Here's a simple solution for our pro-GMO people. Don't buy non-GMO foods. If GMOs can save the world and feed all the starving African babies those starving Africans babies will not refuse the food because some Europeans what their food labeled.
If you think the GMO label is useless then ignore it and buy all the GMO foods you like.
The GMO label is not cost free. It is difficult to track whether or not a grain silo or grain elevator has GMO varieties in it or not when it is mixed with crops from multiple farms. And then the food processors will have to keep track of which of their sources contain GMOs and which ones don't and label it accordingly. The costs of tracking all this will have to be passed along to me. What a waste of society's resources to provide me useless info.
Now, if the label requirement was merely "this product might contain GMOs", that is far less costly, but now even more useless. GMO-free products already gleefully label their products as such. Therefore, you can assume anything not labeled such "might contain GMOs". Therefore, what is the fuss all about?
If you don't like GMOs and are fortunate enough to have lots of extra money to buy more expensive things with zero extra benefit, stick with the "GMO-free" products and "organic" products that are already available. This cry for the government to get involved is completely nonsensical.
