Good idea: vertical gardens to cool down cities https://www.euronews.com/2026/05/25/vertical-gardens-are-a-practical-and-beautiful-way-to-cool-down-cities Since French botanist Patrick Blanc pioneered the concept in the 1980s, Europe has produced some striking examples. Milan’s Bosco Verticale, a pair of residential skyscrapers whose terraces hold more than 21,000 trees and shrubs, converts nearly 20,000 kilograms of carbon annually and now shelters 20 species of birds. As Europe’s capitals brace for yet another summer of blistering heatwaves, building on this legacy could be one of the most practical tools for protecting citizens. #verticalgardens, #urbangreening, #greencities
