Last April, the Cincinnati Zoo started growing some of the food it needs to feed its animals. Less than a mile from the elephant enclosures and manatee displays, it set up two storage containers equipped with hydroponic systems to cultivate lettuce and kale. Since then, the zoo has grown more than 8,000 pounds of produce in Avondale — enough to supply the giraffe feeding program.
The hydroponics system means the lettuce and kale don't grow in soil. Instead, they get nutrients from water and light from red and blue bulbs in the storage container.
Sustainability Project Manager Megan O'Keefe says the zoo still ships food in, but growing on-site is helping it be more resilient.
"We're dipping our toe in the water because there has been supply chain issues, especially with climate change — we're experiencing more droughts on these farms that we get our lettuce from in California, in the Southwest," O'Keefe said.
