A recent episode of the Sustainability in Your Ear podcast features ecological engineer Nadina Galle discussing her book on integrating nature and technology in cities.
More than half the world’s population, or 4.4 billion people, currently live in cities, with that share projected to reach 80 percent by 2050. Galle, author of The Nature of Our Cities, introduced the Internet of Nature concept, which applies artificial intelligence, automation, and sensors to support urban ecosystems.

In an essay published in PLOS Climate, they argue that planting and maintaining trees must become a legal requirement to address rising temperatures, flooding, and health issues.
