The LD-50 is a very limited statistic, and it can be used in misleading ways. Round-up is very toxic to frogs, tadpoles, and other amphibians.

No link here (newbee) - but plenty of info on documented environmental problems from roundup can be found by searching.

They've removed the big 'Biodegradable' from the bottom of their label for a reason.
