tractors and steam ships (B.Nebel and R.Wright 1995). Stationary steam engines were rapidly established in all the major industries. The major fuel for steam engines was firewood. By the end of the 1800’s‚ the demand for energy was ever increasing and firewood around industrial centres was becoming scarce. This led to a switch to coal as the major source for fuel and energy. As well as powering steam engines coal became widely used for heating‚ cooking and industrial processes. Air pollution during

Why should we conserve our wildlife? You will be curious to know why we should save endangered species. Why is that all policy makers‚ scientists and interest citizens argue that species extinction is one of the most serious environmental problems? The importance of the need for protecting endangered species is discussed below. i) Value as genetic reservoir: Plants and animals possess undiscovered or undeveloped traits‚ which are very important for the survival of a particular species.

This will conserve the fossil fuels we are currently consuming at an alarming rate. Many little things can be done in an attempt to conserve energy in the home. It is knowing how to do these little energy conservation processes that many people do not know about‚ understand‚ or just don’t care. Another way relating to how we can

12.1 The Fossil Record 1. Form in Several Ways (The following are some of the processes that make fossils.) a. Permineralization minerals carried by water are deposited around a hard structure (may replace the hard structure) The most common fossils result from this process. A1. Natural Casts form by water removing the bone/tissue‚ leaving an impression in sediment. Minerals fill in the mold‚ recreating the original shape of the organism A2. Trace fossils record activity of an organism. Ex

We need to conserve what we have to able to enjoy it now and also for our future generations. That’s how I am about to talk what Mr. John Muir did for our country.

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

Conserving water can greatly limit the negative impact we have on the environment. By thinking conscientiously and creatively‚ we can make sure that everyone has enough water‚ while also minimizing the energy we use to bring it to our faucet or garden hose. Plus‚ using water wisely can lower many water bills. At Urban Times‚ it has been high on our agenda to bring more awareness to the increasing scarcity of water. This infographic‚ brought to us by Seametrics‚ illustrates that our water consumption is

What is Alternative Fuels Alternative Fuels come from resources other than petroleum. Alternative fuel uses sources like corn‚ vegetable oils‚ animal fats‚ natural gas‚ propane and hydrogen. Various Alternative Fuels are produced domestically‚ thus reducing our dependence on imported oils and some are derived from renewable sources. Alternative fuel produces less pollution than normal gasoline or diesel (U.S. Department of Energy‚ n.d. ). Alternative fuel is produce for a variety of vehicles
