Question 9C
Examine the environmental impacts of burning fossil fuels.
Worked Solution & Example Answer:Examine the environmental impacts of burning fossil fuels. - Leaving Cert Geography - Question 9C - 2020
Step 1
Identify Environmental Impacts
Answer
-
Air Pollution: The combustion of fossil fuels releases a variety of pollutants, including carbon dioxide (CO₂), nitrogen oxides (NOx), sulfur dioxide (SO₂), and particulate matter. These pollutants contribute to respiratory diseases, acid rain, and climate change.
-
Greenhouse Gas Emissions: Burning fossil fuels is the largest source of CO₂ emissions, a major greenhouse gas. This leads to global warming and climate change, impacting weather patterns, sea levels, and ecosystems.
-
Water Pollution: Oil spills and runoff from coal mining can contaminate water bodies. Chemicals from burning fossil fuels can leach into water supplies, harming aquatic life and human health.
-
Land Degradation: Fossil fuel extraction processes, such as mining and drilling, can lead to habitat destruction, soil erosion, and deforestation, impacting biodiversity and land usability.
Step 2
Examine the Impacts
Answer
The examination of these impacts can be organized into several key points:
-
Health Consequences: The air pollutants released from burning fossil fuels pose serious health risks. Prolonged exposure can lead to chronic respiratory diseases, cardiovascular issues, and increased mortality rates.
-
Economic Costs: The economic implications of fossil fuel pollution can be severe, including healthcare costs, loss of workforce productivity due to illness, and damage to infrastructure from climate change effects.
-
Climate Change Feedback Loops: Increased CO₂ levels lead to higher global temperatures, which in turn can cause phenomena such as ice melting and increased frequency of extreme weather events, creating further environmental and societal challenges.
-
Biodiversity Loss: Pollution and habitat destruction from fossil fuel extraction are significant contributors to loss of species and biodiversity. This disrupts ecosystems and weakens their resilience.
-
Energy Transition Challenges: The reliance on fossil fuels complicates efforts to transition to renewable energy sources, as it involves significant infrastructure changes and economic detachment.
-
Global Inequities: The adverse effects of fossil fuel pollution are often felt more acutely in lower-income communities and developing nations, leading to greater environmental injustices and inequities.
-
Policy and Regulation: Effective governance and regulations are needed to mitigate these impacts. Policies aimed at reducing emissions and promoting clean energy are crucial for sustainability.
-
Environmental Restoration: Addressing the impacts of fossil fuel use also involves restoration efforts for polluted and degraded environments, which can be costly and complex.
-
Public Awareness: Educating the public about the impacts of fossil fuel consumption can drive demand for cleaner alternatives and more sustainable practices.
-
Future Projections: Failure to address these impacts could lead to severe long-term consequences for the planet, including uninhabitable areas due to climate change and severe resource shortages.
