So how do you do that? How do you target capital holders?

I'm not asking people to boycott anybody. I agree that corporations are the majority of the problem not consumers directly. But change in consumer habits towards products and companies that care about the earth and don't have harmful outputs or at the least drastically reduce them seems to me like a not unreasonable request.

Unless you're of the opinion that corporations do not or will not change to adapt to consumer preferences?

I don't know what a reasonable timeline is but if in the next 5-10 years there continues to be this push for environmentally sustainable consumerism corporations will change to appeal to that.

Its the most concrete and realistic and plausible solution. Especially when compared to going head to head against corporate lobbying and appealing to a companies sense of ethics and humanity.

I don't see how any other proposed option is as plausibly gonna lead to real change.

Corporations WILL change if people do. Its just that people don't want to. And yet we expect others factors and people to change when we as individuals dismiss and refuse to.
