Look, there has never been any solid evidence at all that the most common herbicide (weed-killer) used in America — atrazine — actually harmed amphibians. On the other hand, atrazine has been estimated to have saved billions of dollars in increased corn crop yields over the many decades it’s been widely used in the corn-growing heartland.

However, he had always declined to share his experimental data, even when those data seemed, to outside objective researchers (including those at the EPA) to be contradictory or implausible.
