Greta Thunberg - Environmental Activist

Greta Thunberg is a Swedish environmental activist who is known for challenging world leaders to take immediate action for climate change mitigation.

Thunberg’s activism began when she persuaded 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 (School strike for climate).

Thunberg initially gained notice for her youth and her straightforward and blunt speaking manner, both in public and to political leaders and assemblies, in which she criticizes world leaders for their failure to take what she considers sufficient action to address the climate crisis
