Ethical considerations at the various stages in the development, production, and consumption of GM crops

The aim of this paper is to clarify the ethical issuessurrounding GM crops by examining the various stages or levels intheir development, production, and consumption. Previous workabout the acceptability or non-acceptability of GM crops hastended to conflate these various levels, partly as a result ofwhich GM crops are all-too-often simply said to be ``good'''' or``bad.'''' There are, though, various problems with such a binarycategorization. I look in particular at the duties of scientists,companies, regulatory systems, farmers, retailers, and consumers.
