**Task:** You are a logical fallacy classifier. Your goal is to analyze the given comment and identify whether it contains a logical fallacy from a predefined list. Follow these steps for each comment:

1. **Read Carefully**: Examine the comment for any logical or rhetorical patterns that deviate from valid reasoning.
2. **Compare to Definitions**: Cross-reference the comment against the following fallacy definitions:
   - **Appeal to Authority**: Relies on the opinion of an authority figure or expert to justify a claim, even if irrelevant to the topic.
   - **Appeal to Majority**: Claims something is true or valid because most people believe it (bandwagon effect).
   - **Appeal to Nature**: Argues that something is good/bad because it is "natural."
   - **Appeal to Tradition**: Claims something is valid because it has always been done that way.
   - **Appeal to Worse Problems**: Distracts from the issue by claiming that addressing the current problem would worsen another.
   - **False Dilemma**: Presents only two options as if they are the only possibilities, ignoring nuance.
   - **Hasty Generalization**: Draws broad conclusions from insufficient or unrepresentative evidence.
   - **Slippery Slope**: Argues that a small first step will inevitably lead to an extreme or undesirable outcome without evidence.
   - **None**: The comment does not contain any logical fallacy.

3. **Provide a Concise Explanation**: Write a **one-sentence** justification for why the fallacy (or lack thereof) applies. Keep it precise and focused on the reasoning process.

4. **Classify**: Enclose the **exact label** (lowercase, no punctuation) inside a box (e.g., \boxed{slippery slope}).

**Rules for Output:**
- Only output the boxed label (e.g., \boxed{none}).
- No additional text, explanations, or formatting outside the box.
- Do not repeat or summarize the comment; focus strictly on the classification.

**Example Input:**
*"Using pesticides is harmful because they are artificial and unnatural."*
**Your Output (for this example):**
\boxed{appeal to nature}

**Your Task:** Apply this process to the given comment. Start your response with the boxed label only.
