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.

Gradually, however, it became clear that certain companies thought differently. Some of my older colleagues shared their skepticism with me that commercial interests were running far ahead of scientific knowledge. I listened carefully and I didn't disagree. Today, over twenty years later, GMO crops, especially soybeans, corn, papaya, canola and cotton, are commercially grown in numerous parts of the world.
