What role do wetlands play in environmental management?

Wetlands play a crucial role in environmental management, particularly in the context of water management and flood control. They act as natural sponges, absorbing excess rainfall and stormwater runoff, which helps to mitigate flooding in surrounding areas. By retaining water, wetlands can gradually release it, maintaining stream flows during dry periods and enhancing overall water quality. This absorption capacity is especially important in regions prone to heavy rains or sudden storms, as it reduces the likelihood of flash flooding and minimizes erosion.

In contrast, while wetlands can provide some agricultural benefits or serve urban development needs, these aspects do not define their primary environmental purpose. Their primary ecological function is to regulate and manage water systems, which includes flood mitigation. Thus, option B accurately reflects the essential and beneficial role that wetlands play in environmental management.
