If you have access to Health Canada's long-term study on the impact for human consumption, I would be really happy to see it, because I think nothing exists.
There is no consensus on science, so it is not saying that there is a consensus and we need less science because everything is solid. We need more science. There was a letter signed by more than 300 scientists on biotech in Europe saying there was no consensus on the impact of GMO products on health.
The miracle solution is not to say at the last minute that we have already done enough scientific research and that everything is going well. Rather, the goal is to do more research to fully ensure that there is no impact on health.
As you say, it isn't just the impact of GMOs on health. Even if genetic modification had no impact, we know that GMO crops require a significant amount of pesticides and that, in scientific research, the impact of pesticides on health is well documented. There is a consensus on the matter, namely, that pesticides act negatively on plants and insects. Although there was a consensus from one day to the next that genetic modification has no impact, the fact that more pesticides are being used globally in GMO crops has an impact on the environment and on health.
