Shimon Steinberg looks at the difference between pests and bugs -- and makes the case for using good bugs to fight bad bugs, avoiding chemicals in our quest for perfect produce.

Shimon Steinberg is chief scientist at Bio-Bee, a world leader in mass production of the world's best natural, biological control agents: bugs. (Beneficial bugs are replacing the use of chemical sprays in greenhouse vegetables and open field crops, producing pesticide-free food and eliminating hazardous exposure of millions of workers in third world countries.) These insects are shipped worldwide, where they go to work protecting thousands of hectares of greenhouses and open fields, in vegetables, field crops, fruit trees, ornamental plants and more.
