Advocacy is when someone speaks or acts on behalf of someone else. For example, if you care about helping people who don't have enough food, you can be an advocate for them. You can write letters to decision makers like your elected officials (like senators and mayors) or even give speeches. All of these things can show that you are standing up for people who don't have enough food or don't have the same rights as you do. You can also help people by donating money or volunteering at organizations that fight for people's rights.
