A more thorough explanation:

Advocacy is the work of supporting a cause or proposal. It involves actively pleading for something you believe in.

For example, a group of people might advocate for better healthcare for everyone. They might organize rallies, write letters to politicians, and speak out in public to raise awareness about the issue.

Another example of advocacy is when a lawyer advocates for their client in court. They argue on behalf of their client to try to get the best possible outcome for them.

Advocacy is important because it helps bring attention to important issues and can lead to positive change.
