Conservation biologists Craig Jackson, Kristine Ulvund, Kang Nian Jap and veterinarian Marianne W. Furnes trap Arctic fox pups to perform a medical check-up, at the Arctic Fox Captive Breeding Station run by Norwegian Institute for Nature Research (NINA) near Oppdal, Norway, July 26, 2023. Climate change and habitat loss push thousands of the world’s species to the edge of survival, disrupting food chains and leaving some animals to starve; and while some scientists say it’s inevitable that we’ll need more feeding programs to prevent extinctions, others question whether it makes sense to support animals in landscapes that can no longer sustain them. “If the food is not there for them, what do you do?” said Jackson.
