In August 2018, Greta Thunberg started a school strike to push recognition of our planet’s climate emergency outside the Swedish Parliament that has since spread all over the world and now involves millions of school children and adults of every age. The movement is now called Fridays For Future. Thunberg tries to live a low-carbon life. Therefore she is vegan and doesn't fly. She has been named as one of the world’s most influential teens by TIME magazine.
Many things are extraordinary about Greta. She is very intelligent and a gifted speaker who carefully chooses her words. But what helps make her such a leader is both her conviction and the fact that, in spite of her age, she really understands what she’s talking about. Youtube one of her speeches and see for yourself.
Learn from her: take the time to deeply understand the topics you’re concerned about so your own words and actions will carry weight and you can thereby have the most impact on changing the world.
