If the bad things are going to happen, there’s little we can do to stop it, once it has been set into motion (no one person led to climate change). What we can do is control our response. We can do our best to mitigate what risks we can, and ultimately we can do our best to make the most of the situation we are in. That’s the one thing we can do as individuals to make things better for our future selves and our descendants, we can be compassionate to those around us and work to inspire our communities to do that too.
All in all, nothing tonight that you can think up will change the climate or the world’s response to it. We can worry about the future, but we only will know what the future holds as it occurs, so it doesn’t do much good to assume that the worst is necessarily going to happen. Catastrophizing sucks, and I know what you’re struggling with right now. Perhaps a counselor/therapist could help you understand and manage your anxious thoughts. You’re definitely not the first or only one to have these fears, so don’t feel bad about it. I hope some of the comments put you at ease and help you get some rest.
I think this is the original artist. It is the earliest upload of the image i’ve seen.
