Question 1
Examine the environmental impacts of burning fossil fuels.
Worked Solution & Example Answer:Examine the environmental impacts of burning fossil fuels. - Leaving Cert Geography - Question 1 - 2020
Step 1
Identify Environmental Impacts
Answer
The burning of fossil fuels has several environmental impacts. Two significant impacts include:
-
Greenhouse Gas Emissions: Burning fossil fuels releases carbon dioxide (CO₂) and other greenhouse gases into the atmosphere. This accumulation contributes to global warming and climate change.
-
Air Pollution: Combustion of fossil fuels also emits harmful pollutants, including sulfur dioxide (SO₂), nitrogen oxides (NOx), and particulate matter, which can lead to respiratory problems and adverse health effects in humans.
Step 2
Examination of Greenhouse Gas Emissions
Answer
The increase in CO₂ levels from fossil fuel combustion enhances the greenhouse effect. This potentially leads to climate changes, including rising sea levels and extreme weather patterns. These changes disrupt natural ecosystems and can lead to species extinction, as many plants and animals cannot adapt quickly enough to the changing climate.
Step 3
Examination of Air Pollution
Answer
Air pollutants from burning fossil fuels can cause smog and acid rain, which harm both human health and the environment. For instance, nitrogen oxides contribute to the formation of ground-level ozone, which is a key ingredient in smog. This not only affects air quality but can also damage crops and other vegetation, leading to reduced agricultural productivity.
