The Environmental Impact Of Eating Beef And Dairy Products
.... absorb the water, and recycle the nutrients,
the land has become increasingly vulnerable to wind and water erosion. More
than 60 percent of the world's rangeland has been damaged by overgrazing during
the past half century.
Cattle ranching has also been linked to Global Warming.
The grain-fed-cattle complex is now a significant factor in the emission of
three of the gases that cause the greenhouse effect- methane, carbon dioxide,
and nitrous oxides- and is likely to play an even larger role in Global Warming
in the coming decades. The burning of fossil fuels accounted for nearly two-
thirds of the 815 billion tons of car .....

The EPA: Can It, Will It Save Our Environment?
.... Charges of mismanagement and undue political
influence caused the head of the EPA to resign in '83. "The deputy director
resigns because of charges of making a 'hit list' of employees to be hired,
fired, or promoted because of political leanings. The former head of the toxic
waste cleanup is found guilty of perjury and obstructing congressional inquiry.
A regulation requiring treatment of hazardous wastes before disposal underground
was made in 1984." The spill of the Exxon Valdez caused the Environmental
Protection Agency to be ctiticized for slow response in '89. Texas Eastern Gas
Pipeline was fined $15 million for the cont .....

The Evils Of Hunting
.... In 1995, the number had been reduced to around 64 million. Within 20
years, in short, the duck population was reduced by almost one third, showing
the drastic toll hunting is taking on our wildlife. If we assume that other
species have been reduced in number at approximately the same rate in recent
years, then what are the larger implications for our ecological balance? If this
trend continues, by the year 2055, the members of species which are hunted could
be reduced by as much as 81 percent. (Satchell 31)
Not only does hunting reduce the number of animals, it can also be
unnecessarily cruel to the creatures. When deer are b .....

The Greenhouse Effect
.... These increases are likely to affect worldwide temperatures
dramatically. In 100 years time the average temperature for most parts of the
world will increase from between 2C to 6C if greenhouse pollution continues at
its present rate. This temperature increase would drastically affect the growth
of many different crops and cause the polar ice caps to melt, thus increasing
sea levels to rise up to several metres. If this rise in sea level was to occur
many areas would be much more prone to flooding, and generally much deeper
floods than would be expected nowdays. This flooding would happen paricularly
around coastal .....

The Greenhouse Effect
.... the rays stay in and heat the air. The greenhouse is
also called a "HOT HOUSE" because it gets so hot.
The greenhouse effect is caused by gases such as carbon monoxide, carbon
dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in
the ozone layer and do not let the suns rays escape very easily. This causes
the earth to warm up. This warming can cause droughts, and this would really
affect the farmers. This heating up will cause the plants and animals would die.

The Potential Effects Of A Depleted Ozone Layer
.... out the sun's invisible and dangerous ultraviolet rays "
( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the
environment. Ozone depletion has been described as " potential
catastrophe " and " a planetary time - bomb " ( Way, 1988, p.9 ). The four main
areas affected by a depleted ozone layer and thus by the corresponding increase
in harmful ultraviolet radiation are agriculture, wildlife, the environment, and
human health. A depleted ozone layer has a profoundly negative and potentially
devastating effect on humanity and its surroundings.
From an agricultural perspective, a diminished ozone layer p .....

The Choosing Of A Landfill Site
.... in order to gain benefit from municipal waste
decomposition processes. The landfilling of hazardous wastes is a contentious
issue and one on which there is not international consensus.
Further complications arise from the difficulty of classifying wastes accurately,
particularly the distinction between 'hazardous'/'non-hazardous' and of ensuring
that 'inert' wastes are genuinely inert. In practice, many wastes described as
'inert' undergo degradation reactions similar to those of municipal solid waste
(MSW), albeit at lower rates, with consequent environmental risks from gas and
leachate.
Alternatively, landfills can be categori .....

Value Of Environmental Agencies
.... mentions, “Indigenous people in many countries have died because of
contact with outsiders-usually whites of northern European extraction-who have
brought contagious diseases, ranging from measles to influenza, and sexually
transmitted disease”(20). With the importance of the land resources comes the
ever significance of the atmosphere. The atmosphere's most predictive component
is the ozone layer. The distribution of the forests and multiplying of grazing
cattle are causes immense damage to the ozone. John Nichol, head of Worldfest
90' production and marketing, alludes, “In Brazil and other countries in South
and Central .....

Environment Report: Tidal Power In The Bay Of Fundy
.... from 22 to 28 feet and low - water heights
vary from 0 to 7 feet above chart data. Because of these semi - diurnal tides
and the action of the St John River, slack water in the Habour occurs at
approximately tides and not at high or low water as would be the case at other
parts.
THE RHYTHMIC RISE AND FALL
In the Bay of Fundy, the tides are spectacularly large. While the rise
and fall of sea level due to tides is the most apparent aspect, it is also the
tidal currents that direct magnification of tides, and the sea level rises or
declines are due to resulting convergences and divergencies. These tides rise
and fall over a range .....

Time To Change
.... of. If we do not start taking them seriously soon it will be too late,
if it is not already. We need to reevaluate our priorities and plan for the
future existence of this world.
A group labeled the Earth-Firsters' often attempt to accomplish this task
through drastic and sometimes dangerous methods. As Joni Seager states ( The
Eco-Fringe: Deep Ecology, Pg. 636), "In Australia, Earth-First protesters
buried themselves up to their necks in the sand in the middle of logging roads
to stop lumbering operations; in the American Southwest, Earth Firsters
handcuffed themselves to trees and bulldozers to prevent logging; and in

Urban Heat Islands
.... higher than those of the unpaved faster cooling areas.
On clear, still nights when the heat island is pronounced, a small thermal low-
pressure area forms over the city. Sometimes a light breeze, called a country
breeze which blows from the countryside into the city. If there are major
industrial areas along the city's outskirts, pollutants are carried into the
heart of town, where they tend to concentrate.
At night, the extra warmth of the city occasionally produces a shallow unstable
layer near the surface. Pollutants emitted from low-level sources, such as home
heating units, tend to concentrate in this shallow layer, of .....

Using Bicycles As An Alternative To Automobiles
.... that could be drastically reduced by the increased use of bicycles.
Traffic would be a lot lighter due to the extremely small size of bicycles. It
would also greatly reduce the wear and tear on our roads and highways, and
therefore reduce government expenditure. But one of the most serious problems
it would reduce is that of pollution and smog in out larger cities.
There are more benefits to biking, though. There are benefits that come at a
more personal level.
Biking greatly improves ones health. It can be a way to exercise without taking
much times out of ones schedule. The time one would spend biking to work serves
two i .....
