We're Doing it for the Polar Bears: WWF Earth Hour

We're doing it for the polar bears, but you can do it for any endangered species you like. The World Wildlife Federation is sponsoring an "Earth Hour" on Saturday, 28 March from 8:30 p.m. in whatever time zone you live in. As this seems a somewhat flexible time, I say that parents can use whatever time zone the whole family can participate in, so for us, we'll be using European time (one hour earlier than London, making our Earth Hour from 7:30 p.m.

The idea is that we all switch off our lights for one hour to show that you care about people, wildlife and the planet.

Some 1180 cities from 80 countries across the globe have already signed up. In addition, a great number of iconic landmarks will be plunged into darkness, including Nelson’s Column, the Forth Bridge, the Millennium Stadium in Cardiff, the Eiffel Tower, Christ the Redeemer in Rio de Janeiro, Table Mountain in Cape Town and Sydney Opera House. The London Eye, too, will be dimmed for the hour.
