(8) At present such a custom is very rare owing the chemical pollution of sewage continuously increasing; but in some countries it is still in use, and is our opinion and experience that organic waste material must be reused as fertilizer of land, more and more devoid of humus and subject to erosion of winds and waters.
(9) "Organic" or "organically grown" foods are commonly represented as "food grown without pesticides; grown without artificial fertilizers; grown in soil whose humus content is increased by the additions of organic matter; grown in soil whose mineral content is increased with applications of natural mineral fertilizers; has not been treated with preservatives, hormones, antibiotics etc."
