How do human activities lead to the enhanced greenhouse effect?
One anthropogenic factor is
deforestation
and the
associated increase in atmospheric carbon dioxide
Carbon in soil
accumulates through the
decay of organic matter
Carbon dioxide
is also
emitted
during the
process of deforestation and land clearance
Deforestation
exposes soil to sunlight
, causing an
increase of soil temperature
and
rate of carbon oxidation
in the soil
With deforestation, there are
fewer trees
to
absorb carbon dioxide
causing an
increase in carbon dioxide levels
in the
atmosphere
Carbon oxidation
is a process in which
carbon in the soil
reacts with
oxygen
in the atmosphere to
produce carbon dioxide
Forests absorb
billions of tonnes of carbon dioxide
every year via
photosynthesis
, thus
taking in a significant amount of global greenhouse gas emissions
Deforestation
increases the rate
at which
carbon dioxide
is
released from the soil
into the
atmosphere
Deforestation is the
loss of forests
due to the
removal or clearance of trees in forested areas
Another anthropogenic factor is
changing land use
and associated
increase in greenhouse gases
The use of
inorganic fertilisers increases
the
amount of nitrous oxide
in soil
Nitrous oxide is
released when soil
is
ploughed
or when
rain flows through the soil
Tractors run on
fossil fuels
which
release carbon dioxide
Cattle farming contributes to
greenhouse gas emissions
due to the
cattle releasing methane
as a
waste gas
Agriculture is the
practice of cultivating land
,
producing crops
, and
raising livestock
which is also the
third-highest contributor of greenhouse gases
Industries
Secondary industries
involve the
burning of fossil fuels
that result in
greenhouse gas emissions
Greenhouse gases
are also
released
as by
products when goods produced
It is the
production of goods
and
services
within the country
Some
processes or products
result in
greater emissions than others
Urbanisation
Large amounts of fossil fuels
are
burnt
to
provide energy
for
household activities
in urban areas
The
high concentration of transport vehicles
also contributes to the
amount of greenhouse gases emitted
in these areas
It is the process by which an
increasing number of people
living in
urban areas
Constructing infrastructure
and
producing construction materials
also
release greenhouse gases
into the atmosphere
The enhanced greenhouse effect is an
increase
in the
concentration of greenhouse gases
in the atmosphere, leading to a
rise in global temperatures
