Scientists can tend to be a bit dour. We mean to be, because the evidence in which we work is often based in misery as a means of defining what NOT to do rather than what TO do. So, it is interesting and encouraging to see evidence of sustainability (in this case in relation to biodiversity) does have an effect, or is at least correlated with you making more money. I am are sure their are limitations to the function that exists, and I am sure their are outliers (can’t imagine Jabba the Rinehart being interested in sustainability), but there does appear to be evidence that you can be financially well off and have a thriving environment.
