Why
do we need to save
trees?
All living things
depend on trees directly or indirectly. Our beautiful planet Earth would
not survive without trees. Life as we know it would not exist without
trees. This shows the importance of trees to our lives. We humans who
heavily depend on trees do not realize that we are threatening our very
existence when we go cutting down trees, may it be for necessary, or
selfish needs. Some of us do not stop to think how our actions are
destroying the planet Earth, our home. Deforestation at the current rate
would soon leave our mother Earth a barren and desolate place. Hence,
going green by protecting and planting trees is essential for our
existence. As we emphasize on the need for saving trees, here are five
reasons why we need to protect trees.
Trees
provide vital oxygen.
Trees, like other members in the plant kingdom produce their own food using the process of photosynthesis. In this natural process, trees take up Carbondioxide from the atmosphere and release Oxygen as a by-product. The more trees present, the more Oxygen plants will release. We would not survive without oxygen. This is the most important reason why we need to save as many trees as possible. The following equation shows how the process of photosynthesis takes place.
Carbondioxide + water
--------------> Glucose + Oxygen
Trees help moderate the
climate.
Trees regulate
the climate by moderating rain, wind and reflecting or absorbing solar
radiation. Trees cool our environment and shade us from the burning rays
of the sun. In the vicinity of trees the temperature is kept in check.
An area can get heated up and very hot when there are no trees present.
Evaporation of water from trees causes cloudiness. As clouds can deflect
sunlight, trees are indirectly reducing the heat in an area. Trees catch
the rain and deflect hail and sleet; it is a form of protection provided
by trees. Trees affect the direction and speed of wind. The wind
breaking effect of trees is much higher when there are more trees
present.
Trees
clean the air we breathe.
Trees absorb
pollutants such as Carbon monoxide, Sulphur dioxide and Nitrogen dioxide
in the air. By trapping particles such as dust, smoke, ash and pollen,
trees clean the air we breathe. Clean air is necessary for us as
breathing polluted air leads to many health problems including allergies
and respiratory disorders. Air pollution is further reduced by trees as
they lower the air temperature through respiration. If we have more
trees, the air we breathe will be cleaner. Those plants we grow for
decorative purposes are providing us clean air.
Trees prevent global
warming.
The rising
trend in atmospheric Carbondioxde, a greenhouse gas, is highly
associated with global warming due to the greenhouse effect. Trees help
prevent global warming by reducing the levels of Carbondioxde in the air
and acting as carbon sinks. During photosynthesis, trees absorb
Carbondioxide from the air and store it in the form of sugars. As
Carbondioxde is locked away in plants, it is no longer available as a
greenhouse gas. Since clouds reflect solar radiation, there will be less
heat. This way trees are indirectly preventing the greenhouse effect and
hence global warming.
Trees prevent
flooding.
During rainy
season surface runoff causes inland water bodies such as rivers and
lakes to overflow and flood. Trees absorb water which prevents flooding.
Trees present near a water body slow down the runoff and give water more
time to be absorbed into the ground. In rocky areas, roots from the
trees break up rocks and create spaces allowing the flow of water, thus
preventing the chances of flooding in nearby lakes or rivers. When trees
are not available to hold the runoff water, floods become more likely in
an area.
