Milk

Sharon Deem, Saint Louis Zoo

Camels are known for their ability to travel long distances across the desert without water.

But they’re also becoming an increasingly important source of milk for people in drought-prone regions. That includes East African countries like Kenya, where camel numbers have skyrocketed over the past few decades.

But introducing camels — or any species — to a new region, could mean bringing in new diseases.

The St. Louis Zoo has been studying camel diseases in Kenya to help assess their risks.
