Damming the Red Sea could solve the growing energy demands of millions of people in the Middle East and alleviate some of the region's tensions pertaining to oil supplies through hydroelectric power. Equally, such a massive engineering project may cause untold ecological harm and displace countless people from their homes.

The Blue Moon Fund recently awarded WWF a grant to ensure that construction of the Madeira dams in the Amazon River basin does not permanently harm the region's biodiversity, economic potential and local communities. Established in 2002, the Blue Moon Fund supports nonprofit organizations working to build a sustainable balance between humans and nature.
