How does urbanization contribute to climate change?

• A. It decreases population density
• B. It leads to increased greenhouse gas emissions
• C. It improves energy efficiency
• D. It reduces land use for agriculture

Answer: (B)

Urbanization contributes to climate change primarily by leading to increased greenhouse gas emissions. As more people move to urban areas, the demand for energy, transportation, and infrastructure grows significantly. Urban areas often rely on fossil fuels for energy production, which releases carbon dioxide and other greenhouse gases into the atmosphere. Additionally, urbanization typically involves the construction of buildings, roads, and other infrastructure, which can also result in emissions from materials like concrete and steel. Furthermore, urban sprawl can increase reliance on vehicles for transportation, further elevating emissions due to greater distances traveled and congestion. Overall, urbanization intensifies human activities that emit greenhouse gases, making it a key factor in the broader challenge of climate change. In contrast, the other choices do not accurately reflect how urbanization interacts with climate change dynamics. For example, decreasing population density does not correlate with urbanization; it often increases density. Similarly, while urban areas might implement energy-efficient technologies, the overall trend of increased energy demand tends to overshadow these improvements in efficiency. Lastly, urbanization often encroaches on agricultural land, rather than reducing its use, which can lead to further environmental pressures.
