Cheerios' recent campaign to give away flower seeds was both wildly popular and, no surprise, controversial.
General Mills, maker of the O-shaped oat cereal, said it initially planned to dole out 100 million wildflower seeds to customers who requested them.
The goal? Boost the ranks of North America's imperiled bees. Cheerios instead gave away 1.5 billion seeds, depleting its entire stockpile.
