Turn off your computer
Turn off your computer if you are
not using it for 1 hour or more and help reducing global warming. What is the
connection between your computer and global warming? Carbon dioxide emission
into the atmosphere is the main cause of global warming.
One computer left on for 24 hours a
day will result in the emission of 1,500 pounds of Carbon Dioxide into the
atmosphere in a year. A tree absorbs nearly 10 pounds of CO2 each year. So, we
need at least 150 trees to offset the carbon emissions from one computer left
on always.
World Environment Day is being
observed on June 5th 2012. “Green Economy: Does it include you?”
is the theme of this year’s conference. The focus of this UN sponsored annual
event is on reducing CO2 emission, and global warming. At present, this is
literally the most “Hot” topic discussed all over the world by
environmentalists.
Al Gore, former Vice President of
USA and Dr.Pachauri, a leading scientist from India, had won Nobel Prize for
their contributions in this area.
Why global warming is such an
important issue?
The main consequences of global
warming normally would result from – Rise in sea level, Increase in local
temperatures, and changes in rainfall patterns. These are mainly attributed to
increased population densities and human activities including lifestyle that
contribute for CO2 emission to the atmosphere.
These factors may lead to extreme
and catastrophic weather conditions. Unprecedented heavy rains, hurricanes and
melting of polar glaciers are some of the extreme weather conditions that have
already started happening. At the current rate of melting of ice, the world may
witness a North Pole without any covering of ice in the near future. This will
have far reaching implications.
Some of the effects of global
warming will be abrupt and irreversible. If the global average warming exceeds
around 3.5% there will be significant extinctions of life. It is projected up
to 70% of the species will be extinct. Rising temperatures already have
noticeable impact on birds. This will also have adverse effect on our
ecosystem.
Rising sea level is another serious
danger. If the level of rising continues in the present rate, very soon most
part of the low-lying countries such as Maldives, Netherlands and Bangladesh
will be under water. Some of the island countries in the pacific region will be
erased out of the world map.
There will be significant impact on human
health, which includes cardio vascular problems, lung diseases and spread of
dreaded diseases such as SARS, dengue, and Malaria etc. Warmer climate will be
conducive for the spread of such diseases. Malaria is now widely seen mainly in
Africa. But thanks to global warming it has already started appearing in
Western Europe, South America and Russia.
The geographic impact of global
warming is more catastrophic in scale. Presently, Greenland is melting at a
rate of 52 cubic miles per year. If the entire ice in Greenland were to melt,
it would lead to a global sea level rise of more than 23 feet.
Oceans absorb CO2, and when it is
mixed with seawater, it results in the production of carbonic acid. At present
nature has provided calcium from eroded rocks creating a natural protection
against this acid. As more and more CO2 is produced this balance will be thrown
out of gear and the oceans will turn into acid.
The Gangotri glacier of Himalayas,
that provides 70% of the water to river Ganges, is shrinking very fast due to
global warming. So the sacred river of India, which provides water for
drinking and farming to nearly 400 million people, faces the danger of drying
up.
The scenario is scary.
It is too scary, but not hopeless.
If we follow a simple Eco-friendly
lifestyle we can help improve our environment.
- Turning off your TV, Computer, DVD Player and Audio system when you are not using them will prevent thousands of pounds of Carbon Dioxide polluting the environment
- Use less hot water, since heating water consumes a lot of energy, which in turn results in considerable CO2 emission
- Keep the tires of your vehicle in properly inflated condition. This improves mileage by at least 3%. Every liter of patrol saved keeps 4 pounds of CO2 out of atmosphere
- Thousands of pounds of CO2 can be reduced if you reduce your garbage by 10%
- Every single tree is capable of absorbing more than a ton of CO2 in its lifetime.
So, let each one of us try to plant
at least one tree.
The above list is not complete. You
can do a lot more to save this planet, our only home in this universe. At least
we can try to give our children a safe place to live in.
