Man’s Effect on the Environment 1) SOURCES OF POLLUTION Freshwater Environments : Man pollutes freshwater all over the world in many ways there is much waste and pollution that ends up in rivers. One of the main hazards is called eutrophication‚ this process becomes enriched with artificial nutrients from fertilisers which run off into the rivers and upset the natural nutrient cycle of the river‚ lake or pond. The water turns green because of the algae which when they die multifly

Enger‚ & Ross‚ 2008) 2) Define what we mean by fossil fuels and explain why they are an attractive source of energy Fossil fuels are fuels formed by natural processes of tiny organism that have formed over millions of years. It was estimated by the Energy Information Administration that in 2007 primary sources of energy consisted of petroleum 36.0%‚ coal 27.4%‚ and natural gas 23.0%‚ amounting to an 86.4% share for fossil fuels in primary energy consumption in the world. (“U.S.

pollution‚ which mainly comes from the burning of fossil fuels as a fuel source or for electricity. Alternative energy‚ also known as renewable energy‚ is a solution to the problems caused by fossil fuel burning. Many countries around the world are beginning to switch to renewable energy. Following this example‚ switching to alternative energy in America is a realistic solution to the problems caused by obtaining energy from nonrenewable sources. Fossil Fuels are natural materials

Cause of acid rain (10) The history of acid rain caused by human activities began with the industrial Revolution in about 1750. This is when steam power began to be used to drive machinery. This was when large amounts of fossil fuels (coal‚ petroleum and natural gas) began to be burnt in order to produce energy. The problem of acid rain became gradually worse until 20th century‚ scientists began to observe widespread environmental damage. Since the problem of acid rain is discovered

which is made from fossil fuels. Fossil fuels such as oil‚ coal‚ and natural gas are nonrenewable resources. They will run out one day and that’s what the U.S. relies on for gas and electricity. Renewable energy such as solar‚ wind‚ and hydropower are infinite sources. The U.S. depends on the finite resources of fossil fuels greatly‚ yet they have the ability to use renewable energy. The oil boom dates back to Henry Ford and John D. Rockefeller and some say that fossil fuels have reached the end

Alternate Energy should be used more. Renewable energy creates three times more jobs then fossil fuels. Renewable energy is being used more in the world. People are realizing that fossil fuels are going to run out soon and that it is destroying the environment. And burning these things releases greenhouse gasses that is causing climate change. Alternate energy should be used more because burning fossil fuels is causing climate change‚ drilling oil is dangerous‚ and alternate energy is clean and renewable

Depleting Fossil Fuels Axia College of University of Phoenix As human beings‚ we need energy for just about all functions associated with the luxuries of our daily lives. We need energy to heat our homes‚ to fuel our cars‚ to watch television in addition to industrial and agricultural purposes. How often do we stop and think about where all this energy is coming from? Energy is formed and disbursed through an industrial process that is performed using a number of different sources. Although

Geothermal energy vs coal powered energy‚ what say you? Geothermal energy is a renewable source of energy generated and stored in the Earth. Coal powered energy is a source of energy produced from the natural resources of the Earth. Geothermal energy and coal powered both have many uses especially in generating electricity. In this field‚ they are similar as electrical energy is generated in a similar concept. Heat from the Earth’s crust and heat produced during the burning of coals are both used

pound of Uranium has the capacity to produce the same amount of energy of 3 million pounds of fossil fuel. That ’s how powerful nuclear energy is‚ generating so much from so little unlike our common source of energy today namely fossil fuel. That is why nuclear energy is the best alternative source of energy to fossil fuel. Even thought there are hearsays that nuclear energy isn ’t safe as the use of fossil fuels‚ there are advantages of nuclear energy that outweighs the disadvantages and actions that

Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar power‚ or wind turbines; we must find a new energy source before it
