> only be accomplished through collective action

I'd agree if you said enforced collective action. We cannot rely on companies to self-regulate. There needs to be severe consequences for companies that damage the environment like this. As long as profits far exceed penalties, companies will continue to take the easy path.

I think it's pretty clear from the context he's not talking about corporate action, but citizens' action.

Corporations also have civic responsibility.

Any collective, corrective action must include corporate action, or it is futile.

I believe the point was collective action of citizens leading to governmental action to enforce corporate action.

Perhaps stop buying the offending company's products?

You're making the perfectly informed consumer argument? They don't exactly put warning labels on the packaging. "The company which produces this product does disproportional damage to the environment."
