How Far Can We Get Without Flying?

[longship]

5. Unrealistic. The world economy and society would utterly collapse without airplanes.

What a silly argument.

The solution is to make those energy sources which we can, renewable. Flying will likely always require some kind of high energy fuel and one is not likely to change that anytime soon.

But we can do a lot in other areas. A whole lot.

We do what we can do. And we all know we've not done enough. But one dude not flying is not going to help much, as much as I sympathize with his sentiments. His solution is a non-starter. What does he want to do? Ground all airplanes? Good luck with that.
