We always hear about the "three Rs" — reduce, reuse, and recycle — of sustainable waste management. But when it comes to single-use plastics, climate activist Hannah Testa likes to add two more: refuse and raise awareness. What's more, she says it's crucial to connect the problem with climate by showing the damage that single-use plastic waste is doing to the oceans, the world's biggest carbon sink and whose health is a good temperature check on the entire planet.
Testa spoke during the second of a two-part Sustainability Leaders Summit livestream conversation sponsored by Suntory.
