  • Blue Carbon: Why restoring coastal wetlands can help combat climate change

    05/10/2016 Duración: 50min

    While efforts move forward to figure out ways to reduce global greenhouse gases and carbon emissions, efforts are also moving forward to figure out ways to sequester carbon.

Learn about how agencies and organizations are working to advance restoration of wetlands through local and national efforts.
