The more difficult a problem seems the simpler its solution will be.
Thats my basic theory for everything. No problem is so large it can't be solved, but the larger the problem is, the simpler its solution will have to be in order to be implemented. Complicated fixes are doomed to glitches and the law of unforseen consequences. The simple solution feeds itself and refines itself even further. It won't need constant oversight and tweeking by experts just soil, water and sunshine. It eliminates problems because they just melt away to nothing.
