‚ D 2006) are carbon-based and will produce carbon dioxide as it was once alive as plants or animals (Wilson

temperature. I believe are affecting global warming by burning fossil fuels. I think this because of the sea level‚ burning of fossil fuels‚ and deforestation. One reason I believe humans are affecting global warming is because the ocean has risen about 4-8 in the last 100 years. That may not sound like that much but it’s a significant amount. In an online article it says‚ it’s getting hotter because humans are burning fossil fuels which trap heat and energy into the atmosphere. Thus heating up

only cause of the change in these conditions. The world’s increasing the usage of fuels and petroleum day by day increases the world’s average temperature. I agree that they have a major role in our lives and I also agree that we need them to do our daily chores but this increase may end up as very tremendous and huge worry to everyone living on the planet. The gases that come out after the combustion of these fuels and also from the chimneys of the factories‚ combine and add up the concentration
