I think that more sport should be played in schools.

Junk food is one of d reason for public ill-health...

What are some of the ways more sports facilities help solve public health problems?

I think that a problem is very serious. We don't take care of herself. We eat bad and irregularly, don't sleep enough, we have more stress, more work. Additionally our scientist still modify food what is not really good. In our food is more and more chemicals like E220, E190 etc.

Public health problem is a complex problem. It's not only about popularizing sports and building stadiums, gyms. It's also about quality medicine, healthy food, hygiene, sanitation, improving living conditions and many many more. By building new infrastructure i think you will get decreased crime rate among active part of population, less smokers, more people with better immunity to deseases and more gold medals in Olympics. And that's about it. You also need to spend a hefty amount of your country's budget on the issues posted above.
