Which of the following is not a major cause of wetland loss?

• A. Barrier island degradation
• B. Habitat conservation
• C. Sea level rise
• D. Oil and gas development

Answer: (B)

Habitat conservation is focused on protecting and restoring natural environments, including wetlands, rather than contributing to their loss. Conservation efforts aim to maintain biodiversity, improve ecosystem health, and support wildlife habitats. By implementing protective measures, establishing conservation areas, and engaging in restoration projects, habitat conservation directly counters the threats to wetlands, helping to sustain these vital ecosystems rather than exacerbating their decline.

In contrast, barrier island degradation, sea level rise, and oil and gas development are activities that threaten wetland areas. They can lead to habitat destruction, increased salinity, and loss of ecosystem functions, which significantly contribute to wetland loss. Thus, habitat conservation stands out as the action that actively works against wetland loss, making it the correct answer in this context.
