Eliminating GM crops may raise food prices, harm environment

摘要

A study published in the Journal of Environmental Protection shows that a global ban on genetically modified (GM) crops may raise food prices and add the equivalent of nearly a billion tons of carbon dioxide to the atmosphere. Researchers from Purdue University used an extension of the Purdue-developed Global Trade Analysis Project (GTAP-BIO) model to investigate two hypothetical scenarios: "What economic and environmental effects would a global ban on GMO corn, soybeans, and cotton have?" and "What would be the additional impact if global GMO adoption caught up to the U.S. and then a ban were implemented?"
