We may be able to tackle pollution, global weather meltdown and other issues by changing the ways we live, though once there is enough GMO pollen out there; once enough of the food chain is contaminated, we will never be able to recall them.
GM plants cannot be recalled, but as living organisms they will multiply and mutate, passing any damaging traits from generation to generation.

If it was any other product or non-living chemicals, it would have required much more stringent tests or clinical trials.
Since these are living organisms, the remedies need to be much stronger than the protection (patent and licensing) of the same.
How can the world reverse this?
