In many cases the wrong fields are sprayed, resulting in not only a total loss of the farmer's crop- but the loss of that field altogether as nothing will grow where the herbicide has been sprayed.[3] Though official documentation of the health effects of glyphosate spraying in Colombia are virtually non-existent, neighbouring Ecuador has conducted studies to determine the cause of mysterious illnesses amongst people living along the border of Colombia and has since demanded that no aerial sprayings occur within 10 km of the border because of the damages caused to the people, animals and environment in that area.[3]
