Greta Thunberg says she wants a new bicycle light for a gift as she turns 18

Greta Thunberg is hoping to get a new headlight for her bike for her 18th birthday today.

The climate activist was asked what her perfect gift would be as she celebrates hitting this milestone. Speaking to the Sunday Times Magazine, she said she would ideally like "a promise from everyone that they will do everything they can” for the planet but when asked for a specific present, she said; “The headlights on my bike are broken. In Sweden it gets very dark in the winter.” Unlike other teenagers, she wouldn't be interested in being given clothes, insisting she doesn't buy them anymore. The fashion industry is known to be a major polluter. “I know people who have clothes, so I would ask them if I could borrow them or if they have something they don’t need any more. "The worst-case scenario, I guess I’ll buy second-hand." At just 18, Greta is one of the most best-known teenagers in the world. Through her work, she has rubbed shoulders with some of the world's most famous and powerful people; most recently Leonardo DiCaprio, an ardent environmentalist. He's just one celebrity who has been criticised for travelling by plane while speaking out against climate change, but Greta says she "doesn't care". "I’m not telling anyone else what to do," she said, "but there is a risk when you are vocal about these things and don’t practise as you preach, then you will become criticised for that and what you are saying won’t be taken seriously.”
