Fluoride
.... of the amount of the beneficial trace
element fluoride found in water to provide for the proper protection of teeth.
Fluoridation has been widely utilized in this country since 1945. It does not
involve adding anything to the water that is not already there, since virtually
all sources of drinking water in the United States contain some fluoride.
Fluoridation is a form of nutritional supplementation that is not unlike the
addition of vitamins to milk, breads and fruit drinks; iodine to table salt; and
bo .....

Global Economy And The Environment
.... more likely to have a more harmful environmental impact from growth and
development, as opposed to the local corporations. This is because MNCUs may
not be as knowledgeable as local corporations in resource utilization and land
management. This also refers to the notion of Rthe locals know their land
better than anybody elseS. The tropical rain forest of Brazil is a good example
of this. The RindigenousS or the local people have a good understanding of how
to extract and utilize its resources in a .....

Global Warming
.... into the atmosphere. The radiation from the
sun gets trapped in the bag of carbon dioxide that surrounds our earth.
One main reason for the problem of global warming is the burning of
fossil fuels. Fossil fuels are coal, oil and natural gases. We use these fuels
to run factories, power plants, cars, trucks, buses, air conditioning and etc.
The people of the earth are putting 5.5 billion tons of carbon, in the form of
carbon dioxide in the air every year! Seventy five percent of this is fossil
fuels.

population size, atmospheric concentrations of these gases and global
temperature relative to time and with respect to each other is presented here to
demonstrate the relations among these factors.
POPULATION GROWTH
Many of us have seen linear graphs of human population showing the enormous
growth in the last two centuries. However, significant changes in population
dynamics are lost in the exponential growth and long time scales. If the data
are replotte .....

Global Warming
.... in global temperature of approximately 1°
C (approximately 1.8° F). Even a limited rise in average surface temperature
might lead to at least partial melting of the polar icecaps and hence a major
rise in sea level, along with other severe environmental disturbances. An
example of a runaway greenhouse effect is Earth's near-twin planetary neighbor
Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered
surface is hot enough to melt lead.
Water vapor is an important "greenhouse" gas. .....

Greenhousing The Wrong Way
.... With Me?
As the temperatures rise, the waters get warmer and begin the melting
process of the polar ice caps (Popular Science).
Long term predictions of Global warming say that the melting of the
polar ice caps will continue causing ocean waters to rise, resulting in massive
coastal flooding of major cities such as Los Angeles and Miami.
If the next century's warming stays at a low end of estimates, the
consequences are likely to be mild. But if warming reaches the middle or top
estimates, we are lik .....

Green Laws Boost Clean-up Iindustry
.... EU-directives are getting close, and
everything se-ems to show that the laws will be enforced.
Yet far from all companies have to meet with the
raised finger of the law to start investing in their environmental
responsibilities. Investments on a volunta-ry basis are often due to the fact
that it makes good ecnomic sense or because it gives the corporate image a face-
lifting.
Seen from a geoprahical point of view Germany and primarily eastern
Europe form tremendously good breeding ground for the sa .....

Greenpeace

a action for Greenpeace sometimes means that you have to break the law or at
least bend it a little. In USA where they protested against some factories
which deliberately lead their toxic waste to lakes nearby, Greenpeace sealed the
pipes, from which the toxic waste was coming from and furtermore the activists
refused to leave. A up-to-date example could be Mururoa, where the French
government held a series of underground nuclear tests and banned all nearby

wiped out by laws which allowed the birds to be hunted during their winter
breeding seasons when the birds were most vulnerable. By 1957, when the Nene
was named the State Bird, rescue efforts were underway. Conservationists began
breeding the birds in captivity in hopes of preserving a remnant of the
declining population and, someday, successfully re-establishing them in their
native habitat. Other programs for returning captive birds to the wild li .....

Hemp: The Truth About The Earth's Greatest Plant

and flowers produce the drugs marijuana and hashish. However, sterile breeds of
the plant are still illegal to grow in the U.S. Literally millions of wild hemp
plants grow throughout the entire Midwest today. Wild hemp, like hemp used for
industry purposes, is useless as an intoxicant. Yet U.S. drug law states that
one acre of this can result in the owner being sentenced to death. The death
penalty exists for growing one acre of perfectly harmless, non-intoxicating

Hemp
.... It's ironic that we have the opportunity to solve most
of Canada's critical environmental issues in one fell swoop . . . with one
simple plant. It is ignorance and the maintenance of the status quo that has
blinded and crippled our ability to realize this resource.
INTRODUCTION
A plant exists that is so strong that it can be grown without requiring
chemicals in almost every part of the world. Many have touted this plant as a
possible way in which to wean society from its dependence on fossil fuels .....

The Hippopotamus: Endangered Species Report

exponential rise to hippo ivory trade.
"European and African activists are petitioning advocacy groups, including last
week's annual Convention on International Trade in Endangered Species in Florida,
for a ban on hippo poaching. But they say they're a long way from putting an
end to the slaughter." (Howard & Koehl)
The hippopotamus is an enormous amphibious animal with smooth, hairless skin.
Hippos can be found in Liberia, the Ivory Coast, and a few can al .....

Climatic Change And Its Effect On Society

concerns being addressed by researchers in this region. climate modellers have
predicted a large increase in temperature for this region, which could lead to
even drier conditions and enormous stresses on vegetation in the western
Canadian boreal forest. This type of impact was observed following the 1988
drought it experiences, when there was a die-back of aspen over extensive areas
of the aspen parkland in Western Canada. Associated with thi .....

Hurricanes
.... air soaring upwards in the thunderheads. The air begins swirling around the
storm center, for the same reason that the air swirls around a tornado center.
As this air swirls in over the sea surface, it soaks up more and more water
vapour. At the storm center, this new supply of water vapor gets pulled into the
thunderhead updrafts, releasing still more energy as the water vapor condenses.
This makes the updrafts rise faster, pulling in even larger amounts of air and
water vapor from the stor .....
