Are you ready to do your bit to stop glo

Are you ready to do your bit to stop global warming? On Saturday, March 29, you will have a chance-to tell Toronto and the entire world that you are devoted to doing your part.
You can do it by turning off your lights during Earth Hour, from 8 p.m. to 9 p.m. Started last year by the World Wildlife Fund in Sydney, Australia, Earth Hour this year is going international, with 17 cities signed up so far, including Toronto.
The challenge for us Torontonians will be to show we are as devoted to fighting global warming as Sydneysiders were last year. Of course, one hour of darkness isn't going to stop global warming. But the thinking behind Earth Hour is that it gets people personally involved(加入). Besides giving people a chance to show their concerns over climate change, the goal is to get them to start changing their wasteful habits. Did you know, for example, that your electronic devices(设备) that you think you've turned off are still drawing power if you leave them plugged in?
If you want to make a difference, sign up today and promise to turn off your lights when Earth Hour arrives on March 29. Persuade others to do their part. Start to think about changes that can be made in your home and your workplace that will cut down on waste and greenhouse gas.
