[NO_CHANGE]

Any mistakes made by biotechnology would be short-term rather than long-term. Absent artificial selection pressures, something like golden rice would quickly revert to regular rice. What usually gets brushed aside is the fact that resources are not unlimited, and it takes extra energy for rice to produce that extra vitamin A, meaning it probably grows slower compared to unmodified rice. If we just left it unattended, not selecting the golden rice kernels for replanting, all the rice would eventually shed themselves of this useless gene that's slowing them down.

Same with the bt crops. The fear about the genes getting out in the wild is greatly exaggerated. Individuals with those extra energy-sucking genes are really at a disadvantage once the selection pressure is turned off.
