Which logical fallacy is used in the text?
Our family will never eat genetically modified food. It's an abomination created by arrogant human tinkering.

 - false causation: the assumption that because two things happened together, one caused the other
 - hasty generalization: a broad claim based on too few observations
 - appeal to nature: the assumption that natural things are always good
The text argues that genetically modified food is bad because it's not natural. However, something isn't necessarily bad simply because it's engineered. This illustrates a type of logical fallacy known as an appeal to nature.
