True, they're also producing some vastly expensive pending problems. Monsanto's "RoundUp Ready" genes have crosspollinated both Poa annua and Conyza canadensis, a grass and an astercae, two of the most promicuous families of aggressive weeds. In this habitat restorationist's view, this is a pending disaster, particularly for farmers and ranchers because plants in these families constitute some of their most pernicious weeds.
To deliberately destroy the usefulness of glyphosate when the patent runs out and transfer "RoundUp Ready" to your hot new and far more expensive patented herbicides (which is what I have always thought Monsanto was doing with "RoundUp Ready") is an actionable cause for compensation.
