Modern zoos have evolved from simply housing animals to playing an essential role in conservation efforts worldwide. Through advancements in science, education, and ethical practices, zoos now serve as conservation centers where animal welfare and species preservation are prioritized. With natural habitats threatened, zoos help ensure survival by protecting and breeding animals that would otherwise face extinction. Many zoos participate in Species Survival Plans (SSPs), which are carefully managed programs for endangered animals, focusing on genetic diversity and, when possible, releasing animals back into the wild.

Zoos also work on rewilding projects, where animals are reintroduced into protected areas to restore natural ecosystems. These projects are supported by extensive research on habitat requirements and social dynamics of the species. For example, reintroducing wolves to controlled environments has shown how animals can positively impact ecological balance. Additionally, zoos partner with universities and international organizations to conduct research that benefits both captive and wild populations. By promoting awareness, engaging the public, and participating in field projects, zoos have transformed into vital allies in the fight against species extinction and environmental degradation.
