Greta is doing an immense service for all of humanity, but many people are needed to fight the climate crisis. The climate scientists have already defined the problem - there's too much CO2 in the atmosphere. The engineers and technicians are developing solutions. The gov't will legislate funding for the solutions if, and only if, the activists like Greta wake up enough people who push for action. Until then, nothing happens. The oil corporations are fighting hard to make sure nothing happens. If nothing happens, we are headed for a climate catastrophe of biblical proportions. That's it in a nutshell.
