So we're relying on do-gooders to look into the environment? I don't see how they would have the funding required. There's a huge amount of money that's gone into research on climate change and I don't see where that would have come from. Once it's out there I understand how a company might see it as an opportunity for differentiating itself but I don't see how the knowledge would come about in the first place. Climate change is not comparable to hotel reviews in terms of money/effort/time and other resources required to gain an informed opinion from scratch.
