Make it square, that would be a big change. The world would spin like a dice (which would look cool). I wonder how a ship would handle the 90 degree corners (autos could handle it fine).
What about redecorating? Maybe contemporary would be a good way to go. Change all the mountains so they had only right angles. There could be a contest to find the best design.
Rearrange the Continents (similar to rearranging your bedroom). Fung Shui would be a good guideline for this (some of the Continents look out of place). While we’re at it, separating the ones that don’t get along would be good.
A new paint job might do the trick. A custom earth tone flame scheme would be totally cool. This could attract attention from passing aliens (maybe they would stay longer or at least talk to someone, instead of just lurking around).
How about making it flat, like it was before they made round? This could help MPG world wide. Giants could use it for a Frisbee (OK, so flat is not a good idea).
Everybody has their own idea.
Sustainability is the change I would like.
