Matt has taken the bait and asked me a five good questions about my snarky, contrarian post on climate adaptation. Here are his questions and my answers. Question 1. This paper will be published soon by the JPE. Costinot, Arnaud, Dave Donaldson, and Cory B. Smith. Evolving comparative advantage and the impact of climate change in agricultural markets: Evidence from 1.7 million fields around the world. No. w20079. National Bureau of Economic Research, 2014. http://www10.iadb.org/intal/intalcdi/PE/2014/14183.pdf It strongly suggests that adaptation will play a key role protecting us. Which parts of their argument do you reject and why? Answer: This looks like a solid paper, much more serious than the average paper I get to review, and I have not yet studied it. I’m slow, so it would take me awhile to unpack all the details and study the data and model. Although, from a quick look, I think there are a couple points I can make right now. First, and mo
You muddy the waters by calling this "genetic modification".
ReplyDeleteTraditional crop breeding/improvement has virtually none of the downsides of GMOs.
Of course it could be argued that there are benefits to GMOs. Just don't call it all genetic modification.

Controversies
* Safety
o Potential human health impacts, including allergens, transfer of antibiotic resistance
o Potential environmental impacts, including: unintended transfer of transgenes through cross-pollination, unknown effects on other organisms (e.g., soil microbes), and loss of flora and fauna biodiversity
* Access and Intellectual Property
o Domination of world food production by a few companies
o Increasing dependence on industrialized nations by developing countries
o Biopiracy, or foreign exploitation of natural resources
* Ethics
o Violation of natural organisms' intrinsic values
o Tampering with nature by mixing genes among species
o Objections to consuming animal genes in plants and vice versa
o Stress for animal
* Labeling
o Not mandatory in some countries (e.g., United States)
o Mixing GM crops with non-GM products confounds labeling attempts
* Society
o New advances may be skewed to interests of rich countries
