The second annual Earth Hour takes place at 8pm local time tomorrow (March 29th). The idea is that people turn, companies and cities turn off their lights for an hour to help inspire people to take action on climate change. It started in Sydney, Australia last year with something like 2.2 million people and 2100 businesses in Sydney turning off their lights for an hour on March 31st. Since then, it has become a global movement with more than a quarter of a million people and a large number of companies and cities committing to turning off their lights for an hour.

Locally, the City of Ottawa has joined the Earth Hour movement. Personally, I’m going to turn off my lights for the hour.

What are you going to do? If you’re not doing anything, why not?

Since implementing the captcha challenge for comments on my blog about a week ago there hasn’t been a single comment trapped by Akismet.  Normally, there would have been about a hundred comments during that time that I would have had to review to make sure there were no false-positives, so I think it’s safe to say that it’s working.
