Around 40 volunteers gather on Guacalillo Beach, on the Pacific coast of Costa Rica, to clean its shores. "Costa Rica sells itself as a green country, but the reality is that there is a lack of awareness and education” says Montserrat Courrau, a participant in the cleanup day. In 2021, the country generated over 1.6 million tonnes of municipal waste according to the Organisation For Economic Co-operation And Development (OECD).
