LONDON (Reuters) - Britains Prince William launched a multi-million-pound environmental prize on Thursday, teaming up with celebrities including footballer Dani Alves and Alibaba founder Jack Ma to launch a prize aimed at tackling the worlds climate problems.

With the high-profile project, William, the Queens grandson who is second-in-line to the throne, opened up a new chapter in the royal familys decades-long environmental campaigning.

The Earthshot Prize will award five prizes worth nearly $1.3 million each year for the next 10 years under the categories of protecting and restoring nature, cleaner air, reviving oceans, waste-reduction and climate change.
