Greenhouse Gases Nitrous Oxide
1,153 wordsIndeed, in my opinion, technology does owe ecology an apology. This is because ecological imbalances were as a result of the Industrial revolution, which could be said to be the beginning of the non-ending technological advancement cycle. During Industrial revolution, we began altering or climate and environment through changing agricultural and industrial practices. Before the industrial revolution, human activity released very few gases into the atmosphere, but now through population growth fo...

Heavy Metals British Isles
1,130 wordsZinc hyper accumulation in Thlaspi caerulescens as a chemical defence against herbivore ABSTRACT Thlaspi caerulescens is one of several plant species known to accumulate heavy metals in excess of 2 % of their above ground plant biomass. The reasons for hyper accumulation are unknown, but several studies conclude that it may be a plant chemical defence. This has been of interest to biologists because these metals are usually toxic. The accumulation of these metals may serve as a model for coevolu...

Methyl Bromide Uv Radiation
627 wordsOzone is a form of oxygen that is a human-made pollutant in the troposphere but a naturally produced, essential component in the stratosphere, which encircles our planet some 6 to 28 miles above the surface. The stratosphere contains a layer of ozone that shields the surface from much of the ultraviolet radiation coming from the sun. If ozone was to disappear from the stratosphere Earth would be uninhabitable for most organisms. The primary cause for this substantial ozone loss is a group of com...

1,327 wordsHuman beings are able to adapt to almost any environment, unfortunately sometimes we take advantage of our natural surroundings. We find ourselves amidst a struggle between our lifestyles and nature. Although we affect nature profoundly with our activities, we in turn are shaped by nature's potent forces. Nature can be brutal to humans, but we must remember that it merely is following its course. As a result, we must learn to coexist with it. Fire is a naturally occurring phenomenon which humans...

Carbon Dioxide Methane Renewable Energy Sources
1,623 wordsBy the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we our now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath. Many people in the world do not think that this is a major concern and that it is normal for the Earth's temperature to incr...

Environmental Protection Agency Ozone Depletion
1,137 wordsThe ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases. 1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on...

Whether these activities were essential or superfluous, the effects on and surrounding Earth are multitudinous. For example, a warmer Earth could lead to the spread of diseases, melting polar ice caps, receding glaciers, and a change in precipitation patterns (Gay 21)...

Fossil Fuels Global Warming
1,982 wordsThe Potential Markets Hydrogen ANALYSIS The Potential Markets For Non-Fossil Fuel Hydrogen? Hydrogen, most of it produced from fossil fuels, is already widely used in the chemicals industry, notably in the manufacture of fertilizers and petrochemicals. It would therefore be possible to substitute NFFH in this market. However, the total that could be absorbed by 2040 is unlikely to represent more than about 3 % of current total world energy demand. ? NFFH could be used to satisfy much of the dema...
