Why would a farm choose to build their farm up stream from a factory?

• The water at the highest point of the river will have less of a chance to be effected by

  human activities, so it should be the cleanest.

• Farmers do not have a negative impact on the environment

• The factory is polluting the air so it does not matter where the farm is located.

• The farm should be placed upstream because pesticides from the farm will end

  up in the river, which is beneficial for the factories downstream.
