Place it as the punchline after a shot of wasteful behaviour, such as a pile of packaging or a running tap, then follow it with Bruh. If the scene needs a reaction first, open with Oh My God Bro Oh Hell Nah and let this line close the joke.

This is a short spoken clip, about three and a half seconds long, built around a single voice declaring 'I'm an environmentalist' with confident emphasis. The delivery makes it feel playful and a little self-important, the kind of line that lands as a joke when someone is acting greener than they really are. It works best as a quick, knowing reaction rather than a serious statement.
