Around 8m tonnes of plastic end up in the ocean each year. How can we clean up our seas?
1) Develop green alternatives
Just 14-16 per cent of plastic packaging is recycled each year worldwide. But there is a growing focus on the development of ‘bioplastics’.
Existing projects include biodegradable water bottles made from algae, and a range of packaging that takes just six months to break down in garden compost.
2) Invest in clean-up technology
Scientists and inventors are working on ways to clean up the plastic that is already in the sea. A trawling net by The Ocean Cleanup project is designed to scoop up microplastics and can be attached to existing vessels. Other designs use ocean currents to collect waste via floating barriers and ‘sea bins’.
