Smug? Trapdoor, is not smug also applicable to your attitude? You are basically saying that you have privileged information that asserts that environmental issues are non-issues. Therefore, you don't have to take them seriously. You wear your "non-green" choices as ....smugly...... as a lecturing greenie.
I agree that the word and wording of "green" has already become wearisome. And I agree that the trendiness has already worn itself out. But the issues are very real and the consequences are too. Use a little logic: 6+ billion people on the planet using ever more technology to expand their personal sphere of impact is not sustainable. Read Collapse, by Jared Diamond for an authoritative, thoughtful and thoroughly gripping tale of human-caused collapses of entire ecosystems and the resulting collapse of societies that depended on them. It may influence that smug sense that nothing is wrong.
