环保 (huán bǎo) is a noun meaning 'environmental protection' — the practice of preserving natural resources, reducing pollution, and safeguarding ecosystems for current and future generations. The first character 环 (huán) means 'circle' or 'environment' (as in 环境 huánjìng, 'environment'), while 保 (bǎo) means 'to protect' or 'to preserve'. Together, they form a compact, widely used term that conveys active care for the natural world.

This word appears frequently in public discourse, government policy, education, and everyday life — from eco-friendly product labels to school campaigns and news reports on climate action. It’s often used as a noun modifier (e.g., 环保意识 'environmental awareness') or in compound nouns like 环保组织 ('environmental NGO'). While not limited to animals, it strongly overlaps with animal conservation efforts, since protecting habitats and biodiversity is central to environmental protection.
