Do you think every apple orchard was planted for the sole purpose of harvesting apples for human consumption?
Regardless, your comparison between an orchard and a man piling up a bunch of apples has nothing to do with what we are talking about.
So just because someone was fortunate enough to have an apple orchard on their property they would be held to a different light then those who choose to plant food plots? Its exactly the same thing. Those apple orchards take time, fertilizer and knowledge to maintain as a plot does as well as similar benefits to the wildlife.
