False dichotomy, it’s all of our fault. We are all perpetuators of the system, some small, some large. Just like with cocaine, placing all the blame on the producers and ignoring the massive demand and the reasons for it isn’t how drug problems are solved.
For things to change, we all need to change, if your effect is small because you’re just a person, the needed change is small, like buying less and making better choices. If you’re a large perpetuator like a company, the needed change is large, up to and including stopping or radically altering operations because they are fundamentally unsustainable (e.g. Exxon).
In a capitalist world, if there’s a demand it will be supplied consequences be damned.
