Australia's National Sustainable Living Festival
The National Sustainable Living Festival happens all the way over in Australia and they have one mission: "accelerate the uptake of sustainable living and to seek solutions to global warming" (according to http://ow.ly/vhSs50nZpXN). With over 100,000 people attending the event every year. They organise a weekend of multiple events that show people how they can become more environmentally friendly as well as getting people together to create art structures out of rubbish etc.
How could your event encourage people to do more for our planet?
could you use everyday rubbish to create something artistic or just put it to practical use?
