It's a shame Greta Thunberg's advisors, assistants, helpers, etc all fly around getting supplies & setting up meetings. Instead of, you know, the more carbon-efficient method of traveling the ocean via maritime ships.
Great Thunberg's coterie of helpers have a larger carbon footprint than the majority of us.
But hey ... at least it's not as bad as Prince Harry, who said every action matters (when telling the plebeians to stop their commercial air travel habit), and then took 4 private flights over the next two weeks.
Gotta love Gulfstream environmentalists.
