A Glance at Deforestation
By June Narber Harrison
Forests are among Earths most important
ecosystems. What many people do not realize, is that many of Earths ecosystems are
inter-related. The oxygen in the atmosphere, the waters of the ocean, and the living
plants and trees interplay on each other to sustain their cycles, keeping their internal
living creatures fed and alive. When one element is altered in any ecosystem, all others
have the potential of being affected.
If toxic chemicals are sprayed on crops, they seem into
ground water (and then drank by humans, and absorbed into surrounding flora). Animals then
eat the crops in turn, being eaten by humans. Any way it is looked at, the toxic chemicals
end up in our own cell structure. Many of the cancers and illnesses we face today can be
linked to pesticides, fertilizers and herbicides.
The forests of earth are complex in their composition. The
rain forests of Brazil offer the most lush and varied flora and fauna to be found anywhere
in the world today. However, it is being deforested at an alarming rate. When large parts
of a forest are cut down, without careful planning, many other internal microecosystems
are disrupted.
What Causes Deforestation?
Deforestation is caused by over cutting of the trees by
large timber companies; slash and burn (called swidden horticulture) cultivation of native
peoples (this is found today in many developing nations). Commercial development is the
leading world wide cause (mineral and oil exploration; burning down of huge forest areas
for cattle production; and urban development, infrastructure development such as roads;
Deforestation is a result of careless planning and not taking necessary precautions to
protect the forests to guarantee their survival as a resource for future generations.
Can the worlds forests survive the intrusion of man?
As Christians, we can rationalize that God gave us the world to rule over. However, with
rulership, comes great responsibility to do it properly. Mankind was made the husbandman
of the earth. That did not give him license to kill and destroy recklessly. With the
earths population doubling every nearly every twenty years, we have to realize that
means more mouths to feed and more natural resources will be used up. The earth can only
produce so much wood and other products per generation. What if the need and usage
outweighs the production? What if so much of earths forests are cut for fuel and
by-products, that not enough trees are left or replanted to replenish the forests for the
next generation? That is exactly what is now happening.
Without the forests, especially the tropical rain forests,
the oxygen levels of the world could not exist! The ozone layer and other ecosystems of
earth are directly affected by the health of the worlds forests. Only during the
last decade have scientists began to view the different ecosystems of Earth as part of a
giant whole. Prior, they thought of each ecosystem existing apart from the others.
However, with the devastating effects that needless pollution, ozone layer depletion and
other chronic manifestations of a sick planet. Scientists finally began to realize that
the oceans, atmosphere, land and forests ecosystems interact with each other to produce
the oxygen and nutrient rich planet that we call home. We have to remember that God
created a balance in the Earths natural cycles. When we pollute and destroy, we are
upsetting the structure God ordained. In turn, we will have to face the physical
consequences. Among these many consequences are chronic worldwide pollution, new deadly
disease strains, reduced crops, changed weather patterns, and altered ecosystem
biodiversity.
Consequences of deforestation
In economic terms, the tropical forests that are destroyed
worldwide represent a loss in forest capital of 45 billion US dollars. By destroying
forests, all potential future revenues and future employment derived from their
sustainable management for timber and non-timber products vanish. Biodiversity (the
variety of different animal and plant species) is also severely reduced. In many cases,
the actual extinction of thousands of varieties of plants and animals is a result (many of
which never have been scientifically classified or studied yet!) Estimates put the annual
average of loss of biodiversity at 50,000 separate species (including flora and fauna).
Youve probably heard of global warming. There is
debate over this theory, but the evidence is that the polar caps are getting warmer, and
world temperatures are shifting. The worlds ocean temperatures are rising. What does
this all mean? Global warming influences the world weather conditions. This leads to
droughts in one part of the world and severe flooding in other. In turn, famine from
ruined crops. It has been proven that deforestation is a leading cause in global warming,
however, not a sole or only cause. The principal cause of global warming is the discharges
from burning fossilized fuels from the developed countries.
Another thing to consider is that deforestation causes soil
erosion (increasing its compaction where crops cannot grow therein, leeching out of its
nutrients, increasing the aluminum toxicity of the soil). This leads to soil marginal for
crop production.
With less forests, and more demand for its products (mainly
timber and fuel-wood), the result is a shortage of a needed human resource.
Points to Ponder:
- You can make a difference by not wasting paper and other
forest produced resources.
- You can support local efforts to protect national forests in
your area.
- Refuse to buy products that were produced or taken from
tropical rainforests, especially from Brazil.
- Participate in planting trees for future generations in your
area.
- Plant a tree for every one you cut down for personal use.
- Learn careful cutting techniques if you cut wood, so that
you do not damage surrounding trees, and you leave enough cuttings to allow proper
reforestation.
- Dont use paper products that can be avoided, such as
paper bags from the grocer: buy a cloth sack to put your groceries in. Dont use
paper plates that are thrown away after one use. Concern on your paper usage, like writing
on both sides of a piece of stationary or printing on both sides of a page from a printer
or copying machine.
- Recycle everything that you can including paper products,
metals, and glass.
- Dont support large enterprises that are responsible
for destroying the rain forests of South America. Listings of these companies are
available through many different non-profit organizations and the Internet.
- Go to your library and read about these problems and educate
yourself about the the worlds resources and forestry trends.
- Teach your children to respect nature and how to conserve
resources.
Realize that deforestation is a really serious problem and
that it need immediate and international directed attention. No matter how long we have
before the return of Christ to rule all nations, we have to live on the planet and we want
it to be as fruitful and beautiful as we, and our forefathers have enjoyed.
