This Saturday homes and businesses in 162 countries will be turning out their lights to raise awareness of global warming and it's effects on our food supply and farming sustainability.

Earth Hour, the world's largest grass-roots movement for the environment, hosts a symbolic “lights off” hour and associated events to to draw attention to tackling global warming and to get people talking about what we can do to help.

Earth Hour launched in Sydney in 2007, with 2.2 million people and 2,100 businesses participating. Just one year later, Earth Hour became a global phenomenon with over 35 countries participating, and an estimated 50-100 million people.

In 2015, Earth Hour is focusing on the current and future impacts of global warming on agriculture.

Events are being hosted all over the country to raise awareness of the effects rising temperatures and more extreme weather like drought and irregular rainfall will have on farms, farmers and our favourite ingredients.

As part of the campaign Earth Hour has launched it's first cookbook, Planet to Plate. The cookbook features recipes from celebrity chefs, stories from farmers about the ways increased carbon pollution is affecting them, and information on how Australians can get involved to safeguard our country’s great food industry into the future.

Earth Hour will be held on Saturday 28 March from 8:30 to 9:30pm.

If you care about our food and farmers, show your support by switching off the lights and hosting a BBQ, dinner, picnic or get together which brings the 'Food & Farming' theme to life.
