I'd like to suggest the spawn rate of tree seeds to be lowered, or some additional use for them created. Perhaps they can be fed to a 'Piglet', who also needs water (some higher amount of each) to turn into a 'Pig', after which you can slaughter them at a 'Butcher Block', using a 'Cleaver', resulting in 'Bacon', which the Folk will love (let's face it, who doesn't love bacon?)
