Those are examples, not requirements. Do what you can. Anyone who judges you for not doing enough while you're struggling to merely survive is a shit person.

If there are small changes you can make to live a more sustainable life, do them. If there's nothing you can do, that's okay too. And if you're so weighed down by the struggle of mere existence that you don't have the mental energy to think about ways to change - that's okay too. We who have the privilege to act should act, and when we do, we carry the aspirations of those who wish they could act but can't.

If I meant to criticize anyone by this post, it would be the people in wealth and privilege, who could change their lifestyle to be more sustainable - who could be an example to their friends and family and neighbors by living their values - but who choose not to, because they believe personal sustainability is irrelevant when political and corporate actions have so much more impact on the world.
