**When Choosing:**

* **Consider your audience:** Who are you writing for? Are they already familiar with the concept?
* **Context matters:** Where will this description appear? A tag cloud needs it to be brief. A longer post might benefit from more detail.
* **Focus on the benefits:** Highlight why people would be interested in learning about sustainable eating.
* **Use clear and concise language.** Avoid overly complex vocabulary.

I recommend either Option 1 or Option 2 if you want concise and clear tags. Option 4 would be the best on the post itself if you want to drive engagement.
