A "Guardian" is someone or something that protects or watches over others. This can refer to a person, like a parent or a legal guardian, who looks after a child’s well-being and makes important decisions for them. Guardians can also be found in stories, like a superhero who defends a city from danger, ensuring safety and security for everyone. In a broader sense, the term "Guardian" can also relate to organizations or systems that aim to safeguard the environment or human rights. For example, environmental groups act as guardians of nature, working to preserve ecosystems and promote sustainability for future generations.
