Overlapping dimensions.

My family has planted a small edible garden of fruit trees for the public, but the deer come and eat up the food before people can. Then the trees don't flourish because of it, so they can't produce more to sustain food for the deer and the people.

Ah, so they're the culprits of the gimmick.

Don't tell them that. Might cause someone to think for theirself.

Indeed they are. You can tell from where they are growing out of the tree.
