Endangered species are those at risk of extinction, meaning there are so few left that a species could disappear altogether. Species become endangered mainly due to habitat loss and fragmentation caused by human population expansion, which requires additional land for settlement, agriculture, and infrastructure. Hunting and poaching have also driven many animal species to dangerously low population levels. Conservation efforts aim to protect biodiversity by preserving existing habitats, restoring degraded areas, and sustaining species populations. Individuals can help endangered species by choosing sustainable products, recycling, volunteering with conservation organizations, and reducing their environmental impact.
