The Chilean capital is among the most polluted cities in Latin America and rising levels of smog have led to a first 'environmental emergency' to be declared in 16 years.
SANTIAGO, Chile -- Santiago has declared an environmental emergency due to rising levels of smog and poor air quality with Copa America host Chile scheduled to play Uruguay in the first quarterfinal in the Estadio Nacional on Wednesday.
