New York's Million Trees Initiative Cools City
New York City planted one million trees between 2007 and 2015 to make the city cooler and greener.
This initiative, called MillionTreesNYC, cost about $400 million and helped shade streets, improve air quality, and reduce heat.
The trees also provide economic benefits, like lowering cooling costs and capturing stormwater.
The city is now focusing on preserving these trees and expanding the tree canopy, especially in areas that get very hot.
This helps make the city more resilient to climate change and reduces inequality in how different neighborhoods experience heat.
