Permaculture is soil- and insect-friendly and can be productive and resilient, but it requires more manual labor and setting up a permaculture system takes a lot of knowledge and I think it takes years before it is producing competitively, depending on the soil conditions.

If we ban synthetic fertilizers (an more importantly herbicides/pesticides) abruptly before having established organic methods at scale, that will most likely cause food insecurity like it did in Sri Lanka.

Slowly phasing them out to a level that is not killing us in the long run seems more sensible to me.

I was thinking of banning them for residential use and then re-evaluating their use in commercial agriculture industries. There's no reason that I can think of that they should be used in residential applications. All they do is keep grass artificially green and destroy soil health.
