Thunberg is a Swedish environmental activist who became famous last year when she said she refused to go to school on Fridays until politicians complied with the Paris Climate Agreement.
Thus, it attracted the attention of the world and has since quickly become almost the main symbol of modern environmental activism.
Now Greta is called an "icon" by many, and leading publications add her to the list of the most influential people in the world.
In September this year, Thunberg addressed the UN General Assembly and was again in the spotlight: a 16-year-old girl made an emotional speech in which she accused world leaders of insufficient fight against climate change.
