Having regard to the great benefits of these medicines, there is a need for that science considers more faithful the risks that they have on the environment, "explained Kathryn Arnold, University of York."Given that the populations of many species that live in environments altered by man are decreasing for reasons we can't explain it completely, we believe that it is time to explore the emerging challenges," continued.
