Copacii bătrâni ar putea proteja sănătatea mai mult decât cei nou plantați. Ce arată un studiu din Chicago

A long-term study in Chicago indicates that preserving mature trees may significantly impact public health more than planting new ones. Researchers found a correlation between urban vegetation changes and mortality rates, emphasizing the importance of canopy coverage rather than tree count. Areas with declining canopy coverage experienced increased mortality, particularly from cardiovascular and respiratory diseases. The study suggests that maintaining existing trees could be as crucial as planting new ones, as young trees take time to provide similar health benefits.
