This seems like some cherry picked bulshit. I’m an ecologist and a parent and i do not lie to my kid, nor do any of the other parents i know wotking in the natural sciences. Truth is best, the world is falling apart because of a handful of powerful people can’t stomach the extremely viable solutions. We are at war, if you see it or not, and not preparing your kids is negligence.
Fight back. If you are contemplating the fear of death from climate change, then the courage to fight those responsible should seem like a relativity small hill to climb.
