Restoring and protecting nature is one of the greatest strategies for tackling climate change, but not just for the obvious reason that it sucks carbon out the air. Forests, wetlands, and other ecosystems act as buffers against extreme weather, protecting houses, crops, water supplies and vital infrastructure. The strategy of using nature as a defence against climate impacts is called called ecosystem-based adaptation (EbA) – in essence, look after nature and it will look after you.
