Are you ready to do your bit to stop global warming? Do you want to let the world know that you believe it is not doing nearly enough to fight climate change?

On Saturday, March 29, you will have a chance to communicate your concerns—to tell Ottawa 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. Others include Chicago, Manila, Tel Aviv, Copenhagen, Melbourne, and Christchurch, New Zealand.

The challenge for us Torontonians will be to show we are as devoted to fighting global warming as Sydneysiders were last year, when more than 2.2 million of them participated and slashed the city's power use by 10 per cent for the planned hour.

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. Besides giving people a chance to register their concerns over climate change, the goal is to get them to start changing their wasteful habits. And we all have them, including some we aren't even aware of.

Did you know, for example, that you are still drawing power if you leave your cellphone charger plugged in after charging your phone? The same is true for other electronic devices that you think you've turned off.

If you want to make a difference, sign up today at http://www.wwf.ca/EarthHour and make a pledge (宣誓) to turn off your lights when Earth Hour arrives on March 29. Persuade your friends, co-workers and your employer or employees to do their part.

But don't wait for this symbolic gesture to raise awareness that we all have to be part of the solution. Start today to think about changes that can be made in your home and your workplace that will cut down on waste and greenhouse gas emissions (排放).

One thing that every dog needs to know how to do is sit. Teaching a dog to sit is probably the easiest trick in the book. Dogs learn to sit by praise. You must first introduce them to what sitting is.

   Gently place your hand over the top part of their bottoms and gently push down. Once you have got them into the sitting position, say “sit”. Now, make sure that they have sat down and give them a treat for praise. Wait a while before doing it again because each time you do it, you will be rewarding them for it.

   Using treats while training your dog to sit will help him or her learn a lot easier. He or she might think, “Okay I get it, so when I sit, I get a treat!” So in the beginning, give your dog a treat every time they sit. At first, when you are training your dog to sit, they will feel puzzled. This is very normal because sitting is new to them. Dogs favor routine(常规), and once sitting becomes a part of their daily routine, it will be something that they truly enjoy doing for their owners when asked.

   Young puppies are often the easiest to train to sit. Sitting is a simple and easy command that can be taught to any dog. Older dogs may learn a bit more slowly, but this is simply because they have got into much more of a routine. Do not think that your older dog cannot learn how to sit. It just takes time.

If you are having a seemingly difficult time teaching your dog to sit, you may need to go to your nearest library and rent a book on your particular dog family. Different dogs have different tempers. What is normal of one dog may not be so true for others. There are many things that will decide whether your dog has an easy time learning how to sit, but most of it will be up to you.
