I also cringe at the promotion of genetic engineering being presented as a solution. Science about that has been largely funded and promoted by the very corporations and interests that have caused the problem in the first place by mis-leading the all too willing masses, with mind control, into choosing to support thing that are detrimental to everyone.
These same interests have led many to believe we are overpopluated when the initial issue, upon firther inspection, seems also to be intentional "mismanagement" by those same interests for the purpose of controling resources and populations so they could gain control of the world. They create starvation and so forth in order to hand out the solutions that tend to lead us to having to depend upon them even more... which is how we all got into this situation in the first place. Looking for another (externally searching) to be our savior when we are the solution we have been looking for the whole time.
Our bodies view genetically engineered substances as foriegn invaders which causes inflammation, hindering our immune systems. Our bodies need the things that have evolved naturally in order to remain healthy. Anything else only provides a temporary fix that usually makes the problem worse in the long run. Using Fungi and organically occuring microbes might be helpful, as that is how nature works. But most people don't even realize how even a simple thing as healthy living soil works, because we've been mislead to suit the corporate agenda. With a healthy environment, food would be free and grow everwhere. Healthy food= healthier people on so many levels that the entire word would be a lot different. These companies don't profit from that.
Most of all we need to change our own behaviors. The answers we need are within each of us. IMHO.
