Greta Thunberg (an environmental activist on climate change, born 3 January 2003) has inspired a number of her school-aged peers in what has been described as "The Greta effect” and is now the face of a global youth-led climate movement. Greta is known for her blunt, straightforward speaking manner, both in public and to political leaders and assemblies, in which she urges immediate action to address what she describes as the climate crisis. She was nominated for the 2019 Nobel Prize and is Time’s person of the year for 2019.
