What does the first quote offer as proof of being an environmentalist?

The speaker simply points to recycling as the basis for calling themselves an environmentalist, keeping the claim modest and grounded.

What does the second quote say about expertise?

It explicitly denies being an environmentalist, doctor, or nutritionist, distancing the speaker from any claim of specialized knowledge.

They take slightly different stances, one embracing a small environmentalist habit and the other rejecting the label along with other expert titles.

Both are modest and self-aware, avoiding grand claims and instead being honest about the limits of personal expertise or effort.

Anyone who tries to live sustainably without claiming to be an expert would likely relate to this down-to-earth pair of remarks.

These quotes weigh what it means to call oneself an environmentalist, from a simple habit like recycling to admitting a lack of formal expertise.

I'm an environmentalist; I recycle.

I'm not an environmentalist, or a doctor, or a nutritionist.
