The African Penguin

... large
but some man caused factors has drastically reduced their species. A long
time ago the early European settlers at the Cape of Good Hope realized that
penguin eggs were good for eating and over the years millions of penguin
eggs have been collected greatly reducing the population of the African
penguin species, and even to make things worse they started the practice of
destroying any incubated eggs so that there would be fresh ones when these
collectors paid their next visit. Another reason the African Penguin
population was decreasing is Guano on the islands on which the penguins
breed. I ...

The Greenhouse Effect
Number of Words: 463 / Number of Pages: 2
... are not as damaging in the long run.
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 e ...

Star Mars

... information about the red planet
because of the vast distance between us.
While people such as Steven Spielberg and George Lucas try to convince
us with hundred million dollar movies that we are not alone, engineers and
geologists like from the NASA-Stanford University team pursue, based on true
evidence, the idea of possible life on Mars. However, the burden of proof is
sometimes too heavy even based on real evidence. The tough debate started on
August 1996, when scientists from the NASA-SU team announced that a meteorite
found on the Antartica contained evidence of past life on the red planet. Th ...

Do UFOs Exist?
Number of Words: 652 / Number of Pages: 3
... to be provided.
The Roswell incident is now generally regarded as one of the most
important UFO events in history, an extensive review of the UFO literature of
the 1950s finds no mention of it beyond the first press accounts in early July
1947. The only know reference to it as a UFO crash was in a 1955 lecture by
broadcaster and UFO enthusiast Frank Edward. Even in the 1960s the UFO
literature mentioned it only three times, twice in both brief instances, in the
latter rather vaguely. A widely published story reported that personnel from
Roswell Field had a "flying disk" in their possession. Whe ...

... with Oxygen, water, acids, and bases it is compounded
with other metals and elements to from alloys for common uses. In Society
Aluminum Alloys are used in many ways because of it's light weight and
versatility. As more and more ways are discovered to strengthened Aluminum
with other elements more uses have also been discovered Aluminum is used in
aircrafts, Electrical Engineering, Windows, doors, buildings, packaging and
many other things. When aluminum is compounded with other it gets stronger
for multiple uses. It is usually is compounded with copper, magnesium
silicon, zinc, oxygen, and pota ...

Cloning

... created a lamb (Dolly), the
topic of cloning "created" many new questions of its own. None were as
controversial as: Will they apply this to humans as well? According to Dr.
Wilmut, the answer was "there is no reason in principle why you couldn't do
it"(clone humans), but he added, "All of us would find that offensive."(Wilmut
as quoted by NYTimes, Daniel Callahan, 02/26/97).
From an individualistic viewpoint, those in favor of cloning human
beings, do not see it as morally, or ethically wrong. Many see it as an
opportunity to have children, or possibly to "re-create" a child who is dying ...

UFOs Exist
Number of Words: 1801 / Number of Pages: 7
... people all over the world. Ufologists have come up with a system to divide UFO incidents into three major types of close encounters.
First, close encounter of the first kind (CEI) are classified as UFO sightings. Second, close encounters of the second kind (CE2) are sightings and permanent evidence, such as marks in the ground or burns on grass. Third, close encounters of the third kind (CE3) are actual contact with alien beings from a UFO. (Oberg 240)
There are many different theories about how UFOs travel and where they come from. "Some scientists believe that they come from the larger planet ...

Chemical Bonding

... light and heat are given off. This shows an exothermic reaction, which is a release of energy. The electrostatic energy between the two holds them together. Ionic bonds are useful because in a liquid state it can conduct electricity. This is possible because it contains ions. That doesn't conduct electricity in the solid state because there is not enough room within the molecule. The substance produced by this bond is table salt. Other salts, such as CaCl (rock salt) are formed in the same way and although they have a different crystalline structure they do possess the same physical properties.

... trade deficit.
The future looks even better. Advanced-design nuclear power plants are now being developed—quicker and less costly to build, better performing, and even safer than today's plants. These plants will supply our children's and grandchildren's electricity—while helping to protect their environment.
Cheers For Energy Efficiency
We Americans should be proud of ourselves. Since the 1973 oil embargo, we've learned to use energy far more efficiently.
Since 1973, our population has soared from 211 million to more than 258 million, and our economy has grown about 50 percent ...

Genetic Engineering: A Leap In To The Future Or A Leap Towards Destruction
Number of Words: 3028 / Number of Pages: 12
... it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted.
The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of nature's evolutionary process when an Austrian monk named Gregor Mendel developed the first "laws of heredity." Using these laws, scientists studied ...
