Our world needs transformational change. People and the planet are only as healthy as the ecosystems we all depend on. Bringing degraded ecosystems back to life – for example by planting trees, cleaning up riverbanks, or simply giving nature space to recover – increases their benefits to society and wildlife. Without reviving ecosystems, we cannot achieve the Sustainable Development Goals or the Paris Climate Agreement.
Earth Day recognises the Earth and its ecosystems as humanity's common home and the need to protect her to enhance people’s livelihoods, counteract climate change, and stop the collapse of biodiversity. The theme for 2021 is Restore our Earth.
