We get energy from sunlight, wind, nuclear plants, and damns... However, most of the points that we use come from fossil fuels. There are three primary fossil fuels: coal, oil, and natural gas. These are composed of carbon, hydrogen, nitrogen, oxygen, and sulfur. Carbon is the major element in fossi...

There are many ways to produce electricity but unfortunately not all of them are clean and safe. Luckily here in Canada we have clean and safe alternatives to things like the burning of fossil fuels. We are the largest producer of hydropower in the world. Hydro energy is electricity made using water...

Energy is one of the most fundamental qualities in our lives. Almost everything in the world is run by energy. We need electricity to turn on the lights, gas to power our cars, and energy to give us heat to warm our homes. Today, we are totally dependent on an abundant and inexhaustible supply of...

Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms it...

Resources are the things that we can extract from the earth. Industries, which extract the earth's resources, include mining, forestry and oil extraction. Present-day civilisation is based upon a massive utilisation of non-replaceable minerals and fuels such as coal, oil and natural gasses. Oth...

Did the climate of the earth become appreciably warmer in the 20th century? What evidence suggest that this can be linked to human activity? There is widespread fact that the earths temperature has increased 0.3 – 0.6 C in the past 100 years. Some changes in the physical features of the ear...

Thermal Pollution: A Global Problem Recently, as a result of the increased energy demand, we've allowed our planet to begin overheating. With the introduction of more and more heated water into our lakes and rivers, and Carbon Dioxide into the atmosphere we've managed to raise the temperature of ...

When people think of hydrogen, outside the studying of a chemistry class or something to that effect, thinks immediately of the hydrogen bomb. This situation is obvious a big image problem. Thanks to new technology, hydrogen has escaped the imagine of the unbearable to other more economical thoug...

Environmental Changes Weather changes all the time. The average patter of weather, called climate, usually stays pretty much the same for centuries if it is left to itself. However, the earth is not alone. People are taking actions that can change the earth and its climate in important ways. ...

Air Pollution in Ontario Air pollution is a major topic in our society it is a subject to be taken seriously because it causes many problems in our environment causing it to be very unhealthy for our living lifestyle. Air pollution is described as the accumulation of something where it is no...

What is the greenhouse effect? There is speculation on whether there is such an event as the greenhouse effect. Some scientists say that there is, while some scientists say that it is just the cycle of the Earth as far as the weather. The greenhouse effect is what we call the result of harmful level...

Global warming is caused primarily by human activity such as burning fossil fuels, chemicals, and other pollutants that are later released into the earth's atmosphere. These gases affect the chemical composition of the atmosphere causing increased warming (EPA, 1999). This warming trend disturbs th...

Global warming, the increase in our earth's surface temperature, is often confused with the greenhouse effect. The greenhouse effect is what makes our planet suitable for life as we know it. It is a natural process that causes gases in the atmosphere to trap energy from the sun. This causes a r...

Global Warming Global warming is an issue that has been widely discussed during the last decade. It is probably the most threatening problem towards mother earth, and something has to be done instantly to stop or at least slow down the scary development. The gradual warming of the earth's atmosph...

Global Warming The consequences of global warming have by now come to the attention of the majority of the population of the United States of America. The gradual warming of the earth's atmosphere is due to an increased amount of carbon dioxide released into it. The burning of fossil f...

A modern city in the western world depends largely upon the generation and consumption of energy. We use wood and fossil fuels to supply our vast cities with energy but do not consider the environmental implications that are involved. We are depleting the earth of these fuels faster than they will ...

In the world there are very many different environmental issues that effect the Earth. Our mere existence causes problems and poses great threats to our environment each day. Many people think they can go on blindly living their lives; that there is nothing they can do or that they have no ef...

Global Warming is something that has been going on now for a long time. Over the years scientists have been telling people, that all the pollutants that we put in the air were doing damage to the earth and the ozone. Some scientists disagreed with that statement and because of that there was nothing...

The Greenhouse Effect The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earth's surface absorbing and trapping heat radiation which normally escapes from the earth. They inc...

Heat from our sun passes through the atmosphere, causing it to warm up. Most of it warms the earth's surface. While the earth is warming up, it sends out this heat in the form of radiation. The atmosphere traps part of the heat, and the rest escapes into space. This effect that takes place on earth...

Since the beginning of evolution, humans have been creating innovative ways to simplify life. From the discovery of fire to modern advances in technology, the main objective was to simplify adversity in life. Although modern advances in technology have proven advantageous, few people take the time t...

As far back as human history goes, scientists today have discovered the depletion of the ozone layer and have studied how it is caused by human actions and inventions that affect our environment and style of living. As the cause of this, many changes have been taking place during the past twenty yea...

For many years now, scientists have researched and test the affects of air pollution. It has already been proven that pollution and the chemical substances affect a person's health and well being. There are a lot of things pollute the air, including ourselves and what we do. Pollution is basi...
