Which human activity has a direct impact on wetland degradation?

• A. Conservation efforts
• B. Reforestation
• C. Oil and gas development
• D. Wildlife protection

Answer: (C)

The human activity that has a direct impact on wetland degradation is oil and gas development. This activity often involves the extraction of resources from beneath the wetland environment, which can lead to significant ecological disruption. The construction of infrastructure, such as pipelines and access roads, can alter the natural flow of water, result in habitat loss, and introduce pollutants into the ecosystem.

Wetlands play a crucial role in filtering water, providing habitat for various species, and acting as a buffer against flooding. Oil and gas development can compromise these functions, leading to a decline in water quality and biodiversity. Additionally, the physical footprint of extraction activities contributes to habitat fragmentation, making it difficult for wildlife to thrive.

In contrast, conservation efforts, reforestation, and wildlife protection are focused on preserving and restoring natural environments, which can contribute positively to wetland ecosystems rather than degrading them.
