Human Impact on Cycles
We, as humans, have an effect on everyone and everything around us including the
four main cycles of the Earth; water cycle, nitrogen cycle, carbon cycle, and the phosphorus
cycle.
The water cycle is
the circulation of the earth's water, in which water evaporates from
the surface into the atmosphere, where it condenses and returns back to the Earth’s surface
as rain or snow. Water is an essential necessity in every living, biotic thing. Humans have an
impact of the water cycle is many different ways, some being beneficial and some being
harmful to our environment. One beneficial way that humans impact the water cycle is the use
of hydroelectric energy. Hydroelectric energy is the conversion of flowing water into energy.
This process helps with less pollution and it also always evaporation to be easily by gathering
large bodies of water together. However a negative impact that humans may have on the
water cycle is deforestation, the removal of trees, and it is impacting our water cycle because
it’s causing major climate change resulting in less transpiration from the trees, which is an
important part of our water cycle.
The nitrogen cycle is a series of processes by which nitrogen and its compounds are
circulated within the environment and within living organisms, including nitrogen fixation and
decomposition. Nitrogen is one of the primary nutrients critical for the survival of all living
organisms. Although nitrogen is abundant in the atmosphere, it can’t be accessible through
specific forms to specific organisms. Many human activities have a significant impact on the
nitrogen cycle, burning fossil fuels, application of nitrogen­based fertilizers, and other activities
can dramatically increase the amount of nitrogen in an ecosystem, large changes in the
availability of nitrogen can lead to severe alterations of the nitrogen cycle in ecosystems,
i
ncreases in nitrogen can often lead to hypoxia (low oxygen), decrease in biodiversity,
changes in food­web, and many other harms to the environment.
The carbon cycle is the process by which carbon compounds are circulated throughout
the environment, such as carbon dioxide into living tissue by photosynthesis and its return to
the atmosphere through respiration, the decay of dead organisms, and the burning of fossil
fuels. Carbon is an essential part of the environment. Humans impact the…
