The principle should be to interfere with ecosystems as little as possible. The introduction of invasive species should therefore be minimized as much as possible. In nature, species invade adjacent systems and bring about change that way. But mankind is facilitating the introduction of species halfway around the world in ways that have no natural precedent.
Industrial monoculture uses a huge amount of resources and energy for the amount of food grown, largely in the form of synthetic fertilizers and pesticides. Enormous amounts of waste are likewise generated which further degrade the system. In those respects, industrial agriculture is horribly inefficient. The only area where industrial monoculture is more efficient than organic permaculture is that its financially cheap, predominantly because it displaces human labor.
Human labour is a lot more expensive than you seem to think. It is not just expensive in terms of wages, but also in terms of the various resources needed to support it. If we ran all our current farms on human labour then one of two things would need to be the case:
1. They would have to be extremely poor, as is the case for most subsistence farmers.
2. They would use many times the energy and other resources that city dwellers do. I am not talking about 10% more, I am talking about 10 times more.
I think you misunderstand what I mean by mimicking nature. By that I mean mimicking the workings of natural systems whereby waste if eliminated by repurposing it as energy for other processes.
That's hardly 'mimicking nature'. Only someone with religious delusions would think that nature somehow plans everything out so that waste is re-purposed. Thats simply not how it works. If waste is useful, some life form uses it, if it is not useful, it remains waste. In some cases this waste can be devastating - see red tides for an example. I could go on all day listing natural systems where waste is not re-purposed. This is the whole problem with making nature into a religion, you start to believe things about it that simply are not true - which leads to faulty decision making.
