Permaculture: What are the advantages of Diversity in all systems?
Answer:
BIO DIVERSITY
bio diversity is important every where because it creates balanced eco systems.
for example a tree requires certain chemicals and also discards certain chemicals.
too many of one specie demands to much of the soil and exhausts the soil of the chemicals it requieres and so saturates the soil with its secretions and in this way upsets the balance,
Too much of the same chemical output the soil gets poluted,

Natures law of HARMONY or EQUILIBRIUM
In Nature everthing and every one is welcome but something in excess is called a plague and Nature responds with preditors or sickness (which are preditors at bacterial levels)
Specific plants and trees have specific insects and animals that are associated with them
With bio diversity of species of flora ,there is a a variety of insects ,with a variety of species(like birds) who eat them ,
And a subsequent variety of preditors following,creating a chain of biological events of great variety which enhances the quality of Nature instead of diminishing it .
So there is no excess of any thing in particular just a multitude of life.bio diversity
A bio diverse forest consisting of many different species is the best for all situations,
Therefore bio diverse systems are always the healthiest
this is why we hardy ever see sickness or plagues in nature or if we do never for long.
Many plagues are caused by humans,who have destroyed links and so the natural balance is gone.
A sign of an eco system in trouble, is plagues of caterpillars,
which can happen if all the kids kill all the birds with their catapults.
Just think that whatever is killed ,its food is still walking around,
or if the food is destroyed the ones that depend on that are gone ,
As happened when they sprayed the mosquito´s on the banks of the Danube ,the forests became empty of life,because the basic links in the food chain were gone
Bio diversity of Flora and Fauna is interelated ,and so is fragile and easy to offset
And the bottom line is that Variety is the spice of life and its health
Permaculture seeks to follow these Natural principles ,when planting ,to have the least negative effects and so that little counter action is needed

A disadvantage for comercial farming would be that instead of having huge quantities of one crop,we end up with a great variety,which is not viable in terms of comerce ,with harvesting ,packaging and marketing
But then Permaculture is not aimed at comercial farming it means to make it in great parts obsolete
by having a great number of small growers who plant for the quality of their lives ,not for the market
and to encourage local trading or interchange
However many principles of Permaculture can be applied to comercial farming
