On challenges

The CP reports on Tim Harvey's zero-emissions journey around the world in an effort to raise awareness of global warming. Harvey deserves plenty of credit for drawing attention to the issue, but it's hard to disagree with the comment of a David Suzuki foundation spokesman:

Ian Bruce of the David Suzuki Foundation said Harvey's efforts at raising awareness of what he calls the "greatest threat facing humanity" are crucial.

But he reminds Canadians they don't have to go to Harvey's extremes to make a difference.

"People shouldn't feel alone. Canadians feel this is a top priority," Bruce said.

In a sense, the metaphor of a harrowing journey around the world could only make tackling global warming appear both distant and difficult...when in fact many of the answers are already readily available and accessible. And hopefully that fact won't get lost as Harvey finishes the last leg of his trip.
