Slogan slogan is not well chosen.

"Advocate an environmentally friendly, healthy and fashionable life." There is nothing wrong with this sentence grammatically, but from a rhetorical point of view, it cannot be regarded as a dual sentence. But as a slogan, it is still possible.

The friend who asked the question asked, "The word' advocacy' in this sentence should be a verb, but can the word' health' behind it be used as a verb?" This meaning is obviously to use antithetical sentences. But "advocating" is a verb-object phrase because it is followed by an object. But "health" is an adjective, and the word behind it is not an object, so the structures of the two sentences are different, so they cannot form duality.

Although it is not an antithetical sentence, there is nothing wrong with the grammar, the content is appropriate, and the meaning is incomplete after it is changed (for example, changing it to "pursuing healthy life" or "pursuing fashionable life" will reduce the original connotation), so it is ok to use it as a slogan.
