what environmental problem presents a major challenge for iowans today

One major environmental challenge facing Iowans today is water pollution from agricultural runoff. Fertilizers and pesticides used in farming can leach into waterways, contaminating drinking water sources and harming aquatic life. This pollution can also contribute to the Gulf of Mexico's "Dead Zone," an area of low oxygen caused by excess nutrients entering the water. Addressing this issue requires sustainable farming practices and better land management to reduce runoff and protect water quality.
