No, I am not one of those that make fun of the girl. I admire her and fully support the effort. From a communications point of view, Greta Thunberg greatly helped both bring forward important issues and the idiots that oppose global warming initiatives with no valid scientific or logical counter-arguments. In fact, I have an idea to cut emissions immediately, drastically and effectively.
Shave your head.
In fact don’t shave it, use a machine, less waste. If the entire planet shaved their heads the benefits would be enormous. I challenge some universities to calculate them in detail. We start of course with shampoos and conditioners and all those other hair washing products, their plastic containers, moving them across the globe, disposing of them. Then there is the water wasted in hours of washing hair, the energy to heat that water. Chemicals, gels, dyes, poisoning us and the planet. Electricity wasted drying hair, straightening or whatever else you do to hair. Time and energy wasted going to hair salons and all other trips related to hair. If we run the entire chain backward and eliminate hair care, I am pretty sure we can shave off 1 degree Celsius from the planet just by shaving our heads.
Starting with Greta.
