Strongly agree.
Corporations can't be trusted because consumers can't be trusted. Even if each tissue chopped down a rainforest, you can bet that at least 10% of consumers would buy those tissues if they were 50 cents cheaper. In addition, the consumer body at large won't react to environmental issues until they've already crossed the line into a crisis. Government action and environmental regulations are thus needed.
I think this sums up the core of the problem. Corporations aren't evil; they're just amoral (not immoral) collectives answering the demands of consumers: low prices at any cost.
