@Mongo: you got some great organic farms and Permaculture farms down under. So you should be able to taste some Biodiversity first hand (or first taste bud?) if you look around a bit. Permaculture was invented in Australia! There are also a lot of CSA-Farms = Farms that live by "Customers" "Subscribing" to their Product near the big cities.
Permaculture is all about Biodiversity in Agricuture, building deep soils, finding companion plants and animals that protect each other to save on Agro-Chemistry and create nutricious food.
I love food photography, but I am not good on the business side (yet), so I fight to stay alive, although I got great product.
