It stars well, then gets weird. "Is there some level of carbon tax at which we would forego every lake on earth rather than apply it?" Obviously, there isn't (+infinity), because of diminishing marginal returns. Everything is a tradeoff. That's basic economic theory, so yes it applies to the environment. And if you want to figure out how much people care about lakes and nature, you can use existing data about cities adding or removing parks - you'll see people like nature, but not so much as to pay +infinity tax. Because, you know, diminishing marginal returns - again.
