Thank you Karen F. for this additional information.
A report done for 38 Degrees said that "Glyphosate is only supposed to kill weeds, however if you look at its ecotoxicology profile, it is also moderately toxic to mammals, fish, aquatic invertebrates, aquatic crustaceans, algae, honeybees and earthworms."
For anyone wanting more information, there is an interesting article here:

and a scientific analysis of glyphosate here:
