| Blue Food |
In the immortal words of George Carlin, “Why is there no
blue food? “ According to The
Straight Dope, it’s because leaves are green. If they were orange, we’d
have plenty of blue fruits and vegetables. It seems that Mother Nature wants to
set up the maximum color contrast between foliage and flowers or fruits. This
contrast helps animals find flowers to pollinate and fruits to eat. Plants
actually benefit when animals eat their fruits. Since plants can’t move much,
they rely on animals to transport seeds and "plant" them in other locations.
