The Canary Wharf financial district is seen during mid-evening in East London March 26, 2009.
Tenants in the Wharf area are among the organisations getting involved with the World Wildlife Fund's "Earth Hour," which will see over 2,000 cities in over 80 countries switch off their lights at 20:30 local time. Event organisers predict it will be viewed as the world's largest gesture on climate change to date.
