How to grow Chicago's dwindling tree canopy

While trees seem to be everywhere in Chicago, the city is having to remove trees faster than it can replace them, whether due to pest infestation or storm damage. And as the city is feeling the effects of climate change with higher temperatures and derechos, the importance of tree coverage across the city has come to the forefront. The Daily Line's Erin Hegarty spoke with Malcolm Whiteside, head of the city's Forestry Bureau, and Cook County Comm. Bridget Degnen (D-12), chair of the Cook County Environmental Commission, about the city's tree stock and what's being done to expand the canopy.
