If you use Round up just dont breath it or get it on yourself. i used it until i got cancer (iam fine now, no problem) it made me think about all  the cancer all over the world, our life styles in the USA are not the same as a person in Nairobi and India etc. so cancer cannot always be a lifestyle problem like the DR. put on us. the only common denominator i saw was Round-Up and chemtrails. now i pull the poison oak myself and put bleach on the weeds. I didnt like thinking i was poisoning the animals anyways. but hey they spray all of our food with it. gross. buy organic if you can, i know it gets expensive.
