Ozone Depletion
.... together
and cannot be broken down by water. This means they travel into the atmosphere
virtually unharmed by rain or decomposition (Goldfarb 282).
The reason these are causing such a commotion is the damage they cause
to living things on Earth. When the ozone depletes, it causes more ultraviolet
(UV) rays to hit the Earth's surface than are healthy (Singer and Crandall npg).
UV rays affect the DNA of every living cell, altering the protein make-up of
that cell (Goldfarb 288). Most importantly it .....

Plastic Not Paper
.... about a big waste of gas. Plastic bags cost
about ¼ of a cent to make, while paper cost close to 3 cents. This is money we
save as well as the store owner. This is a lot of money that is going to
waste considering that plastic bags are so much more practical then paper. You
can use them for lots of other things. You can take on trips to the grocery
store, your can protect dry clothing from wet towels in an exercise bag. You
can line your house hold waste basket with them, you tote dry shoes to wor .....

"An Ecosystem's Disturbance By A Pollutant
.... and population.
Pollutants can affect both a population and an ecosystem. A pollutant on a
population level can be either non-target or target. Target effects are those
that can kill off the entire population. Non-target effects are those that
effects a significant number of individuals and spreads over to other
individuals, such is the case when crop dusters spread herbicides, insecticides.
Next we look at population damage by a pollutant, which in turn has a
detrimental effect on the ecosystem .....

The China Syndrome
.... He tried to explain that there could be
another accident if they raised the power all the way because of a problem with
the pumps. The people didn't believe Jack and were starting to raise the power
up again. When Jack saw what they were doing he grabbed the security officer's
gun and forced everyone out of the control room. After he locked the door he
lowered the power down to 75% so the pumps wouldn't break.
Jack agreed to have a one on one interview with Kimberly so the public
would be warned. While t .....

Ehrlich's Population Bomb
.... Paraphrasing Ehrlich's ideas in chapter can
be explained as; there is only so many resources and as population increases
those resources will soon be depleted. Ehrlich uses historical population
research to lead to the conclusion that in 90 years the population could be well
over the earths carrying capacity. In third world countries where population
control is rarely used population, pollution, and scarcity are becoming ever
increasing problems. Roughly 40% of the population in third world count .....

Fusion
.... "What is fusion?" One simple way of explaining it is
taking two balls of clay and mashing them into one, creating a new, larger
particle from the two. Now replace those balls of clay with sub-atomic
particles, and when they meld, release an enormous amount of energy. This is
fusion. There is currently three known variations of fusion: the proton-proton
reaction (Figure 1.1), the carbon cycle (Figure 1.2), and the triple-alpha
process (Figure 1.3). In the proton-proton reaction, a proton (the positi .....

The Potential Effects Of A Depleted Ozone Layer - Detrykowski
.... to man - made chemicals (
Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are
released, "the ozone layer would be weakened to such an extent that it does not
filter 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 .....

Predators And Ecosystem Management
.... it was possible to gain much insight into the sea
otter ecological role in kelp-forest ecosystem. Over the years it's been
possible for us to observe the kelp-forest ecosystem over-time, thanks to the
massive growth of the sea otters population we observed the change from otter-
free to otter-dominated.
This article relates to many aspects of our textbook. On page 89 in
chapter 5 the text explains what an ecosystem is, defined by the book, it's a
community of species interacting with one another where t .....

Privately Owned Gasoline Powered Vehicles Should Be Limited
.... Automobiles run on gasoline, which
is a mixture derived from petroleum. Gasoline contains hundreds of different
hydrocarbons, or compounds containing the chemical elements carbon and
hydrogen(Gasoline). When the gas is burned in the engine of the car, several
byproducts result. These exhausts include hydrocarbons and oxides of three
elements: Carbon, nitrogen, and sulfur(Emissions). Tiny amounts of poisonous
trace elements such as lead, cadmium, and nickel also are present. Everything

Purple Loosestrife

found in sheep and livestock feed that was imported from Europe during this
period. This new organism was introduced to a new habitat free from traditional
parasites, predators and competitors, purple loosestrife thrived in the
environmental conditions and by 1880 was rapidly spreading north and west
through the canal and marine routes. Purple loosestrife stands also increased
due to the importation of seeds and root stalks by horticulturists. It was
introduced to many communities as an her .....

Radon

health hazard. Some wells contain water that has radon dissolved in it. This
can be a hazard if the water is agitated or heated, allowing the gas to escape
and elevate the levels that are in the building.(6)
Health Risk
The Surgeon General's office reports that indoor radon gas is a national
health problem. This gas causes thousands of deaths every year.(7) These
deaths are a result of lung cancer, which is caused by the radioactive particles
that make up the gas.(8) The likelih .....

85 countries all over the world, however, 90 percent of them are concentrated
into fifteen countries, each containing over ten million hectares. Tropical
rainforests receive 160 to 400 inches of rain each year. Although these dense,
damp forests cover just 5 percent of the Earth's surface, they can provide homes
for between 50 and 90 percent of the Earth's plants and animals

Recommendation For Recycling Water In Florida
.... increasing occurrence of sinkholes, the evidence of a water
shortage is everywhere. Since we need water to survive, and there are no
alternatives to support life on this planet, we must find a way to keep up with
our ever increasing water demand.
This report presents the water shortage problem that is occurring in
Florida. This report will familiarize you with the problem and explain the
other uses currently being employed in Florida. This report also explains the
procedure, as well as a recommendatio .....

Reforestation
.... that new trees pull the carbon dioxide better than old trees, and this may
seem true, but it is not. There is one point being overlooked from all of this.
The older, larger trees can store much, much more carbon dioxide than a new tree
could. By cutting and burning these magnificent seasoned trees, the CO2 is
being released back into the atmosphere. These releases of carbon dioxide add
up in our surroundings, only to intensify Global Warming. Although this shows
what happens when one burns and cut .....

Role Of Government Intervention In Environmental Issues
.... issue becomes
the fact no matter what, there will always be pollution, as long as these
industries exist. So we should focus on how we can minimize this and yet at the
same time have an efficient market system? Furthermore, we should also focus on
how we can accomplish this so that sustainable growth and development can take
place. So there is definitely a need for some form of government intervention
to enforce and monitor this. Reason being that there is always an element of
equality that has to .....
