What about the bees?

Abstract:

The health effects of a Roundup-tolerant genetically modified maize (from
11% in the diet), cultivated with or without Roundup, and Roundup alone
(from 0.1 ppb in water), were studied 2 years in rats. In females, all
treated groups died 2-3 times more than controls, and more rapidly. This
difference was visible in 3 male groups fed GMOs. All results were hormone
and sex dependent, and the pathological profiles were comparable. Females
developed large mammary tumors almost always more often than and before
controls, the pituitary was the second most disabled organ; the sex hormonal
balance was modified by GMO and Roundup treatments. In treated males, liver
congestions and necrosis were 2.5-5.5 times higher. This pathology was
confirmed by optic and transmission electron microscopy. Marked and severe
kidney nephropathies were also generally 1.3-2.3 greater. Males presented 4
times more large palpable tumors than controls which occurred up to 600 days
earlier. Biochemistry data confirmed very significant kidney chronic
deficiencies; for all treatments and both sexes, 76% of the altered
parameters were kidney related. These results can be explained by the non
linear endocrine-disrupting effects of Roundup, but also by the over
expression of the transgene in the GMO and its metabolic consequences.
