Earth Hour: 8:30 PM
March 28th, 2020

Earth Hour had its beginning in Sydney, Australia in 2007.  Since then it has quickly become a global environmental movement uniting people from all nations in an urgent call for action on climate change.  This year hundreds of millions of people around the world will turn 'lights out' for one hour to show their commitment to  helping something we all have in common- the planet.

For young people, Earth Hour can be a meaningful reminder that important environmental issues don't have to overwhelm us and that there are small things we can do every day to make a difference.  The days leading up to March 28 are an excellent time for students and teachers to explore climate change in the classroom and bring meaning to participation in Earth Hour.

Why Participate in Earth Hour?

Climate change is altering the planet. Severe environmental, economic and social consequences are becoming more and more evident as global temperatures increase. This year, WWF Canada is placing its Earth Hour focus on wildlife loss in Canada and around the world.

  • Rising temperatures due to global warming threaten to increase flooding and droughts putting millions of homes at risk and endangering as many as 30 percent of animal species according to the United Nations Intergovernmental Panel on Climate Change.
  • In Canada, populations of more than one-half of monitored species have already declined by 83 per cent on average since 1970. Globally, we’re on track to lose 67 per cent of wildlife populations by 2020. (WWF 2020)
  • Globally the five hottest years on record have all occurred in the last 5 years! (NASA 2019) 
  • Currently there are more than 100 million people living within three feet of sea level
  • Two-thirds of the world's polar bears could be lost within 50 years as a result of retreating sea ice, according to the U.S. Geological Survey.
  • The IPCC estimates 3 billion or more people will be at risk of water shortage due to climate change in the decades ahead.
  • Per capita, Canada is among the top C02 emitting countries in the world
  • Research conducted by the NRDC shows that if present trends continue, the total cost of global warming over the next century will be measured in the trillions of dollars.

Climate change is increasingly affecting human health, species distribution and the ability of the planet to provide.   How we deal with climate change is a crucial discussion that teachers and students should be actively engaged in.
