Kelp forests, mangroves, seagrass meadows, and coral reefs are vital blue ecosystems that sustain our planet.

Yet, they are severely threatened by climate change, biodiversity loss, pollution, and waste.

Here's why their protection matters: www.unep.org/interactives...

Text overlay reads: “Seagrass meadows store carbon up to 35 times faster than tropical rainforests, and are an important habitat for dugong and seahorses.

When we conserve an area, it's not enough to draw lines on a map and walk away.

We need clear goals – and long-term commitment – to ensure these places thrive into the future.

The Underfunded, Underestimated, Yet Critical Side of Conservation

Designating protected areas is only the first step. Stewarding the areas and ensuring they meet their goals is critical to long-term success.
