Some opposition to safe genetically modified foods is based on the ethical argument that people simply have no right to tamper with nature.  But according to a commentary by Samuel Gregg of the Acton Institute for the Study of Religion and Liberty, this criticism is surprising, especially from wealthy nations in Europe which have historically embraced the Judeo-Christian understanding that people should exercise reasonable dominion and stewardship over the earth.  He points out that long ago, our ancestors engaged in cross-breeding and cross- fertilization to make food safer and more plentiful, and that such beneficial progress is certainly needed today with large numbers of  hungry people around the globe.
