The draining and alteration of wetlands for agriculture and urban development is the most problematic human activity for wetlands around the world. Wetlands play important roles in flood control, water filtration, wildlife habitat, and carbon storage, but they have been drained, filled, and developed for human use, which has resulted in their loss and degradation. Eutrophication and boat traffic can also cause harm to wetlands, but the drainage and development of wetlands is the root cause of their decline. The alteration of ocean current circulation is not a direct human activity affecting wetlands, but it can have an indirect impact on them.
