2019 has been a year of youth activism. From the Swedish climate change protester Greta Thunberg to Hong Kong’s democracy activist Joshua Wong, young people have been making headlines.

And what does it take to become the next Greta Thunberg? Paul Henley and a panel of experts discuss the young people trying to change the world.
