Worked Solution & Example Answer:Examine the information above and answer the following questions - Leaving Cert Geography - Question A - 2012
Step 1
Which region had the highest CO₂(greenhouse gas) emissions and which region had the lowest CO₂(greenhouse gas) emissions in 2009?
Answer
The region with the highest CO₂ emissions in 2009 was Asia & Oceania, as indicated by the total emissions of 1,384 million metric tons. Conversely, the region with the lowest CO₂ emissions was Africa, with total emissions reported as 1,056 million metric tons.
Step 2
Calculate X, the percentage of greenhouse gas emissions generated by agriculture in Europe in 2010.
Answer
To calculate X, we first refer to the contributions of each sector. In 2009, agriculture contributed 7.0% to the total emissions in Europe. Therefore, X, representing the percentage of emissions from agriculture, is calculated as follows:
Thus, X equals 7.0%.
Step 3
Briefly explain one reason why Energy (excluding transport) was the sector which produced the highest percentage of greenhouse gas emissions in Europe in 2009.
Answer
Energy production, particularly from fossil fuels like coal and natural gas, is a major source of greenhouse gas emissions. The reliance on these energy sources for electricity generation and heating significantly contributes to CO₂ emissions, making the Energy sector the largest emitter. Furthermore, inefficiencies in energy use and the lack of renewable energy adoption at the time exacerbated the emissions from this sector.
Step 4
Step 5
State two ways the greenhouse effect impacts on agriculture.
Answer
-
Changes in Weather Patterns: The greenhouse effect can lead to altered weather patterns, causing unpredictable rainfall and temperature fluctuations, which can adversely affect crop yields and farming schedules.
-
Increased Carbon Dioxide Levels: While higher CO₂ can enhance photosynthesis, leading to greater plant growth, excessive levels can also lead to detrimental effects such as reduced nutritional value of crops and increased pest proliferation.
