You sound like a climate change supporter and we know what fucking bull shit that is. I have read science studies that are not your view. One other thing, science has told many lies and is not an absolute. GMO food is bad also.
There are some studies here along with commentary about how Monsanto pays off national licensers and environmental groups in order to allow Roundup to be used in their countries.
If Roundup was completely safe, why pay off these gov't officials? Why does Monsanto try to disparage studies and scientists? Why does Monsanto try to hide their own studies which show it's dangerous?
