Question B
Examine the environmental impact of burning fossil fuels.
Worked Solution & Example Answer:Examine the environmental impact of burning fossil fuels. - Leaving Cert Geography - Question B - 2013
Step 1
Identify Environmental Impacts
Answer
The burning of fossil fuels primarily contributes to several key environmental impacts:
-
Air Pollution: Emission of pollutants such as carbon dioxide (CO₂), sulfur dioxide (SO₂), nitrogen oxides (NOx), and particulate matter leads to poor air quality, which can cause respiratory illness and cardiovascular diseases.
-
Greenhouse Gas Emissions: Fossil fuels are significant sources of greenhouse gases, especially CO₂, which contributes to global warming and climate change by enhancing the greenhouse effect.
-
Acid Rain: Sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere to form acidic compounds, leading to acid rain that can harm ecosystems, soil, and water bodies.
-
Ozone Depletion: Emissions from burning fossil fuels contribute to the depletion of the ozone layer, impacting sunlight protection and increase UV radiation reaching the Earth’s surface.
-
Climate Change: The increase in greenhouse gases contributes to rising global temperatures, resulting in more extreme weather patterns, melting ice caps, and rising sea levels.
-
Biodiversity Loss: Habitat degradation due to fossil fuel extraction and emissions can lead to loss of biodiversity, endangering various species and disrupting ecosystems.
-
Water Pollution: Runoff from fossil fuel combustion can contaminate water sources with heavy metals and other harmful substances, affecting aquatic life and human health.
Step 2
Examine the Environmental Impact of Burning Fossil Fuels
Answer
The examination of the environmental impacts of burning fossil fuels can be organized into various sections, detailing deeper effects:
Climate Change and Global Warming
Burning fossil fuels releases vast amounts of CO₂, which is a major contributor to climate change. The Intergovernmental Panel on Climate Change (IPCC) highlights that to limit global warming, substantial reductions in CO₂ emissions are necessary.
Economic Costs
The negative environmental impacts lead to significant economic costs related to health care, lost productivity, and damage control in affected areas. For instance, respiratory diseases linked to air pollution lead to a burden on health systems.
Regulatory Measures
Governments worldwide are implementing stricter emissions regulations and promoting renewable energy solutions as a response to the adverse effects of fossil fuel combustion, aiming to reduce overall environmental impact.
Sustainable Alternatives
The shift towards sustainable energy sources like wind, solar, and hydroelectric systems is crucial for mitigating the adverse impacts of fossil fuels. Transitioning involves both technological advancements and policy reforms to support green energy initiatives.
Public Awareness and Advocacy
Raising public awareness about the detrimental effects of fossil fuels is vital in fostering a culture of sustainability. Advocacy for cleaner energy options pressures industries to adopt more environmentally friendly practices.
