This reliance upon, or even worship, of one species is a disaster waiting to happen. Permaculture would solve this, it strives to create multitude of relationships between many animal and plant species, and unorthodox accomodation to local circumstances /ecosystem. Then whole agriculture would not depend one single type of tree and is more resilient.

But the unorthodox part is probably where it breaks down, it's much easier for humans to follow "recognized" methods than observe and adapt.
