We're in a position with a lot of power, but this is obscured from us. When we trace the strings which run from ecocide to ourselves, it is easy to see what changes we need to make.
Have you stopped buying the myriad "cleaning" products which pollute your home and create pollution in the process of being produced?
Have you stopped buying disposable clothing and plastic trinkets?
If you are still buying these things, you are complicit in this ecocide. And now you know it, too.
Once you stop yourself, you can tell others, too.
Without making changes in your own actions, there's little you can ask of anyone else.
This is a change that will come one individual convincing another individual, one at a time, to stop contributing to the problem.
No one else will do it for us: politicians don't give a fuck, corporations don't give a fuck, regulators don't give a fuck, military doesn't give a fuck, even "scientists" are mostly in the same camp of not giving a fuck, for the most part.
We are the only ones who give a fuck, because it's our close relatives, and soon, us, who are being exterminated.
And we are feeding and building our own extermination machine.
If they stopped single-use plastics, that would be a world first. Microbeads were recently banned; this is obviously orders of magnitude more effective than boycotting microbead-containing hygiene products would ever have been.
By all means, reduce your personal consumption of harmful products. Don't fool yourself into thinking it's a substitute for activism and political action.
If half the world stops burning fossil fuels tomorrow, the other half will enjoy cheaper oil and double their emissions the next day. Tax pollutants.
