10 green royals
8. Queen Elizabeth II of England
Earlier this year, Queen Elizabeth (mother of Prince Charles) planted a chemical-free vegetable garden on a patch of the Buckingham Palace grounds–land that hasn’t seen food production since the Victory Garden days of World War II. The queen has also expressed concerns about the effects of climate change on the poor and made the royal palaces more Earth-friendly by installing energy-efficient light bulbs and even a mini hydroelectric power plant for Windsor Castle.
