In August 2018, a quiet protest outside the Swedish Parliament unexpectedly became one of the world's biggest environmental movements. A 15-year-old student named Greta Thunberg skipped school every Friday to demand stronger action against climate change. Holding a handmade sign reading "Skolstrejk för klimatet" (School Strike for Climate), she stood alone—at first.

Photos of Greta's protest quickly spread across social media, inspiring millions of students around the world to organize their own climate strikes. Within months, the movement known as Fridays for Future had expanded to more than 150 countries, with participants calling for governments to take climate change more seriously.

Greta soon addressed world leaders at international events, including the United Nations Climate Action Summit. Her passionate speeches, especially her famous "How dare you!" address in 2019, sparked global discussions. While many praised her courage and determination, others criticized her views, making her one of the most talked-about public figures of the decade.

Regardless of differing opinions, Greta's influence is undeniable. She transformed a solo protest into a worldwide movement that encouraged millions of young people to become more engaged in environmental issues.

Fun Fact: What started with just one student, one sign, and one sidewalk eventually became one of the largest youth-led movements in modern history. Sometimes, changing the world really does begin with showing up. 🌍💚
