Cities are finally realizing that human infrastructure can pull double duty to save the planet. In Utrecht, Netherlands, over 300 bus stops have been completely transformed into "bee stops" featuring green roofs planted with native sedum wildflowers. These miniature urban oases capture rainwater, absorb fine dust, cool down the pavement during heatwaves, and provide essential pit stops for endangered pollinators navigating the concrete city maze. The best part? It's paid for entirely by the city's standard transit budget.
