For things like air travel carbon neutral fuels are likely a better short to medium term solution (in the long term we can posit magical high density batteries).
However, if we are going down the path of actually trying to clean up the earth we should take a really long term view and remove all heavy polluting and heavy land use off planet. There is plenty of mass out there to do manufacturing, farming etc. Let's make earth into a garden planet giant park.
