Introduction
This project review concerns four key concepts from the course, their interrelationship
and how they impact human life. The four chosen concepts are deforestation, ecosystem,
agriculture and the atmosphere.
Atmosphere is a layer of gases surrounding a planet that is suspended by the gravity. It is
composed of four layers, troposphere being the lowest layer expanding from the Earth’s surface
to about 30 miles high. Most of Earth’s weather occur in the troposphere. Stratosphere is just
above the troposphere and this is where we find ozone layer that blocks ultraviolet rays. After
stratosphere there is mesosphere, thermosphere and then ionosphere. The Earth’s atmosphere
also houses various types of lighting, clouds and auroras. An ecosystem is a topographic part of
the earth where animals, plants, landscape and weather combine together to form life. It is
composed of living and non-living things which directly or indirectly depend on each other.
Agriculture is a process of food production, fuel, feed, fiber and some other products by routine
raising of animals and plants. Human beings have been obtaining food from agriculture since the
early ages. Deforestation is a lasting cutting of trees in a forest so as to clear the land and make it
available to be utilized in agriculture or for urban development. About 18 million acres of forest
is cleared annually to avail land for other uses (Yohannes, 2016).
Interrelationship between Deforestation, Ecosystem, Agriculture and Atmosphere, and
their impacts on Human Life.
There have been worldwide campaigns against mass destruction of trees so as to reduce the
rate of climate change and preserve wildlife. Trees are very important features in the ecosystem
because of various reasons which include absorption of carbon dioxide which we exhale and
trapping of gases from the greenhouses due to human activities. Deforestation interferes with
ecosystem and lead to devastating outcomes on global level. Since various species eat specific
foods and reside in different types of habitats, varying set of vegetation can enhance a wider
variety of animals to live in an area (Alina, 2018).
When deforestation is carried out to create space for large plantations for growing a specific
crop such as sugarcane, the diversity of wildlife plummets due to displacement of species. In as
much as deforestation affects forests it also has an effect on immediate surroundings and
atmosphere which spreads all through to the biosphere, ecosystems and all its constituents.
