Lake Victoria's wetlands, beaches in trouble from raw sewage and dumping

Two men load sacks of charcoal on a truck a few metres away next to the mouth of the heavily polluted river Wigwa, along Kisumu's lakefront.

A hippo slowly rises above the water and snorts angrily, probably to scare the men who have invaded their territory. Moments later, two other hippo heads rise above the water and join the snorting.
