New findings suggest animal-mediated plant reproduction might have originated in the ocean.
We cannot afford to ignore kelp – these vibrant underwater forests have sustained people and ecosystems for centuries, and continue to do so today.
When we stopped whaling, the whales recovered. But our vital kelp forests won’t return without our help

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
A solution for managing the growing populations of long-spined sea urchins may not be clear at the moment, but there is a path forward.
Our ocean forests of seaweed are enormous. But these quick-growing, life-supporting forests are already vanishing.
Seaweed was thought to be a vital tool in the fight to slow climate change. But it turns out seaweed ecosystems may be a natural source of carbon dioxide – and not a sink.
The indirect losses from one heatwave in Western Australia caused A$4.14 billion per year worth of damage.

Plus, new discoveries about early humans in Tanzania’s Olduvai Gorge. Listen to episode 5 of The Conversation Weekly podcast.
An array of leaves showing the diversity of kelp in underwater Arctic forests.
With global warming, underwater Arctic kelp forests are proliferating, and might be a potential resource.
Recent marine heatwaves have devastated crucial coastal habitats, including kelp forests, seagrass meadows and coral reefs.
Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern Canada are most at risk.
Southern bull kelp can drift huge distances before washing ashore.
A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.
Kelp forests in South Africa are thriving but the marine life relying on it aren’t.
Climate change affects kelp forests all over the world differently. In southern Africa, they seem to be thriving which should be good news. The marine life relying on kelp, are however struggling.
Kelps form Australia’s neglected Great Southern Reef.
Cool-water kelp forests are being eaten by tropical species moving south on warming waters.
The 2011 heatwave hit kelp forests hard along a long stretch of WA coast.
A 10-week surge in ocean temperatures off the Western Australian coast has killed off large patches of kelp forest, the “biological engine” of Australia’s southern reefs.
