How you can be part of the Biggest Hour for Earth

Something special is about to happen at 8:30 p.m. local time this Saturday, March 23, as people in over 190 countries and territories unite to create the Biggest Hour for Earth — and you can be part of it!

Earth Hour, organized by WWF since 2007, is an annual moment that brings the world together, shines a spotlight on nature loss and the climate crisis, and inspires millions to act and advocate for urgent change. Last year, participants around the world gave more than 410,000 hours (!) for our shared home.

This year, we’re once again calling on individuals, communities and businesses to spend 60 minutes doing something — anything — positive for our planet on March 23.

Not sure how you’ll give your hour? Here are some ideas:

  • Raise your voice for marine wildlife. Join the call for Canada to take action on reducing underwater noise, which is harming species like narwhal and humpback whales. You can help turn down the volume on underwater noise pollution by sending an email to your MP telling Canada to finally release its long-waited Ocean Noise Strategy.

  • Dream up your action plan for creating wildlife habitat at home or in your community. Sign up for a free re:grow account to learn how you can help restore wildlife habitats by growing native plants. These plants provide resources like food and shelter that support birds, bees and other insects, small mammals, amphibians, reptiles and more.
  • Register for the WWF Climb for Nature. Every dollar you raise and every step you take brings us closer to a brighter future for nature. This year, you can participate in Toronto (April 20-21), Vancouver (May 26) or anywhere in Canada (April 20-June 9).

Whatever you decide to do, you can participate at the traditional hour of 8:30 p.m. your local time or anytime during the day of March 23.

Earth Hour may have started as a symbolic lights-off moment but, over time, it has grown into a movement that invites us to take action in diverse, meaningful ways — and the urgency has only increased.

“Every year, we’re witnessing wildfires, floods and other devastating impacts of climate change and biodiversity loss,” reflects Megan Leslie, WWF-Canada’s president and CEO. “It can feel overwhelming, but we still have time to reverse the path we’re on. Earth Hour is a yearly reminder that, across our society here in Canada and across the world’s borders, we can work together to make a difference for our shared home. Every person and every hour count.”

So, can we count you in? Join us this Saturday and help create the Biggest Hour for Earth!
