ENVIRONMENTAL CONSIDERATIONS
Persistent and volatile pollutants – including certain pesticides, industrial chemicals and heavy metals – evaporate out of the soil in warmer countries where they are still used, and travel in the atmosphere toward cooler areas, condensing out again when the temperature drops. The process, repeated in "hops", can carry them thousands of kilometres in a matter of days.
- Wind can carry pesticides away
- Only ~90% of pesticides reach the ground, the others are carried away
- Animals can carry pesticides through ingested plants to other areas and disperse it in their waste
