')So we can't just look at the land in terms of what it can give us humans, but what we must share with all other creatures. This means our food plants also will be eaten by a certain number of insects, varmints, etc. If we eliminate these critters, we aren't fostering an entire, functioning ecosystem, which is the goal of permaculture. Native plants must also be given a place. So remember, if you're talking permaculture, you're talking about not just a Garden Planet for humans, but for everyone else as well.
Exactly! The essence of natural farming is minimal interference with natural processes. There will allways be critters etc. to eat the plants that we also eat, but in a naturally balanced system there will be other critters to eat those critters to keep their numbers at a level where we too have enough food left to eat. Main principle: if there is a problem, don't try to solve it by taking action. Just stop doing what causes the problem.

')If we think about the carrying capacity in terms of allowing room for all ecosystems to function fully, it's easy to see that the human carrying capacity might be much lower than if we believed only humans could live on the planet. The damage and extinctions we see now from 6.7 billion humans might be due to the way we live, but it may also be in large part a result of turning all that lost biomass into human mass. No matter how we live, if we turn too much biomass into human mass, we have severely impacted the functioning of the biosphere, which depends on all or most of its parts. We simply do not know at present how many parts can be removed without the entire system failing. It would probably be more prudent to err on the side of caution and retain as many parts as possible in the biosphere, for our own survival as a species.
I wonder, what was the biomass of dinosaurs, how much other biomass was turned into dinosaur mass daily? The effect of dinosaur influence of was however not loss of other biomass but trees growing into giant trees with HUGE biomass so tall that even tallest dinosaur with longest neck could not eat... until dinosaurs changed into birds, of course.
