The problem is most preventable in rural areas and the cities more to the west. Places like Shanghai don't have such an imbalance.
The more likely solution, as opposed to using them for wars, it they get used for domestic construction projects: highways, railroads, etc. This has already been the case.
China is working hard on this problem. Its illegal to know the sex of a child during pregnancy. Some get around the issue, but I have personally seen it upheld pretty well. I knew the sex of my child before he was born, in Shanghai. But I was only allowed to know because I was an American and was in a hospital that catered to foreigners. The locals seem to have mostly settled in on the fact that they aren't supposed to know.
