Yikes - it's Halloween again. (So soon? How'd that happen?)

That plan to wrap your head in aluminum foil and go out as a serving of Jiffy-Pop suddenly seems like too much trouble. So why not try being an internationally respected icon of environmental stewardship and famous broadcaster, David Suzuki? You'll be able to crash just about any party you want. Who's going to turn away David Suzuki?

Download his face, print it at home, attach your own string, colour it in if you're feeling ambitious, and you're done - ready to frighten climate-change deniers, polluters and gas-guzzling non-recyclers throughout your neighborhood.

To complete the illusion, bring along our leaflet so that you can invite your friends to join us in the Nature Challenge. You can also print the leaflets (PDF) to hand out to visitors who come knocking on the big night.

There's no trick to stopping global warming. Treat yourself today to the Nature Challenge!

Happy Halloween from the Nature Challenge team.
