A recent study from Israel highlights the critical role trees play in safeguarding rivers from agricultural pollution. Researchers found that streams in farming regions have suffered significant water quality degradation due to runoff from exposed soil and inefficient drainage systems. The presence of trees along riverbanks helps filter out pollutants, supports healthier ecosystems, and improves the overall function of waterways. The findings suggest that planting and maintaining trees near rivers could be a key strategy for restoring and protecting these vital natural resources.
