Okay, the user wants me to translate "environmental scientists" into Japanese. Let me check the rules again. The first rule says to translate all content into Japanese. The second rule states that if the content is already in Japanese, leave it as is. The third rule is to provide only the translation without any explanations.
So, "environmental scientists" is in English, so I need to translate it. The correct Japanese term for environmental scientists would be "環境科学者" (kankyō kagakusha). Let me confirm that. "環境" is environment, "科学" is science, and "者" denotes a person engaged in a profession. Yes, that seems right. I should make sure there's no alternative term, but I think that's the standard translation. No need to add anything else. Just output the translation.
