**Key considerations when choosing a description:**

* **Blog audience:** Who are you writing for? A more educated audience might appreciate a more technical description.
* **Blog content:** How deep do your posts on pollution go? If you cover a lot of topics, a broader description is fine. If you focus on specific aspects, you can be more targeted.
* **SEO:** While these descriptions are more for human readers, using relevant keywords (like 環境, 生態, 健康, 等) can improve search engine optimization (SEO) slightly.
