> But what this model gives us is a precise, global picture: We can now predict the benefits biodiversity provides anywhere, making it even easier to recognize and take advantage of those benefits."

Shouldn't they simultaneously study the costs of biodiversity? For example, our species left highly biodiverse jungles for less diverse plains, and our bodies are designed to follow and prey on large herbivores that don't do jungle. Less biodiversity creates niches for new diversity. It isn't possible to understand the benefits without the costs.
