This from Do Something About It: I can't make the rally (but I'm looking forward to attending the 'Financial Fools Day!' and Climate Camp protests next Wednesday) - but I will be turning my lights off!
The Put People First rally is not the only event that's taking place tomorrow.
If you can't make it to the march, you can still participate in a protest of global significance - and you don't even need to leave the house.
To campaign against climate change, all you need to do is turn off your lights between 8.30 and 9.30pm. The organisers of Earth Hour aim to collect millions of 'votes' from around the world, which they will then present to politicians at the Global Climate Change Conference in Copenhagen later this year.
Wherever you are in the country, wherever you are in the world (if you're outside the UK, just flip the switch at 8.30pm local time wherever you happen to be), this is a great opportunity to show politicians that you're taking global warming seriously - so they better do so too.
And while we're at it, here's a great video which explains what's wromg with carbon trading:
