By training, I am a plant biologist. In the early 1990s I was busy making genetically modified plants (often called GMOs for Genetically Modified Organisms) as part of the research that led to my PhD. Into these plants we were putting DNA from various foreign organisms, such as viruses and bacteria.
I was not, at the outset, concerned about the possible effects of GM plants on human health or the environment. One reason for this lack of concern was that I was still a very young scientist, feeling my way in the complex world of biology and of scientific research. Another reason was that we hardly imagined that GMOs like ours would be grown or eaten. So far as I was concerned, all GMOs were for research purposes only.
