With that attitude we can just go back to the caves. Big-anything is what makes our society and level of population work, without Big-Ag we couldn't feed everyone. Without Big-Trans we couldn't distribute the food. Without Big-Trade, you would have to inefficiently buy from 20 small shops selling one item each. Without Big-Industry, your kitchen implements would be a pot and a kettle above the fireplace.

Rapeseed oil maybe isn't a perfect solution. But whining about everything that makes headway just because it isn't perfect yet also holds us back.
