I’m not particularly worried about whether her individual boat is green or not, because there are plenty of other boats which are not green, and perhaps great minds could be put to use to remedy that problem.
However, with regard to this young girl, who is being manipulated in my opinion, one wonders why she’s not due to be back in school/college in September, rather than touring America, presumably preaching about climate change. As a parent, I would not have allowed my teenagers to miss out on their education. Only with education can we hope for the changes which are necessary. Perhaps we should be putting more resources into science education instead of closing down science courses in some universities as is happening now. Greta should be heading home to continue her education in my opinion. She certainly has the drive to become a great scientist, rather than virtue signalling to the rest of the world, half of whom live in poverty and have no interest or influence with climate change. Greta could do so much more with her life really.
