My point is that in terms of personal responsibility nothing comes remotely close to driving but a vanishingly small proportion of people are willing to consider this.
What I've read is that diet can do more, though of course it depends on what you currently eat and your current transportation.
Flying is much higher than driving.
A few decades ago we explained that personal responsibility isn’t the solution.
Please catch up. Why we’re having a conversation from the year 2000 now is beyond me.
I also suggest reviewing the “nuclear isn’t part of the solution. Besides it takes a decade” discussion.
