It is a logical leap, but more appropriately: Eating factory farm meat contributes to the cultural acceptance of such goods being produced in the way they are, that produces bacterial immunities to antibiotics due to the mass utilization of factory farmed meat. And: Driving gasoline powered automobile contributes to the cultural acceptance of such goods being produced using the engine technology they are, that emits greenhouse gases that cause global warming due to the mass utilization of gasoline powered vehicles. An individual won't have a significant impact on either, but if you aren't swayed (the guy reading this on HN) we are completely fucked, because the community here is supposed to be one of the more rational and long term considerate groups of people. To expect average joe burger flipper to stop eating meat and driving cars because of the long term macroscopic ramifications of their usage is hypocritical if we don't practice what we preach.
