How does deforestation contribute to the enhanced greenhouse effect?
Reduces the number of trees that absorb carbon dioxide through photosynthesis
Stored carbon in trees is released back into the atmosphere as carbon dioxide
Clearing of trees exposes the soil beneath to sunlight, which increases soil temperature and the rate of carbon oxidation
The fallen trees will decrease albedo and cause more reflection of incoming solar radiation
How does agriculture contribute to the enhanced greenhouse effect?
Nitrogen in chemical fertilisers converts to nitrous oxide
Burning of fossil fuels to produce energy for farm machinery
Irrigation flushes the carbon out of the soil and into the atmosphere
Livestock rearing and natural decomposition processes release methane
How does industries contribute to the enhanced greenhouse effect?
Fossil fuels are burned to generate energy to run the machinery and other factory processes.
Machineries emit waste heat when in use
Industries do not contribute to the enhanced greenhouse effect
Workers at the industries go on strike
How does urbanisation contribute to the enhanced greenhouse effect?
Fossil fuels are burned to power the high concentration of vehicles
Households consume energy for heating, cooling and lighting
Residents have rooftop gardening to tap on the natural sunlight
Roads and concrete reflect more incoming solar radiation due to darker surface
