Millions of people - both young and old - around the world are demonstrating for the environment today with protests for climate action in over 100 places just in Sweden.

It is the third global demonstration of its kind, and will encompass more than 150 countries, from Australia to America, to Mynttorget in Stockholm, where it all began when the Swedish climate activist Greta Thunberg started her strike from school for the climate.
