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...

Global warming is a very dangerous problem in our world today. Responsible, and potentially responsible, for new diseases, health problems, and land loss, this problem deserves more attention than it is currently receiving. Presently, scientists believe that human activities are responsible for...

Thousands of years ago, the earth was beautiful, skies were clear and smog-free, the ocean was rare with toxins, and man did not suffer much from pollution. However, the industrial revolution came into effect, as technology brought the world into a new era of possibilities. This new era also broug...

Global Warming: Society's Warning I feel strongly that global warming is affecting my community because it's effects reach across every town in every country across the entire planet. Global warming is sometimes referred to as the greenhouse effect. The greenhouse eff...

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...

Global Warming Human kind has entered a brand new relationship with the earth. The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think, and in the way we live-is needed now. Global warming is the most urgent environment...
