Greta Thunberg

Greta Thunberg (born 3 January 2003) is a Swedish environmental activist who is internationally known for challenging world leaders to take immediate action for climate change mitigation.[4] Thunberg initially gained notice for her youth and her straightforward speaking manner,[5] both in public and to political leaders and assemblies, in which she criticises world leaders for their failure to take what she considers sufficient action to address the climate crisis.
