Wetlands and Mangroves: Ecosystem Services

This video by Mr. V covers the human impacts on wetlands and mangroves, highlighting their environmental services such as purification, flood protection, and habitat provision. It discusses anthropogenic threats like development and dam construction, using the Three Gorges Dam as an example. The video also focuses on mangroves, their role as nurseries for fish, and the challenges they face from erosion and development.
