"This week marks two anniversaries of global green campaigning groups that could scarcely be more different, while holding almost identical aims."

"On Thursday, Greenpeace turns 40 – an unlikely candidate for middle age, given its activists' reputation for eye-catching and sometimes dangerous stunts. Last Sunday, WWF celebrated 50 years since the opening of its first office in Switzerland – a much more staid affair, as befits an organisation that boasts the support of the Prince of Wales and the Duke of Edinburgh."
