Zones that Buffer Buffer zones protect ecologically sustainable farms from toxic chemicals in neighboring fields. Pesticides, herbicides, and pollen from genetically modified plants can be carried onto fields by the wind. Trees and other foliage planted in buffer zones minimize the risk of contamination and cross-pollination. Perhaps one day these zones will no longer be necessary, when sustainable agriculture is practiced by all farmers on all fields. | |
