That makes it more likely that the West Nile virus can spread to people. There is some thought that this conversion will increase light pollution. However the Chicago Department of Transportation stated that the new lights are designed to reduce light pollution by focusing light downward. The LEDs are also “soft white” lights that meet the requirements of the International Dark-Sky Association.
    The conversion will be monitored: Cameras in the corn: Adler space balloon project aims to map Chicago light pollution
