Awareness is increasing about foods like lab-grown meat, insects and seaweed. These foods may help address environmental challenges, but it's important to be aware of both the costs and benefits.

Small wounds can usually heal by themselves, but larger wounds can be a problem. With a little help from a seaweed we can help the body regenerate new blood vessels.
Feeding pigs seaweed could make them, us and the planet healthier without contributing to antibiotic resistance in bacteria.
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.
Climate change will affect the nutrition of seaweeds eaten by billions of people around the world.
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.
The most dangerous element from discarded plastic waste is microplastics.
Indonesia is the world's largest producer of the seaweed that offers a solution for the global plastic crisis.
The ocean is getting warmer and more acidic but changing our diet could help us cope.
Tonight on the ABC's Catalyst, scientist Tim Flannery asks if seaweed can save the world. It's a bold claim for algae, but seaweed could play a key role in keeping climate change in check.
Giant kelp can grow up to 60cm a day, given the right conditions.
In an extract from his new book, Tim Flannery explains how giant kelp farms could suck carbon dioxide from the air and store it in the ocean's depths, while encouraging species like fish and oysters.
Four organisms that show nature isn't so easily categorised.
Kelps form Australia’s neglected Great Southern Reef.
Cool-water kelp forests are being eaten by tropical species moving south on warming waters.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.
T. Wernberg 2002
The Great Southern Reef covers 71,000 square km and contributes more than A$10 billion to Australia's economy each year.
