Sure, i agree on that, but we would also need to remove subsidy to have a free market work. Till then people will have intensive to buy whatever the subsidy is for.. Education is lacking or not reaching the masses. This is obvious to me when I see my " high educated" friends still skipping the organic food and going for the bargains.
So what to do when your neighbors uses it all around their house or farm and are not willing to change when you point out the dangers or how to use it better?
Before we reach a true free market without influence of all the power of Monsanto/Bayer, what to do when someone next door can poison your food and water?
