What are the effects of wetlands?

Importance of Wetlands

Wetlands include marshes, swamps, bogs, and similar areas that are periodically saturated with or covered by water. They provide food and habitat for a diverse array of plants and animals, act as buffers to flooding and erosion, and serve as key links in the global water cycle.

How do wetlands reduce global warming?

Wetlands continuously remove and store atmospheric carbon. Plants take it out of the atmosphere and convert it into plant tissue, and ultimately into soil when they die and decompose.
