Urban sprawl happens when people start to develop land without planning
it out very well. This is called poor planned growth. To help with spreading,
cities can follow some of these steps.
If cities do these, they have a chance of saving rural area and causing less poulltion.
For example, more traffic causes more smog. More smog causes more lung problems.
Having a
smaller city means there is less traffic.
The left side shows smog and the right side has no smog. Warn your city and stop the sprawl!
