If the people in a position to do something about it, actually did what they wanted, ie; demolished all oil/coal power stations,
used solely wind and wave power, they'd most certainly get plenty of time off school, as most would be shut.
What do they expect the government(s) to actually do? Do the above and the economy is completely gone, no more mobiles,
cars, TV's, in fact virtually everything. It's all very self satisfying and worthy but ultimately, it's futile, what would be a more
powerful message would be collectively not using phones, walking everywhere and not flying abroad, using a school day
to bunk off is much easier. Climate change is an emotive subject, for sure, my personal take on it is it is impossible
to halt without population control,because a fast increasing world population is the fundamental reason behind it.
