<p>Pigs really are dirty--but only because humans make them that way. Hog farmers crowd the animals, dose them with antibiotics, and spray out their drug-tainted feces, wreaking havoc on fields, streams--and you. Pigs huddle atop grates that allow waste to drip through.</p>
<p>On many hog farms, the waste runs into a storage lagoon from which it is pumped and sprayed on surrounding fields.</p>
<p>In 1995 one such lagoon spilled into a nearby river, killing 10 million fish and contaminating drinking water. Last July North Carolina became the first state to ban building new lagoons on hog farms.</p>
<p>Storage lagoons take on an electric color from bacterial reaction to hog feces.</p>
<p>Such lagoons can cover up to 7.5 acres, albeit on a farmer's own property.</p>
<p>The problem: Overflow and sprayed waste can find their way into local wetlands, where fecal matter triggers algal blooms  that choke out other aquatic life.</p>
<p>Seen from about 700 feet up, this storage lagoon swirls with feces, afterbirth, pesticides, bacteria, and hormones. In the United States, hogs produce more than 119 million tons of waste a year.</p>
