"Excerpt: Several past studies have suggested a link between
herbicides commonly used in farming and sexual abnormalities in
tadpoles and frogs. Such deformities may be responsible for declines
in frogs documented in areas affected by agricultural contaminants,
such as Sierra Nevada, Calif., McCoy said. Amphibians are declining
worldwide and agricultural chemicals are considered to be one likely
cause, she said. Others include pathogenic infections and habitat
loss."
Amphibians also don't do too well if there is too much ultra Violet light.
