[x] Earth ponies built Equestria. They invented the farming communities that colonized the land. And then they invented concrete when they decided they needed the proper soil in which they could plant buildings. Ponyville will always be an earth pony town, but it is time for it to embrace its future form. (Ponyville will begin to grow quickly, and many more ponies will benefit from it.)
[X] Earth ponies do not rush things. They do not make plants grow faster, but instead they care for it until it decides to flourish on its own. Ponyville is cared for, and it is flourishing at its own pace. There is no need to change anything or hasten it. (Ponyville will begin to grow, but it will do so slowly. Mayor Mare and the local community will not take any steps to accelerate it.)
