The law of unintended consequences will prevail as it does with most attmempts of man intervening in complex eco systems. This will more than likely not be serendipitous, but more of a drawback.

We have caused famines messing with little things like this. Just my 2 cents. I think it is a noble idea, I find it hard to believe that alphabet Inc is in it for all the reasons they state, but I will have to take them at face value.

There are other ways, the reason you don't see them is because they more than likely require too much work, too much change or don't turn a profit.
