The glyphosate-based herbicide Roundup has been found to trigger the loss of biodiversity among phytoplankton communities in freshwater ponds. In their experiments, scientists found that while some populations developed resistance to the herbicide and were able to survive exposure at high levels, this came at a cost, with a 40 percent loss in biodiversity.


"The ubiquitous presence of glyphosate in the environment has sparked concerns over its potential health and ecotoxicological effects," Andrew Gonzalez, from Canada's McGill University, said.
