Environment I
Greetings,
The past few weeks we have devoted to the subject of pollutants.
Rather a gloomy subject! Let’s see how we can do our bit to help
the environment.
One of the primary requisites for healthy and long life is clean
and pure air.
Unfortunately, this is one area that we sometimes have little control
over. We can always choose the food we want to eat and decide when
to exercise or fast, but the air we have to breath is what is given
us.
However, we are not entirely helpless. Here are a few suggestions
that will help us live in a cleaner environment.
1- Reduce your fuel consumption and car dependency.
2- Use unleaded petrol
3- Have your car checked to see if it is emitting high levels
of pollutants.
4- Allow no smoking in your personal environment
5- If you are moving home look for a house that is away from high
traffic roads and highways.
6- Follow a non-toxic diet in order not to load the body with
chemicals
7- Exercise away from heavy traffic areas. Do not run alongside
cars while jogging, and save all heavy exercising for as unpolluted
an area as available to you.
8- Purchase products, which produce little pollutants in their
manufacture. Some of the worse pollutants are plastic industries and
petroleum companies. Try to restrict the use of such products.
9- Plants and forests are our first line of defence against air
pollution. Let’s help by planting trees in our gardens and preserve
the existing ones
10- Minimise open fires and coal burning in winter.
Every day of our lives we draw in 20.000 breaths. We have the right
to expect that not a single one of these breaths endanger our health.
The air and atmosphere are our common heritage and resource, and we
must insure that they stay clean for us and our children.
A FEW INTERESTING FACTS ON SOLAR ENERGY:
-All energy on earth originally comes from the sun. All of our
hydrocarbon fuels such as coal, oil, and natural gas were originally
produced by the action of sunlight on vegetation.
-The concept behind solar energy use is not new. Legend has it that
in 212 B.C. Archimedes set fire to an attacking Roman fleet by turning
a "burning glass" composed of small, hinged square mirrors so as to
reflect concentrated sunlight onto the ship. For years scientists argued
about whether this was myth or fact, but in 1747 a Frenchman proved that
it could have been done by burning wood from a distance of 200 feet with
an array of 168 small flat mirrors, and then melted lead at 130 feet and
silver at 60 feet. In the same century, an optician in France built
polished iron solar furnaces that could smelt iron, copper, and other
metals. Another investor used 2 lenses to achieve a temperature close
to 1750 degrees Fahrenheit- far beyond any temperature attained by man
up to this time.
In the 1800s came many models of solar powered engines and solar steam
engines. In 1871, a solar still in Chile provided 6.000 gallons of pure
water a day for 40 years. In 1880, a solar engine was built in France
that ran a printing press.
Of course, foods have been sun-dried for ages, using solar power
without the need for technology. In the early 1900s, solar oven
appeared.
Solar water heaters were known in southern California and other states
in the 1920s and 30s. After World War II, solar sciences flourished in
Europe and a boom in solar water heaters began in Japan and Israel.
Heaters were installed by the 100.000’s in Japan.
The advantages of using solar energy are numerous; it is renewable and
limitless and promises freedom from dependency on non-renewable energy
sources, thus freeing mankind from the threat of war over dwindling
natural resources. It is clean, non-polluting and safe.
At the moment about 80% of the world’s energy comes from fossil fuels,
about 20% from dung and vegetable wastes, and about 1% from water power.
A few rich countries, representing less than 30% of the world’s
population, consume about 75% of the world’s energy
Aside from the fact that non-renewable energy sources are in limited
supplies, the main reason for not using them is the pollution, health
and safety risks involved. Some say there are "three environmental
time bombs": toxic chemical pollution, carbon dioxide (CO2) build-up,
and acid rain.
Makes us think doesn’t it?
Until next week, take care,
