Roundup Damages Earthworms and Soil Biota, Contributes to Nutrient Pollution

(Beyond Pesticides, August 17, 2015) A study published in Scientific Reports has found that glyphosate, the controversial and toxic active ingredient in Roundup, reduces activity and reproduction in two species of earthworms and increases soil nutrient concentrations to dangerous levels. Earthworms are excellent indicators of soil health, and provide vitally important ecosystem services by aerating the soil, cycling nutrients, and increasing soil fertility and microbial activity. The findings are especially alarming because this herbicide has been used globally for decades, and its use has grown exponentially. Earlier this spring, the WHO’s International Agency for Research on Cancer (IARC) classified glyphosate as Group 2a “probable” human carcinogen based on sufficient evidence of carcinogenicity in laboratory animals.
