Question

why wetland are important

Answer 1

Wetlands prevent flooding by holding water much like a sponge.And wetlands help keep river levels normal and filter and purify the surface water. Wetlands also release vegetative matter into rivers, which helps feed fish in the rivers. Wetlands help to counter balance the human effect on rivers by rejuvenating them and surrounding ecosystems. Unlike most other habitats, wetlands directly improve other ecosystems. Wetlands also clean the water by filtering out sedimentation, decomposing vegetative matter and converting chemicals into useable form. The ability of wetlands to recycle nutrients makes them critical in the overall functioning of earth. No other ecosystem is as productive, nor as unique in this conversion process. In some places artificial wetlands were developed solely for the purpose of water purification.
