The honey is your first source. Make sure your firewood and dry grass is 
gathered and started before attempting this. The next step to get food is
to repair the lift located next to the fruit tree by the water. You must 
advance your Restoration one level in the Tech department. Make sure to 
have at least one or two villagers in Researching to earn those Tech points.
After advancing one Restoration level you need three builders at once to fix
the lift. After it is fixed, while it rains quickly drag a villager onto the
flat end of the lift to stand on it. It will lift them up and they will knock
down a fruit seed. You can use it to plant another fruit tree. 
You can have a total of three fruit trees.
