The green represents the need for an emphasis on ecological change, whilst the black is in reference to the black anarchist flag (here’s some historical context).
The red 8-sided asterisk represents the urgency for communities to cooperate in ridding the planet of eco-fascism. I picked the 8-sided one to represent the worldwide need for change.
Edit: anarcho-communism is not a type of fascism. Y’all do realise that this is a leftist Lemmy instance, right?
No? If you’re unfamiliar with Anarcho-communism, then I’d suggest taking a look at this documentary. It’s a political philosophy that goes back to the 1800’s.
