Death of a Butterfly

Summer 2001

One early morning last spring, my half-asleep eyes caught the opening lines of a letter in my local newspaper.

"I am a farmer. I knew that since I was 5. I grow crops. The land I farm also grows butterflies, birds, earthworms and wildflowers, or at least I think it is supposed to. Right now I am having trouble figuring out what kind of farmer I am or should be. This question is not just for me but for you. I am concerned that there is no room for bluebirds and butterflies in big, precision, genetically-modified agriculture."

The letter, from a family farmer named Michael Klingelhutz, went on to describe one of the many destructive aspects of industrial biotechnological agriculture: the destruction of vital habitat for wildlife.

He wrote about the importance of milkweed as the sole habitat for monarch butterfly caterpillars and about how, before the advent of new biotech soybean and corn crops, he had "raised a good crop of monarchs" as part of his farming. But in the late 1990s, "Roundup Ready genetically engineered soybeans became widely available. Roundup herbicide kills everything green except the soybeans with the genetic alteration."

The farmer eventually realized that more than just his milkweeds had disappeared - so had the monarchs.
"My milkweeds are gone. My neighbor's milkweeds are gone. Farmers using Roundup Ready genetics in soybeans, cotton, corn and sugar beets are eradicating milkweed from their fields nationwide, forcing the monarch butterflies to lay their eggs on milkweed in field borders and ditches."

The purpose of most biotechnology in crop farming is to kill all plants and insects except the single, genetically-engineered crop the biotechnology is designed to protect. The two major biotech crops in use today, accounting for 90 percent of genetically engineered acres in the United States, are Roundup Ready crops (like soybeans), mentioned in farmer Klingelhutz's letter, and Bt crops, short for Bacillus thuringiensis, like Bt corn.

Monsanto Corporation's Roundup Ready crops have been manipulated to contain a special gene that makes them immune to damage from very high doses of Monsanto's Roundup herbicide. Roundup kills essentially every green thing in sight except crops injected with the special gene.
