"Switch to bio fuels that are carbon neutral and we have no problem"
I'm not sure you have a very good grasp of the basics of energy flows as in ecosystem thermodynamics.
Bio Fuels have very poor EROEI ratios, meaning you need more energy going in than you get out. Fossil fuels have the great advantage of having concentrated solar energy over millions of years before being cooked in the earth for another couple of milion They do have the disadvantage of being a finite resource..

Though Bio fuels still have their uses for niche application while fossil fuels long term are a dead end, that's our civilization's current dillema.
While solar energy probably will not power air cargo transport any time soon, wind and solar can certainly power high speed trains...
