New research shows that chemicals leached from ocean plastic impair the growth and oxygen production of the planet's most abundant photosynthesiser - endangering marine ecosystems and the climate.
Biodegradable bags still strong enough to carry shopping after three years in the ground show that 'biodegradability' isn't all it's cracked up to be.
Asian countries have become a dumping ground for the plastic waste from wealthy countries.
Academics from different disciplines come Head to Head in this series to tackle topical debates.
Cleaning up plastic pollution in the ocean is good – and long overdue. But where will the waste go? Recycling isn't always an option. Bacteria and enzymes could process it, raising new questions.
Autopsies of 1,000 turtles washed up on Australian beaches paint a grim picture of the impact of plastic debris. Even a single piece can be deadly, and on average 14 pieces equals a 50% fatality rate.
Tech fixes to environmental problems are guaranteed to grab attention, but real change for the planet requires community organising.
Ocean plastic has made a big splash, but there may be even more microplastic on land. The problem is that we have no idea exactly how much is in Australian soil, where it is, and what it's doing.
The technology underlying Bitcoin is starting to spread its wings.
Cleaning up the oceans will require much better waste management in poorer countries.
Plastics and microplastics in the marine environment are one of the great cause célèbre of our era. Here's what we know and don't know.
Summer may have come to an official end, but the plastics from your bathers might still be at the beach!
Drink containers end up in the ocean at a truly alarming rate. Simply paying people a small amount to return them cuts that rate by nearly half.
Millions of tonnes of plastic garbage winds up in our oceans each year. Voluntary pledges haven't worked. It's time for Canada to advocate for an international plastics treaty.
Coral reefs in the Asia-Pacific have been deluged with an estimated 11.1 billion pieces of plastic waste, increasing the risk of coral disease more than 20-fold.
Plastics pose a major threat to seabirds and other animals, and most don't ever break down - they just break up. Every piece of petrochemical-derived plastic ever made still exists on the planet.
Waste plastic affects marine life significantly but better education and recyclable plastics could go a long way in resolving this issue.
