It's great that you've been developing pollution code too! I understand that this can be a difficult task, but despite the problems, you continued to work on it. I got so carried away that I even found ocean pollution essay examples and topics ideas, used https://studymoose.com/free-essays/ocean-pollution for that. It is this kind of effort and perseverance that helps us find innovative solutions to protect the environment. Keep it up!
