The use of GMOs is controversial. There is debate in the scientific community as to whether the consumption of GMO foods hurts people directly. But there is no denying that GMOs result in vastly more herbicide (such as Roundup, a top weed killer) being dumped on food crops, and that glyphosphate (the active ingredient in Roundup) probably causes cancer in the quantities used. Other Roundup ingredients are suspect as well. Those who oppose GMOs don't have the upper hand in Congress and so they ... seek to establish a uniform labeling system so that food producers clearly identify whether their products have GMOs or not. Labeling is very popular among American consumers: In multiple polls conducted over the years by many different firms, about 90 percent of Americans consistently support mandatory labeling. Mandatory labeling initiatives are in play in many states, and have passed in three (Maine, Vermont and Connecticut). But Big Ag is spending heavily to block these efforts. The House and Senate are listening to Big Ag rather than to American consumers. The House recently passed a bill that gives the appearance of supporting GMO disclosure while doing the opposite. The bill, H.R. 1599, carries a brilliantly deceptive name that would make George Orwell proud. Called the "Safe and Accurate Food Labeling Act of 2014" the bill would reinforce the current voluntary disclosure system but would prohibit individual states and counties from enacting more stringent legislation. The detractors have branded this bill the "DARK Act" as in "Deny Americans the Right to Know"."
