People are not talking about an existential threat
Greta says that when she was eight years old, she was “thinking that it was very strange that humans, who are an animal species among others, could be capable of changing the earth’s climate. Because, if we were and if it was really happening, we wouldn’t be talking about anything else.” Ironically, she realized that “No one talked about it. Ever,” which indicates that people simply do not seem to care about climate change.
Seeing in "black and white"
Greta has Asperger’s syndrome but ironically she thinks that “in many ways that we autistic are the normal ones and the rest of the people are pretty strange.” After all, the “normal ones” declare that climate change is an existential threat, yet carry on like before.
The hypocrisy of rich Western countries
Greta highlights the hypocrisy of rich Western countries. They expect emerging countries such as Nigeria or India to care about the climate crisis, but ironically the rich countries “don’t care even a second about it or our actual commitments to the Paris Agreement.”
Environmentalists
Greta emphasizes the irony of the environmentalists’ behavior as well, who say one thing and do another: “Even most green politicians and climate scientists go on flying around the world, eating meat and dairy.” According to her, this behavior does not make the climate crisis seem like an important issue.
Asperger's as a gift
While some people may consider Asperger’s syndrome a disease or disability, Great considers it a gift. She says that if she had been “normal,” she would have joined an organization to fight climate change, but since she is not good at socializing she chose to start the movement on her own.
