Kids at a primary school in Cornwall have got involved in a campaign to try and stop a chemical thought to be killing seabirds from being dumped at sea.
Have you or your school ever got involved in a campaign?
Perhaps your class has made posters to try and save animals from extinction or to help the environment.
Or maybe it's something more local that you've got involved in like trying to stop dog mess.
Whatever it is, let the Newsround team know - and we will see if we can report on the story. Find out how to get in touch here.
