Question 3.1, Human Activities Responsible for Changes in the following:
a) Carbon dioxide
This is mostly caused by human activities such as electricity consumption, combustion of
fossil fuel such as coal and oil; motor vehicle exhaust fumes from transportation activities;
industrial activities such as iron and steel smelting and deforestation.
b) Atmospheric water vapor
Anthropogenic activities such which produce methane gases to the atmosphere also affects
the water vapor, as the methane gas produces a small amount of water vapor as a result of
undergoing chemical destruction in the stratosphere. Such human activities include agriculture
especially rice fields and livestock and extraction and combustion of fossil fuel (Solomon. et al.,
c) CH4
CH4 or methane is mostly caused by human activities such as agriculture especially the paddy
rice fields and livestock, fossil fuel extraction and decomposition of organic wastes in landfills.
Most chlorofluorocarbons have increased due to human industrial activities tailored to the
production of different products and in ...
