The Choosing Of A Landfill Site
.... variants, such as
mono-disposal - where only a single waste type (which may or may not be
hazardous) is deposited - and joint-disposal - where municipal and hazardous
wastes may be co-deposited 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 'haza .....

Value Of Environmental Agencies

lumber companies invading these towns and villages, their western germs are
exposing isolated, once-contained people. Kathlyn Gay, author of Rainforests of
the World, 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

Environment Report: Tidal Power In The Bay Of Fundy
.... the Bay.
This section also experiences two high and two low tides each day (semi
- diurnal), with a tidal range varying from 15 to 18 feet, depending on the type
of tides. High - water heights vary 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.

are just a few of the human disruptions to nature available to our knowledge.
We are conscious of many more, and there are probably others that we are not
aware 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. .....

Urban Heat Islands
.... tall building walls that do not allow
infrared radiation to escape as readily as do the relative level surfaces of the
surrounding countryside. The slow release of heat tends to keep city
temperatures 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 a .....

Using Bicycles As An Alternative To Automobiles
.... investing in their future.
Our Economy is not the only thing we should worry about, and it is also not the
only thing that can be improved by the use of bicycles. There are several major
problems 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 .....

the founder of experimental physiology. During the Renaissance Era, Andreas
Vesalius conducted experiments on monkeys, swine, and goats (1:3). By the late
eighteenth century, the methods of scientific discovery were changer to
experimentation of live animals by two French physiologists, Claude Bernard and
Francious Magnedie. They revolutionized methods of scientific discovery by
establishing live animal as common practice (1:4). Claude Bernard bel .....

Water Pollution

take much garbage with them on their ships and dump them. This was very common
until the government took action. They were giving sailors up to one million
dollars fines for disposing waste. Because of that, ships now carry less garbage
with them.
Animals are not the only thing being harmed by water wastes. Fishing
lines, rope, and plastic nets are being caught in the rutter and the engine, but
the ships are not exactly perfect.

Water Pollution: Is It As Big Of A Problem As We Think?

oxygen to survive. If the oxygen level is depressed to zero, all fish in the
lake die. Any decomposition that does not contain oxygen starts to generate
noxious gases such as Hydrogen Sulfide. Pulp and paper mills, and municipal
sewage causes BOD. Nutrients: Nutrients, particularly nitrogen and phosphorus,
enrich waters and accelerate the aging of lakes and streams. Also, the result
of this is rich plant life which prohibits recreational activities. Plankton

Weather Forecasting

Meteorologists are people who interpret the weather, the reason I don't

information and data at their fingertips, the way that they interpret what is in
front of them can be different. Meteorologists receive information from various
sources, but their interpretation .....

The Wolf

our myths and legends, but if we know only this wolf we do not truly know the
wolf at all. And what we do not know, we fear. Our fear is perhaps the greatest
threat to the survival of the wolf, for it causes us to react rather than act,
to repel rather than respect. But this fear and hatred did not always separate
man and beast
Man the hunter once looked on the wolf the hunter with admiration. Man and

Galileo Galilei "founder Of Modern Experimental Science"

Aristotle. He also invented an instrument that could find the gravity of
objects. This instrument, called a hydrostatic balance, was used by weighing
the objects in water.
Galileo returned to Pisa in 1589 and became a professor in math. He
taught courses in astronomy at the University of Pisa, based on Ptolemy's theory
that the sun and all of the planets move around the earth. Teaching these
courses, he became more understandin .....

Galileo's Hypothesis
Galileo was well known for standing up for what he believed in and
pushing the things he wanted. He was constantly writing letters and engaging in
debates over the issue of Copernicanism. Galileo's entire reason for doing this
was to make t .....
