Life on this planet Earth is the product of a delicate balancing act provided by nature. Mankind’s very existence is totally dependent on this fragile ecosystem’s ability to maintain itself. A valuable player in the balance of the environment‚ the ozone layer‚ is facing a very serious threat by man. Chloroflourocarbons (CFCs)‚ are chemical agents commonly found in refrigerants‚ aerosol sprays‚ and in the manufacturing of Styrofoam and industrial solvents. With the rate of more than a half-million

Hell on Earth "A lifetime of happiness‚ no man could bear it. it would be hell on Earth." This quote means that no one can be happy all the time‚ it is not healthy.

While most of us strive for a lifetime of happiness‚ it is only in our sadness that

introduction lGlobalwarming refers to an unequivocal and continuing rise in the average temperature of Earth’s climate system. Since 1971‚ 90% of the warming has occurred in the oceans. Despite the oceans’ dominant role in energy storage‚ the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth’s surface. Since the early 20th century‚ the global air and sea surface temperature has increased about 0.8 °C (1.4 °F)‚ with about two-thirds of the

The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air‚ the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer‚ and the result is global warming. On the other hand‚ if there was no greenhouse effect‚ the earth would be too cold for humans to comfortably exist. In order

Humans are facing serious problems due to the fact that we are destroying our planet. The root of our troubles begins with the division of labor. In The Wealth of Nations‚ Adam Smith claims that the division of labor saves time by “[increasing] the quantity of work‚” but most importantly it allowed for the invention of new machines (7-9). The organization of labor along with new technology raises productivity‚ and this eventually led to the green revolution (c 20 Feb‚ 2017). The green revolution

If I told you that your casual cruising around town or your habit of just tossing your drink in the trash without dumping it out was causing major harm to our earth‚ would you be concerned? Today‚ our carbon emissions are skyrocketing so alarmingly fast‚ the atmosphere has not been this warm in 66 million years. The excess carbon has caused a five degree fahrenheit increase in our planet’s atmosphere over the

of the Moon’s origin? The currently accepted hypothesis for the Moon’s origin--which is supported by chemical analysis of Moon rocks--is that it began as part of Earth but was blown off when the early Earth was struck by a Mars-sized early planet (retroactively named Theia). Huge amounts of debris were ejected into orbit around the Earth‚ where most of it coalesced into the Moon. The other moons in the solar system have different origins. The small ones are mostly captured asteroids‚ I think‚ while

has been rising by 0.5° every year and the highest temperature recorded was 47.6° in Faya‚ Chad in 22nd June 2010. This causes the sea levels to rise due to the snow melting. It is said that the sea levels will rise by at least 25 meters by the year 2100. The sea surface temperature has risen in the last few years. This means there will be more evaporation taking place and this frees several chemicals which help global warming take place. Graph showing the number of storms per year during the years
