> all the pollutants, heavy metals, and other chemicals that are in the X liter of diesel a farmer burns per yet, ends up on, and in the crops. It's really not that much. A combine harvester uses about 15 gallons / hour of fuel and harvests ~450,000 pounds of corn per hour ie more than a lifetimes supply of food. Various other equipment gets used but it's all trivial in comparison to what's directly sprayed on crops. Meanwhile your directly exposed to all the car fumes around you on a daily basis. Also, tulips aren't a food crop.
