Good afternoon!

From scientific discoveries to activist wins, here are the latest news stories showcasing the people taking on climate change and nature loss.

🦪 Oysters: an ancient climate solution

Oysters are one of the most sustainable species on earth. With no fertilisers or pesticides required for them to grow, they could play a critical role in feeding the planet without harming it further. In fact, rather than putting pressure on ecosystems, they support them, through filtering water pollution, promoting biodiversity, and even storing carbon. Plus, oysters’ ability to stop erosion and boost shorelines’ resilience to storms mean they act as a natural sea wall.

🐘 Progress on global biodiversity

At global biodiversity talks in Rome – a continuation of last year’s COP16 in Cali, Colombia – countries agreed on a strategy to mobilise $200bn a year to stave off nature loss. Delegates also agreed on a mechanism for monitoring countries’ progress towards conserving 30% of the world’s land and sea. 

“The common good – the environment, the protection of life and the capacity to come together for something bigger than each national interest – is possible.”

🏡 How green roofs make for better cities

Basel, Switzerland has found a way to weave natural and urban landscapes through cultivating green rooftops. These green spaces are deliberately made into a home for native plants, naturally restoring local wildlife. The roofs keep the city cooler during heatwaves and store excess rainwater, and the plants can exist alongside solar panels.
