Such laws exist for animals, too. They have the fast effect, that within a few reproduction cycles after the introduction of the law, the agriculture of a whole country (or like in the case of the EU a whole super-country) concentrates on the production of species with some defined positive characteristics, predominantly yield.

The negative effects are, that the selected characteristics not necessarily are what is good for humans, i.e. taste and nutritional values.

And it leads to genetic impoverishment.

The positive effects dominate only some decades. We are now in a phase, where the negative effects begin to get dominant. It will cost a lot of effort and money to alter course.
