The distraction is that I just found goodreads.com; I have been not only reading more, but finding more to read and reviewing what I have read.
A readable survey of developments of genetically modified foods (and fuels)and resistance to them, of their successes and failures, of their oversights and limits. It is written by an academic, a cell biologist, but written so that a layperson can understand the issues. There are source notes in the back so as not to intrude, but to be there for the reader who wants to follow up.
Especially interesting are the chapters presenting the non US perspectives: Zambia, India, and Thailand.
It is neither for nor against genetic modification, but it is for transparency, safe handling, labeling, and public good rather than corporate profit.
