The smog alert, which was issued by meteorologists on Sunday, has been
called off in the Moravian-Silesian region. As a long-term solution to the
air pollution in the area, the Ostrava city hall is planning to plant
hundreds of thousands of new trees around the city, which should separate
industrial zones from residential ones and help collect dust participles
in
the air. Smog alerts are a common occurrence in winters in the Ostrava
region, as well as in the Karvina, Frydek-Místek and Třínec regions,
which are all industrial centers.
