Organic Farming and Pollution |
||||||
 |
||||||
|
||||||
| Chemical fertilizers and pesticides applied to crops often leach into the soil and are carried by rain to rivers, contributing to water pollution, one of the most critical environmental problems of the 20th century. Organic farmers minimize water pollution by using non-toxic fertilizers and pesticides. | ||||||
