Slightly acidic

Attack of the Genetically Engineered Tomatoes, by Nicola Hamilton is an
easy read about a potentially difficult subject. Its facetious title might put
you off a clear and up-to-date exposition of what we know about genetics. Since
there is still a way to go, genetic engineering of plants and animals is a path
to tread warily. It offers a sober and fair survey of prospects and dangers.
Illustrations, though amateurish, lighten the task of understanding. Published
