His thesis is that we are doing quite well in terms of life expectancy and quality of life, worldwide. I agree with that but left the following comment:
- Environment is, at best, indirectly improving with the expansion in our living standards. Without a price on clean air, etc., there is little reason to assign positive value to it [and it gets overused].
- Adaption to climate change will be easier for rich countries, but what about LDCs? They will not be able to save themselves with an iPad app.
Bottom Line: Things are getting better, but we have to make sure that we take all costs of growth into account.
