That's the whole principle of sustainable development. I would argue that, in the past, economics was the only thing looked at. Then we added the social aspect. Usually socio-economic goes together. That's the analysis that's done. That's the lens taken on most decisions, and most decisions don't have a lens that includes the environmental lens. When we include that, at least we're aware of what the opportunities and impacts will be of making that decision on all three parts of the sustainable development stool.
