I would have preferred this substances to be water, not oil. Because water is better because oil pollutes is harmful air. That’s why using water is better than using oil. If we use water the air will not be polluted and it will help keep the sees the clean. Our environment and nature are not polluted. If it gets dirty living things and people die. Plants that live in nature also die. This situation adversely affects aquatic organisms. That’s why we should use water more than oil, plants, aquatic creatures, animals and people do not die.
