The investment business has taught me – increasingly as the years have passed – that people, especially investors (and, I believe, Americans), prefer good news and wishful thinking to bad news; and that there are always vested interests to offer facile, optimistic alternatives to the bad news.

The language "it's too late" is very unsuitable for most environmental issues. It's too late for the dodo and for people who've starved to death already, but it's not too late to prevent an even bigger crisis. The sooner we act on the environment, the better.

You don't actually find a strong correlation between- top-line GDP growth and making money in the market. It- it seems like you should. The fastest-growing countries should give you the highest return. They simply don't. But, there's only four of us- that- that believe that story. Everyone else in the world believes that if you grow fast like China, you'll outperform in the stock market.

The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.

...how little our side of the industry did to move its business to the more ethical firms and to make a fuss about conflicted or unethical behavior. Had a number of us moved our business, we might have slowed or even stopped the 30-year slide in conflicted, unethical behavior that we have experienced. I, for one, regret the modest nature of our moves. We all could have done more. We have tolerated a pretty nasty decline in standards. Shame on us.

The potential for alternative energy sources, mainly solar and wind power, to completely replace coal and gas for utility generation globally is, I think, certain. The question is only whether it takes 30 years or 70 years.
