First, well done for taking it seriously and doing your bit.

The point of the post (I think) is simply to illustrate that certain actions are much, much more important than others. Anecdotally, there are still plenty of people out there who believe that, say, turning off a couple of (low-energy) lights, or “recycling” a plastic bag, are somehow major good deeds that allow them to kick their feet up and celebrate with a steak. There’s still way too much ignorance about all this, IMO.

In reality (as you seem to understand), some gestures are far more important than others. Ditching red meat (and dairy) really is a big deal. Everyone who claims to care about this problem should at least consider doing it.
