It's definitely much much better to eat organic food whenever possible. Limited availability and having no money can get in the way though! I love organic stuff, such a massive difference between real plants and bloated chemical crap. Although, bringing the difficulty of veganism a bit farther, it has to be pointed out that some organic growers use ground fish and dried blood as fertiliser, and there's rarely any way of knowing if your food has been grown like this. And as well as that, personally I'm not the biggest fan of the capitalist/exchange economy way of trading, or burning petrochemical fuel for transport. Best grow or forage yer own.
