This Week in the Future, April 18-22, 2011 Baarbarian

We're not trying to be negative. We're just looking out for you when we tell you all the things you should think twice about consuming--whether it's leavened bread, human waste, or an excess of electronics. What you should do is read on--there's no other way to win this week's Baarbarian illustration on a t-shirt.

The rules: Follow us on Twitter (we're @PopSci) and retweet our This Week in the Future tweet. One of those lucky retweeters will be chosen to receive a custom t-shirt with this week's Baarbarian illustration on it, thus making the winner entirely too cool for their school, or place of business, or couch. (Those who would rather just buy the t-shirt can do that here.) The stories pictured therein:
