“Americans waste a staggering amount of food. Instead of letting it rot and wreck the environment, some entrepreneurs want to put it to work feeding insects, and see the potential to revolutionize how we feed some of the livestock that provide us our meat. Phil Taylor’s enthusiasm for insects is infectious. The University of Colorado Boulder research ecologist beams as he weaves through a small greenhouse in rural Boulder County, Colorado.
