We don t leave behind things we don t want. In plants we have moved away from antibiotic-resistant genes. We just use the genes we want. I can t guess. There is a need for early education about science, using programs such as the Academy s Primary Investigations .
Primary science is very important.
There are limitations to how much you can educate the general public. Some people just regard certain things as unnatural, for example they believe that natural chemicals are different from laboratory chemicals. There are some who won t buy a synthetic food colouring or flavouring, even if they have the same chemical structure as the natural ones. We are unlikely to be able to convince these people that GMOs are beneficial.
