Human beings are omnivores by nature, which means they can eat plants and meat and seeds and anything else they deem edible. Once the species figured out how to hunt successfully, it sometimes caused the extinction, or near-extinction, of other animals. In an effort to preserve biodiversity, some of these animals have been given protected status and have reestablished themselves. But this protection often means they are isolated from their natural predators and sometimes their natural predators are also threatened species, such as wolves. Human wildlife management is often a poor substitute for natural cycles. Joann Brennan calls this series of photographs Managing Eden, a title that suggests a bit of overconfidence on our part. “Our impact on nature,” the artist writes, “has made our touch essential to the lives of the animals we have imperiled.”
