See this column regarding Walmart going organic and its critics. Especially the last paragraph printed below.
“The perfect should not be allowed to become the enemy of
the good. In an ideal world, local farmers would produce delicious
foods grown without any harm to the environment at prices we could all
afford while simultaneously making an excellent living. The livestock
would all live happy lives, singing their little animal songs, dying a
natural death and yet remaining tender and tasty. We would then get
together and cook them over our campfires which produce no smoke, sing
our little campsongs, and eat our meals in perfect harmony.
That world, unfortunately, does not exist.”
