From the show
As the UN Ocean Conference kicks off in Nice, we're focusing on seagrass meadows: vital climate allies that are among the least protected ecosystems on Earth. They store more CO2 per hectare than land forests and are home to vulnerable species such as seahorses. Yet nearly 30 percent of these underwater plants have already disappeared worldwide due to pollution, rising temperatures and harmful fishing techniques.
In Arcachon Bay in southwestern France, locals and scientists have joined forces to revive Europe's largest seagrass meadow and protect its biodiversity.
In this episode of Down to Earth, we dive into a little-known but crucial climate and biodiversity battle.
