Two women confronting the dangers of plastic pollution talk to Kim Chakanetsa. They’re sounding the alarm and working on innovative solutions: from an island clear-up that collected 750,000 empty plastic bottles to reducing microplastics in the air and waterways.

Estrela Matilde lives on the island of Príncipe off the coast of West Africa – where her work to reduce plastic pollution has helped increase the number of turtle nests by more than 40 percent to 2,500 over six years. Estrela is a Whitley Fund for Nature winner 2022.

Siobhan Anderson is a co-founder of a start-up called The Tyre Collective. They're working to find a solution to the plastic pollution caused by tyre wear. The waste from tyres as they degrade is the second largest microplastic pollutant in the environment – making up to 28% of primary microplastics in our oceans, as well as contributing to airborne pollution. Siobhan is from California in the United States and is now based in London.
