🌳 TREES ARE MORE THAN BEAUTIFUL—THEY ARE PUBLIC HEALTH INFRASTRUCTURE.
A new study published in GeoHealth examined more than 220,000 deaths across Chicago neighborhoods from 2011–2021 and found a powerful connection between changes in urban tree canopy and mortality.
The research found that neighborhoods experiencing year-to-year increases in tree canopy had lower associated mortality, including lower mortality related to cardiovascular, respiratory, musculoskeletal, and mental health conditions.
And here’s the part we can’t ignore:
🌡️ The hottest neighborhoods experienced greater harm when tree canopy was lost.
🌳 Protecting existing trees matters—not just planting new ones.
🏘️ Tree canopy is an environmental justice issue.
❤️ Where we plant, where we maintain, and where we protect trees can have profound implications for community health and resilience.
This research reinforces what we believe at We Plant It Forward:
Planting trees isn’t just about changing the landscape. It’s about changing lives.
Let’s continue planting.
Let’s protect the trees we already have.
Let’s invest in neighborhoods that need shade, cooling, and healthy green spaces the most.
🌱 Trees are an investment in healthier, cooler, more resilient communities.
