Um, you could use household items with a good energy rating... sponsor programs run by ACF, WWF or Greenpeace... drive a smaller car or use public transport... swtich off the air-con & get a fan... Participate in clean up Australia Day... make a compost heap... help with rallying the Govt to sign Kyoto or invest more money in the so-called environmental schemes... switch to green power (ask your provider).
Many things... but the biggest is political pressure. I mean, there's 20 billion per year going to the aluminium industry to subsidise their energy use, but only 1 billion going to envirnmental programs...
Not good eh?
Ok, it's not good enough but it's all we got! And it's better than anything the Aussie govt has come up with so far.
In fact, we're losing more money by NOT signing it.
