The Helsinki Committee for Human Rights is a group of people who work together to make sure that everyone is being treated fairly and kindly. When someone's rights are being taken away or they are not being treated with respect, the Helsinki Committee steps in to help. They keep watch over different countries to make sure that people are not being hurt or treated badly.
The Helsinki Committee also talks to leaders of countries to remind them that everyone should be treated with respect, and they suggest ways that things can be changed to make sure that everyone's rights are protected. They also help people who have had their human rights taken away like the right to speak freely or the right to vote, to get their rights back.
So, just like how a group of grown-ups might help make sure that everyone is playing nicely at a playground, the Helsinki Committee for Human Rights helps make sure that everyone everywhere is being treated kindly and respectfully.
