Green Zones

Directory Green zones are primary used in high manufacturing planets/cities that run the risk of ruining the air they breath and the atmosphere through smog and smoke.

Green zones are dedicated areas to for growing and keeping a large amount of trees.

Some, like Quinus, have entire districts that act as green zones and public parks.

Others use the roofs of buildings to act as groweries.

Some just have large parks in the middle of their cities. Most places started, and advising others to, setting up green zones after the unfreezing on Halnoris, where the Halar destroyed their atmosphere to the point where it could not longer protect their planet's frozen poles from the heat of the sun.
