Genetically modified (GM) foodstuffs are here to stay. That2s not to say that food produced by【1】agriculture will disappear,【2】simply that food buying patterns will polarize. It may even be that GM food will become the food of【3】because consumers come to appreciate the health benefits of reduced【4】use.
The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep【5】with the world’s【6】population growth to ten or eleven billion.

Genetic engineers like me are not doing anything as【18】as making a cabbage into a cauliflower—【19】has been done by plant breeders in the past. We’re simply tapping into the whole gene pool,【20】concentrating on one species at a time.
