Sustainability needs realism to work

Someone at dinner tells you they've gone vegan, and you feel it immediately, that small flinch before you even decide to. Suddenly your own plate feels like it's being judged, even if nobody said a word. That's not really about food. That's what a binary does to a room, it turns a choice into a verdict, and it pushes people apart exactly when you need them moving the same direction.

I think that's the real problem with how sustainability gets talked about. Clean or dirty. Right or wrong. Acceptable or not. The world doesn't actually work in binaries, so a message built on them starts losing people the moment it meets real life.

Take an electric car. It gets sold as the clean choice, and in many ways it is a real step forward. But the dashboard is still largely petrochemical. The battery still comes from energy-intensive mining. The electricity charging it still often comes, at least partly, from fossil power. None of that makes the EV pointless. It just means we're not swapping one system for another overnight. We're reshaping something built over more than a century, one piece at a time.

The same is true of how we eat, move, and live. Transport, housing, food, these are the biggest parts of most people's footprint, and none of them get fixed by elimination. They get fixed by adjustment, repeated, over years.

Here's my own small version of that. I no longer eat meat during the week. On its own, it's a small thing, barely worth mentioning. But it's not disconnected from how I actually live, and I've kept it up because of that, not despite it. Multiply a small, sustainable adjustment like that across millions of people rather than a handful doing it perfectly, and the effect stops being small.

That's really the whole point. Progress was never going to come from perfect people making pure choices. It comes from realistic people making better ones, consistently, without needing to feel judged into doing it.
