Earth Hour is back for its tenth year in Sydney, this time we're switching off for the places we love
Founded in Sydney and now celebrated in more than 160 countries, Earth Hour is a global event that hopes to shine a light on issues affecting the environment. Lights are switched off in homes and businesses around the world to make a statement and to acknowledge climate change. This year's focus is on protecting the places we love and the outdoor lifestyle in Australia; it only takes a small rise in global temperatures to cause extreme weather patterns, which already threatens the things we love from coral reefs to the key ingredients used in beer. Register your event on the Earth Hour website.
