Earth Hour 2021: A message from United Nations Secretary-General Antonio Guterres

Nature makes our lives better and allows us to thrive by giving us food, clean air, and freshwater. But we are pushing the planet to the limit, increasing our vulnerability to pandemics, accelerating climate change and putting livelihoods at risk.

2021 is the year to change course, starting with #EarthHour by putting the spotlight on our planet and inspiring action for a brighter future for nature and people.

"In this make-or-break year, let your actions and voices send a clear message to leaders everywhere. Now is the time to be bold and ambitious, and show the world we are determined to protect the one home we all share."
