Japan's World Expo: The Bio Lung Experiment - Combining Nature and Innovation

The video discusses the concept of a 'bio lung' at the IEG World Expo, featuring walls of plants and trees on terraces and roofs. These plants serve both aesthetic and functional purposes, such as cooling the environment and monitoring CO2 levels. The bio lung includes 231 plant species, each with specific soil needs, and is equipped with sensors to track environmental changes. This innovation is highlighted as a significant feature of the expo.
