I think one must be living in a cave with no outside connections at all to have heard about climate change. The problem isnt that people dont know about it, its not even that they dont care about it.
It's more, what can we really do. Our lives generally revolve around getting to work, having a decent home. These things require travelling somehow and building homes. Both things not conducive to changing climate. Both things us the gen pop can do fuck all about.
And then you'll see some hob nob or official or minister or sleb flying to faraway places, possibly in a private jet. Then you think oh it's ok for you to fly places, but I'm supposed to stay local. Hypocrisy at its finest.
