I think that the young children of today experience the same thing. We talk about how the earth is heating up. How the permafrost is melting. How the sea level is rising (this one is especially fun in the Netherlands given that most of the country is below sea level). How people, animals, entire species will die. A person who's roughly my age or older is able to understand the severity of the situation, but at the same time is able to understand that there are things we can do, and that we are in fact doing things, which makes me hopeful.
But I can't help but feel a little for the 10 year olds of today who watch the news every evening with their dads.
