Greta Thunberg
Greta Tintin Eleonora Ernman Thunberg is a Swedish environmental activist who is internationally known for challenging world leaders to take immediate action for climate change mitigation. Thunberg initially gained notice for her youth and her straightforward speaking manner, 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. Thunberg's activism began by persuading her parents to adopt lifestyle choices that reduced their own carbon footprint. In August 2018, at age 15, she started spending her school days outside the Swedish Parliament to call for stronger action on climate change by holding up a sign reading Skolstrejk för klimatet. Soon other students engaged in similar protests in their own communities. Together they organised a school climate strike movement under the name Fridays for Future.
