Today in this world Just about every single major
scientific or technological breakthrough has two sides:
A good side, and a bad side. For instance, Nuclear
Fission/Fusion. The good: We can use it for power. The
Bad: One atomic bomb is devastating to the planet.
Also, the Internet. The good: We can use it to make
purchases, do research, and share our views and
opinions. The bad: It be used for identity theft, scams,
and porn. The bad edge of science hasn't killed us yet,
but when a crazy enough dictator gets his hands on
said technology, the world as we know it will have
Science as destroyer by war
‘Regional’ Nuclear War Would Cause Worldwide Destruction
Beyond the local human tragedy of such a situation, a new
study looking at the atmospheric chemistry of regional
nuclear war finds that the hot smoke from burning cities
would tear holes in the ozone layer of the Earth. The
increased UV radiation resulting from the ozone loss could
more than double DNA damage, and increase cancer rates
across North America and Eurasia.
"Our research supports that there would be worldwide
destruction," said Michael Mills, co-author of the study and
a research scientist at the University of Colorado at
Boulder. "It demonstrates that a small-scale regional
conflict is capable of triggering larger ozone losses globally
than the ones that were previously predicted for a full-scale
Combined with the climatic impact of a regional nuclear war — which could
reduce crop yields andstarve hundreds of millions — Mills’
modeling shows that the entire globe would feel the repercussions of a hundred
nuclear detonations, a small fraction of just the U.S. stockpile. After decades of
Cold War research into the impacts that a full-blown war between the Soviet Union
and the United States would have had on the globe, recent work has focused on
regional nuclear wars, which are seen as more likely than all-out nuclear
Armageddon. Incorporating the latest atmospheric modeling, the scientists are
finding that even a small nuclear conflict would wreak havoc on the global
environment (.pdf) — cooling it twice as much as it’s heated over the last century
— and on the structure of the atmosphere itself.
Mills’ work, which appears online today in the Proceedings of the National
Academies of Science, useda model from National Center for Atmospheric
Research to look at the impact of throwing 5 million metric tons of black carbon,
or soot, into the atmosphere. He found that when a cluster of cities are burning
together, they end up creating their own weather, pumping soot 20,000 feet into
the atmosphere. Once there, sunlight would heat the smoke, and drive it up
260,000 feet above the earth’s surface.
Along the way, the hot soot would cause a variety of atmospheric changes with a
net result of huge reductions in ozone, which in the stratosphere serves as
sunblock for the earth. In the middle latitudes, the researchers found the ozone
layer would be reduced by 25 to 45 percent, with the polar regions losing 50 to 70
percent of their ozone coverage. This thinning is known as a "hole" in the ozone
layer, and would be many times the size of the famed hole over Antarctica.

Today we all are watching what Science has done to our nature. The hole in

down. So why aren't governments doing more to protect the environment?
We've long known that environmental factors contribute to disease, especially
contamination of air, water, and soil. Scientists are now learning the connection

New research shows that 60 per cent of emerging infectious diseases affecting
humans — those that rapidly increase in incidence or geographic range — start
with animals, two thirds from wild animals. Lyme disease, West Nile virus,
Ebola, SARS, AIDS... these are just a few of the hundreds of epidemics that
have spread from animals to people. A study by the International Livestock
Research Institute concludes that more than two-million people a year are killed
by diseases that originated with wild and domestic animals. Many more become

At last Science as a Mankind
Scientific discoveries and inventions has made the life of men
easier and smoother. In the earlier days men had to undertake
very hard jobs as scientific devices and technical know-how was
not available. Besides hard work, the process of productions was
very slow. Thus, most of the wants of men remain unfulfilled.
With the passage of time, education and knowledge developed.
Men concentrated more and more on the study and application of
the know-how of science. Emphasis was laid on the study of
science. Rigorous study and research of science resulted in
numerous scientific inventions that resulted in the application of
scientific methods in different aspects of life. Now there is hardly
any aspect of life in which science and scientific techniques are
All the items of comfort and luxury is produced through the use of
scientific knowledge,machines and better production methods.
