you ever wondered what a world without trees would look like? Close your eyes,
and try to imagine a desolate earth. Yet on such a dry, lifeless world, no one
would be left to experience the disastrous consequences of deforestation. It is
estimated in one hundred years later, there will be no rainforests at all.
There are several adverse effects of deforestation that can destroy the
ecosystem such as global warming, soil erosion and loss of habitat.
Global warming is the increase in temperature
of the earth’s surface and atmosphere.
According to Naseem (2011), the dirty that is caused by airborne
particles and pollutants such as carbon monoxide, sulphur dioxide and nitrogen
dioxide also may cause warmer air up to 11.1 C. Trees balance the amount of
carbon in the atmosphere through the photosynthesis process. According to
Hilderman (2012), disruption of the photosynthetic activity which will result
in the increase amount of carbon dioxide in the atmosphere may occur due to the
absence of the trees. Deforestation has an effect on the carbon cycle, also
known as the greenhouse gas effect. Deforestation cause the increasing quantity
of greenhouse gases in the atmosphere which lead to global warming. Michael
Daley, the associate professor of environmental science at Lasell College in
Newton agrees that the top trouble when humans keep cutting down the trees is
the effect on the global carbon cycle (Bradford, 2015). When abnormally high
levels of greenhouse gases accumulate in the air, the temperature increased.
According to Asdrasko, about 25% of carbon dioxide released from combustion of
fossil fuels is equivalent to the amount of carbon dioxide released due to
global deforestation (Chakravarty, Ghosh, Suresh, Dey Shukla, 2012).
of trees may speed the process of soil erosion. Due to deforestation, millions
of hectares of land have become unproductive and barren. The land will yield
crops for only a few years and they will become waste land when the nutrients
are no longer sufficient to be used if deforestation occurs for cropland
(Hilderman, 2010). Next, soil erosion may affect the downstream waterways where
the soil that is carried away is deposited. According to Bradford (2015), soil
disintegration could additionally prompt residue entering those lakes, streams
and also other water sources. The carried soil will result in siltation of the
water storage and watercourses. When the plants are planted in that area, soil
erosion carries them away leaving the soil bare.Since 1960, the WWF states that scientists estimate
that due to deforestation about a third of the world’s arable land has been
lost (Bradford, 2015).
Due to cut down of trees, the soil will lose its protection since the soil
exposed directly to the harmful substances. According to Naseem (2011), without
trees there is no filtration that could lead to the accumulation of dangerous
toxic substances and pollutants. Hence, the soil erosion will become more
prevalent due to the low soil structure and quality.
deforestation may contribute to the loss of habitat in the world. As we know,
rainforests contain the highest level of biodiversity in the world, and without
a diverse world, life will be unable to thrive. Absence of forests’
cover and loss of biodiversity could trigger unexpected, irreversible and
negative changes towards the environment (Chakravarty, Ghosh, Suresh, Dey &
Shukla, 2012). Tropic forests are responsible as storehouses of biodiversity
but deforestation, fragmentation and degradation will damage the whole
biodiversity and habitat for migratory species including the ones which
seriously at risk of extinction and some of which have still to be list (Chakravarty,
Ghosh, Suresh, Dey & Shukla, 2012). Many statistics show that deforestation
is one of the causes of loss of habitat. According to National Geographic,
deforestation caused about seventy percent of the world’s plants and animal
live in forest losing their habitat (Bradford, 2015). If we not take action
from now, Sumatran Tiger, Orang utan, Rhinoceros, Malayan Sun Bear, Giant
Pandas, Rhinos, the Asian Elephant, Orchids and Rafflesia are few of hundreds
of endangered species due to deforestation. Hilderman (2010) reckon that by the
first part of 21st century, about 50% of the remaining rainforest
and about 5% to 10% of all species on the planet will be lost due to the
continuation of deforestation.
Thus, deforestation is an
important issue to be discussed. It has adverse effects on each living beings’
life. Deforestation has become a huge concern in today’s life as there has been
a rise in the decline of forests. If major steps towards afforestation are not
taken, then even the great adaptability of human beings may not be enough to
cope up with the harsh climate of the future. Deforestation does have
solutions. It’s just that the people must step forward. The safe keeping of our
precious planet lies with each and every member of its human population.
