In the film of Dune, Paul Atreides scans a box of the Spice Melange with a hand held device, before eating a sample. Passing the device over the spice, and it finding no contamination the device intones ‘safe’ in a soft female voice.
This is all you need to stop the contamination of the food supply with GMO goods.
An iPhone app that connects to a database of all food products known to be safe could be used to inspect every barcode on products you buy, returning safe, or nothing.
If you buy a product that returns nothing, this means it is either safe or not in the database, or that it is a GMO contaminated product and you should not eat it.
It is important that the software works in this way, because it means that the developers will not be at risk of a lawsuit for a wrongly labeled product, placed in the database by mistake. All that is needed is a database of clean foods, not a database of all good foods AND bad foods.
There is a piece of software that works in this way, with a focus on books:
With this app, you can scan the cover of any book, or its barcode and the software will retrieve entries on Amazon and other sites for you to buy it.
There is no reason why an app that scans the barcodes of products and returns wether or not they are contaminated could not be written, very quickly, to address this problem. Creating this software would be a piece of cake.
It is clearly pointless to run to the State to ask it to, “protect our food”. In any case, it isn’t your food until you buy it, and you cannot rely on the State for protection from every possible harm, and neither should you. This is especially true when the protection you need can be had straight away and under your control, totally ethically, without force of any kind.
Clearly there are millions of people who do not want to consume GMO contaminated foods. All of these people either have iPhones or Droids in their pockets. The market is ripe for an app that can put these two together to stamp out GMO food once and for all, via the power of a complete boycott, mediated by the internet on portable devices.
