Greta Thunberg is an amazing human being. She is sincere and passionate about taking climate change seriously and began protesting inaction in Sweden when she was just 15. She was roundly criticised for being young, for being autistic and for being irritating, but that is just the point. You don't grow a pearl without irritating an oyster.

I consider her, like Malala Yousafzai, to be one of the young heroines of the 21st Century.
