Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history. Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, where the controversial practice of culling healthy animals has sparked global debate. She also visits cutting-edge conservation projects and talks to leading scientists to examine whether zoos truly contribute to species preservation or if they are outdated institutions. The documentary delves into the ethical dilemmas of captivity, the psychological impact on animals, and the potential alternatives to traditional zoos, such as wildlife sanctuaries and habitat restoration. With insights from animal behaviorists, conservationists, and zoo advocates, the film challenges viewers to reconsider the role of zoos in the 21st century. Are zoos vital for education and conservation, or do they prioritize entertainment over animal welfare? This thought-provoking episode of Horizon confronts these difficult questions, leaving audiences to ponder the future of zoos in an era of rapidly evolving scientific understanding.
