Environmental Impacts of Deforestation
Jamie Johnson
There are many ecological challenges that face humanity today. However, I will discuss
three of these challenges: The disruption of the carbon cycle, the disruption of the water cycle,
and the reduction of species diversity. I will also discuss how deforestation contributes to all of
these challenges.
The first ecological challenge is the disruption of the carbon cycle. The carbon cycle is
the flow of carbon between each of these places. Carbon repeatedly flows in and out of the
atmosphere and also living things. As plants photosynthesize, they soak up carbon dioxide from
the atmosphere. When plants die, the carbon goes into the soil, and microbes can release the
carbon back into the atmosphere through decomposition. Forests act as carbon sinks by
absorbing carbon dioxide while also releasing oxygen into the atmosphere. Carbon sinks absorb
large amounts of carbon dioxide from the atmosphere. The carbon sink is dramatically reduced
as forests are cleared. This is because trees absorb the carbon dioxide and when they are cut
down it that carbon dioxide is not absorbed and then there is an abundance of it. This then adds
to the global greenhouse gas production and also adds to global warming. Another way humans
have disrupted this cycle is by burning fossil fuels. Fossil fuel is a fuel, such as gas, coal, or oil,
that were formed underground from plant and animal remains. This reason is the second major
cause of deforestation.
The next ecological challenge is the disruption of the water cycle. The water cycle is the
process by which water circulates between the earth's oceans, atmosphere, and land, involving
precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by
evaporation and transpiration. There are a number of human activities that can affect the water

cycle such as damming rivers for hydroelectricity, rising water for farming, and deforestation. I
want to focus on deforestation and how that impacts the water cycle. Rain forests store extensive
quantities of water, and when those trees are cut down, the water they store is lost. As trees and
plants are responsible for withdrawing groundwater from the soil and returning it to the
atmosphere, deforestation results in the water not being able to be released back into the
atmosphere, affecting the balance of the water cycle. This results in lush rainforests turning into
barren deserts (Desertification), leading to dry climates, which affects living conditions. Trees,
especially forests in a tropical climate, release water vapor in the atmosphere. The water vapor in
the atmosphere regulates global climate. This water vapor is considered the world’s leading
contributor in greenhouse gases.
The last ecological challenge is the decline in species diversity. Species diversity is the
number of species and abundance of each species that live in a particular location. The main
cause of the loss of species can be attributed to the influence of human beings on the world’s
ecosystem, in fact humans have greatly changed the environment, and have altered the region,
exploiting the species directly. The threats to species can be summarized in the following main
points:
Alteration and loss of the habitats: the modification of the natural areas determines
not only the loss of the vegetable species, but also a reduction in the animal species
associated with them.
Pollution: human activity influences the natural environment producing negative,
direct or indirect, effects that changes the flow of energy, the chemical and physical
laws of the environment and abundance of the species;
