The ice bucket challenge isn't a waste of water, and this chart proves it

Vox.com tries to pour water on one of my complaints:

I've seen a few different people criticize the trend for wasting perfectly good, clean water. That may be true, but when you look at the amount of water wasted in the context of the staggeringly huge amounts of water we use to produce food — especially animal products — the ice bucket challenge is truly a drop in the bucket (sorry).

While the amount of water used to produce food is suprising in most of the examples, I still think this is a poor comparison. Comparing an internet meme to something that is a necessary component to producing life sustaining food seems kind of silly.
