Climate activist GretaThunberg, who was just named Time’s Person of the Year, called out world leaders for not doing enough to stop the planet’s ecological crisis at the #COP25 conference in Madrid on Wednesday. “The real danger is when politicians and CEOs are making it look like real action is happening when, in fact, almost nothing is being done apart from clever accounting and creative PR,” the 16-year-old activist said. Around 25,000 people from 200 countries were expected to attend COP25, the last gathering of the group before 2020, the year the Paris climate accord goes into effect.
