Protecting our environment and natural resources

from July 14
Scientific research confirms that the earth we live in is a unique
planet with a balanced environment, which has enabled a wide range of
life forms to develop and survive and that of the millions of stars and
planets located in our solar system, our earth is the only one having
the conditions necessary for survival of any life whether animal or
plant. The many religions which modern humans believe in, date from a
few thousands of years ago and vary in a few details, but we are not
herein interested in any discussion on such spiritual beliefs which we
respect as every human’s right to accept or not.

Our concern is on the physical factors which involve the environment
we live in and matters related to the inter relationship between the
total environment of the planet, its ongoing changes and effects of such
changes on life forms ranging from the smallest algae to trees,
categorized as flora, and animals large and small categorized as fauna.
We humans, who are a highly developed animal, belongs to the category or
fauna.
Unlike the large number of other planets in our universe, planet
earth has developed into a balanced ecological system, with all
requirements for life to exist in.
This process has taken billions of years and the life forms developed
parallel with the changes which have occurred from it’s origin or
prehistoric period, to what we call the modern world. Scientific
evidence of research proves that there have been environmental upheavals
even in prehistoric times with catastrophic impacts, including
temperature changes referred to ice ages and heat waves, continuous
rains and floods huge volcanic eruptions, earth quakes and sixty five
million years ago an impact of a large meteorite changed the primeval
climate of that time so drastically, that most life forms of the period,
ranging from small mammals to large dinosaurs got extinct, and new life
forms developed for millions of years, to once again inhabit the earth.
The planet we live in, our mother earth, has been comparatively
stable for thousands of years and finally reached a stage of
environmental development suitable for life of today’s flora and fauna
including humans to survive in.
There have been environmental upheavals during the last few ages
during which period most modern life forms developed, but the existence
of natural resources which developed and co-existed with other life
forms enabled nature to survive and adjust after such upheavals and for
life forms to continue and develop.
Natural resources
The great difference now is that mankind has destroyed the earth’s
natural balance by destroying natural resources and increasing
atmospheric as well as water and land surface pollution creating
problems the world faces, including causes and affects.
The earth and its life forms as traced by scientific research and
accepted today, have been quite stable for thousands of years, with the
strength to adjust and recover from the occasional environmental changes
that occurred, because of the balance between life forms and the natural
resources that life depended on. From primitive to modern humans, right
up to a few hundred years ago, this important natural balance continued,
and resulted in a comparatively stable temperature, clean water and
fresh air, good earth, forest cover and inter related life forms,
providing essential food chains and resources required.
This balance and protection of natural resources is referred to by
all humans ranging from the primitive tribal leaders to great religious
leaders venerated for thousands of years and whose teachings covered the
need to protect and preserve natural resources as gifts of the super
natural.
Global environment
The stark reality we humans of today have to accept, is the fact that
the steady balance of a healthy global environment which has lasted for
millions of years, has been destroyed by modern humans within a short
period of just over a hundred years.
Humans evolved about thirty thousands years ago and developed
physically and mentally to reach the status of early intelligent man,
homo sapiens. With the growth of their wisdom and their understanding of
the need to protect natural resources, they harvested the fruits of
nature leaving natural resources for their progeny to continue
harvesting.
Wealth and power
The destruction which commenced during the lifetime of a few elders
still alive and of parents of today’s youth, continues unabated and has
resulted in the danger of our own children, grand children and great
grand children, having to face unprecedented environmental
deterioration, shortages of food and more seriously the affects of such
deterioration.
The greed for better life styles of today’s adults, for more wealth
and power of individuals and nations, has triggered off a virtually
irreversible chain of environmental degradation and imbalance that will
have to be paid for by our progeny, including the youth of today.
It is a tragic reality that these dangers are known to most adults,
at least the intelligent and educated adults and by most leaders of
countries and specially the developed countries, which are responsible
for the global environmental dangers, but they delay taking any action
to at least mitigate the dangers we face, as their thinking is limited
to the power wealth and comfort of their life spans and do not wish to
risk their present lifestyles even for the sake of the future of their
own progeny.
Some in their greed and selfishness convince themselves and the
society around them that there is time for them to act and that
something will happen during such time to reverse the predicted
environmental trends.
Subsequent articles of this series which will be continued regularly
as a joint environmental service program by the Associated Newspapers of
Ceylon Ltd. and the Lanka Initiative for Flora and Environmental
L.I.F.E., will deal with all the related subjects which form a part of
the total environmental problem, collectively described as Global
Warming and the Sea Level Rise. A brief reference is made in this
article to indicate the connected subjects which will be covered in
detail.
The main cause of the problem is the massive environmental pollution
caused by burning of fossil fuels in factories and vehicles coupled with
deforestation, which reduces the only natural resource which can absorb
the increasing amounts of carbon dioxide, spewed into the atmosphere by
use of fossil fuels and excessive burning of coal.
Bottled water
Shortages of pure water, which is essential for survival is a serious
threat to all life forms, including us humans and is caused by pollution
due to excessive use of agro-chemicals, coupled with overuse, wastage
and poisoning of ground water and the new easy way out by use of bottled
water instead of finding ways to clean available water by old
traditional methods. Increased demand caused by increasing population
and greater per capita usage threatens our natural balances.
Pollution of our oceans is as serious a subject as any land-based
pollution discussed. Of the green plant life that contributes to
cleansing of our atmosphere by absorbing and holding the carbonic
emissions from all sources, algae in the oceans are the greatest
contributor to this essential process of photosynthesis.
Oil spills
Oceans are now threatened with serious degradation by oil spills and
oil discharges from ships and also from land based sources including
garbage and refuse dumping directly to the seas or to rivers and streams
which flow into the seas carrying harmful chemicals which are carried by
rivers and streams.
The problems is made more acute due to the effect of global warming
caused by human activities and scientific studies show that large
extends of coral and micro marine life is seriously endangered due to
warming of the oceans and land based pollution.
The destruction of corals and marine micro organisms will triggers
off a serious impact on the marine food chain which will result in a
depletion of fish and other sea foods. |
