8. The Sundarbans (India/Bangladesh)
The Sundarbans, the world’s largest mangrove forest, straddles the coasts of India and Bangladesh. Rising sea levels and more frequent, intense cyclones threaten this unique ecosystem, imperiling endangered species like the Bengal tiger. Saltwater intrusion and erosion also jeopardize the livelihoods of millions living nearby. Similar to other coastal wetlands, such as the Everglades, the Sundarbans are on the frontlines of climate change—demonstrating how environmental shifts ripple through both nature and human communities.
