Every individual has responsibility to use natural resources judiciously. This will give equal opportunity to all to use the resources for the benefit of mankind. One should not be selfish to spend the available resources without thinking of other fellow beings. There is no limit to spend natural resources if available plenty but at the same time one should realize that natural resources are non-renewable sources. The future also depends on such resources. Every individual should think himself or

CE : Section 5 Fossil Fuels 1. 93 1(c) Alkenes can be obtained from petroleum fractions by a process called ’cracking’. Using a suitable petroleum fraction‚ a student carried out this process in the laboratory and collected the gaseous product over water. (i) What is ’cracking’ ? (ii) Draw a labelled diagram of a laboratory set-up that can be used for carrying out the process and collecting the gaseous product. (iii) An important safety precaution in the experiment is to prevent sucking

average temperature of the Earth caused by increasing concentrations of greenhouse gases produced by human activities‚ such as deforestation‚ use of fertilizers‚ fossil fuel combustion and cement production. According to the global warming theory‚ the intensification of industrial activities during the twentieth century (based on the fossil fuel combustion such as petrol and coal) increased the concentration of CO2 in the atmosphere. The increase of the global temperature and the new composition of the

the atmosphere becomes worse and worse. Air pollution is the pollution can make people live with huge danger and bad moods. In cities‚ the largest source air of pollution comes from burning fossil fuels. Cars‚ heavy duty trucks‚ trains‚ airplanes‚ shipping vessels all burn a large amount of fossil fuels to work. Emissions from vehicles contain many pollutants. Dangerous gases such as carbon monoxide and oxides of nitrogen which are released by vehicles may cause great harm to people. It can cause

In 2013‚ 82% of human-produced greenhouse gas emissions were carbon dioxide (Nasa climate change). This resulted from the burning of fossil fuels‚ solid waste‚ trees‚ wood‚ and other chemical reactions. The biggest reason is because of the burning of fossil fuels this includes driving your car and nuclear power plants. Another greenhouse gas‚ methane‚ comes from landfills‚ coal mines‚ oil‚ natural gas operations‚ and agriculture. It represented

submitted by : Baljinder singh. Ways to Tackle The Problem Of Global Warming. The world is suffering from many worrying threats. Global warming is one of those . Global warming is increase in temperature due to the pollutants added to the air which imbalance the nature.Here we discuss some reasons why global warming occurs and will also discuss some solutions to tackle this problem. Since the mid ninteen sixties environmentalism has exploded as a movement . Many environmentalists view modern industrial

that run on biodiesel get thirty percent better fuel economy than gasoline-powered vehicles (Perritano). The many forms of biofuels make it easier to obtain and use. Biofuels are better for the environment because they reduce greenhouse gas emissions. For example‚ ethanol reduces greenhouse gas emissions up to sixty-five percent (Perritano). Biofuels are a source of energy from plants that can help fuel our vehicles and our lives. A biofuel is any fuel that is made from plant material. Many biofuels

October 4‚ 2010 This topic of this research paper is to discuss why we need to switch to alternative energy sources. Alternative energy sources are readily available‚ environmentally friendly‚ and cost effective. Unlike fossil fuels‚ there is an unlimited amount of resources‚ and a lot less pollution. Energy demands of our population are steadily rising. In the 1960’s energy consumption had increased 51 percent‚ compared to 36 percent in the 1950’s (Hakes‚ pg 17). The

it is gone. Instead of using fossil fuels and having them burn to waste use solar energy and use what the sun gives us every day. Solar energy is an effective alternative source because there is very little pollution‚ they cut down on fossil fuels and are cost effective. Solar panels give off no pollution‚ radioactive waste or carbon dioxide‚ the only pollution is from the manufacturing‚ and installing which is no were close to the pollution of nuclear‚ fossil fuels‚ or wind energy.
