Please consider this. As a parent of a teenager I know a fair number of teenagers are crushed by fears of what climate change will do.
It's a horrific burden, it will crush a child's soul. We can make the environment cleaner with our technology, but changing the weather to prevent climate shifts that occur on a geological time scale and involve a nuclear furnace of a scale beyond our wildest imagination is not within our control.
Teaching your children that all the beauty of the planet is going to die because "people are bad and can't get their shit together" is a completely fucked parenting strategy and a horrible, awful, thing to do to children.
Even if it's true it's much kinder to let them live out this normally happy time of their life in blissful ignorance.
Kindness is what life is about.
