//Suited her or her handlers, remember she was only 16 when she started//
She started a lot earlier than that, Webbo. Cribbed from Wiki (and confirmed by her mother in her latest book):
"Thunberg says she first heard about climate change in 2011, when she was eight years old, and could not understand why so little was being done about it. The situation made her depressed. She stopped talking and eating, and lost ten kilograms (22 lb) in two months. Eventually, she was diagnosed with Asperger syndrome, obsessive–compulsive disorder (OCD), and selective mutism. In one of her first speeches demanding climate action, Thunberg described the selective mutism aspect of her condition as meaning she "only speaks when necessary".
Instead of tackling the problems their daughter had her parents merely indulged her:
"For about two years, Thunberg challenged her parents to lower the family's carbon footprint and overall impact on the environment by becoming vegan, upcycling, and giving up flying. She has said she tried showing them graphs and data, but when that did not work, she warned her family that they were stealing her future. Giving up flying in part meant her mother had to give up her international career as an opera singer. Interviewed in December 2019 by the BBC, her father said his wife stopped flying to try to 'save' their daughter rather than the climate. He added: "To be honest, (her mother) didn't do it to save the climate. She did it to save her child because she saw how much it meant to her, and then, when she did that, she saw how much (Greta) grew from that, how much energy she got from it."
Frankly her childhood problems were handled appallingly by her parents. An eight year old child suffering from depression needs treatment and support, not simply indulgence. There is no way they should have altered their lifestyle to such a degree. It is terribly sad to see a teenage girl displaying such symptoms and she can only be described as a mental and emotional wreck.
I have a nephew who, when he was about ten, was taught about "germs" and their dangers in school. It had a profound effect on him. He became withdrawn, would not have a window open and would rarely go out. He was knocked into shape by his parents (ably assisted by his aunt and uncle) who diverted his attentions elsewhere. Now he is as normal as me (Oh! Hang on!). But seriously, the childhood treatment of Ms T is bordering on criminal. And now her very troubled mind has another burden to trouble it even further.
