We are all stardust.

That oxygen you breath? That comes from dying massive stars, ending their light in a supernova.

The iron in your blood? Some massive stars dying, but mainly white dwarfs, the leftovers of dwarf stars like our own Sun, exploding.

The gold ring on your finger? Mostly merging neutron stars, leftovers from supernovae.

Prince William telling us to all make the effort to advert climate disaster… the same Prince who hunts for fun, gets ferried around in private jets and eats copious amounts of meat and diary… yeah yeah, whatever. #hypocrisy #practicewhatyoupreach #firststep #govegan #climate #earthshotprize

Good morning! A post just rolled across my fedi-timeline saying not to post about politics on Mastodon, so I'm here to remind you that:

1 "politics" refers to decision-making about how to live together in groups
2 choosing to not participate in political discussion is saying you support the status quo, and is a political stance
3 abstaining from politics because you feel safe from its impacts is a privilege and a choice to abandon your more vulnerable neighbours
