Welcome to another episode of the EarthX Conference series!

When you think of ocean conservation, coral reefs likely come to mind. But what if the real unsung hero of the sea is something far less glamorous—and far more vital? Filmmaker Adam Hussain brings us into the underwater world of kelp forests in his upcoming documentary Seaforestation. These underwater ecosystems cover more area than coral reefs, support an astonishing range of marine life, and play a quiet but powerful role in fighting climate change.

Adam shares surprising facts—like how kelp forests could be worth more than the Great Barrier Reef in economic value—and tells stories from the field, including sea lions hopping aboard boats and witnessing the last 5% of Tasmania’s once-vast giant kelp forests. If you've ever dismissed seaweed as just ocean salad, this episode might just change your mind.

Highlights:

  • Why kelp is critical to coastal ecosystems and climate stability?
  • What’s threatening these forests—and it’s not just one thing?
  • How scientists are using “assisted adaptation” to help kelp survive warming oceans? 

What YOU Can Do

  • Most people don’t even know kelp forests exist, let alone how important they are. Just talking about what you learned in this episode can spark awareness and curiosity.
  • Companies that farm seaweed responsibly (rather than harvesting it from the wild) are helping create demand for sustainable ocean industries. Look for packaging and food products made from farmed seaweed.
  • Ocean warming is one of the biggest threats to kelp. Cutting back on emissions—from energy use to transportation to food choices—can make a difference at scale.
