Far too many buildings are covered with dead skin. Concrete, steel, wood, metal, brick, bitumen, rubber and vinyl are lifeless materials which can and should have a vegetated outer cladding.  Here's an illustrated version of the podcast.

The exteriors of buildings should be planned, designed and managed for multiple objectives including:

1. Habitat creation

2. Horticulture for growing food

3. Horticulture for aesthetics

4. Apiculture (bee keeping)

5. Surface water management

6. Energy capture

7. Carbon capture

8. Dust capture

9. Noise attenuation

10. Thermal insulation

11. Natural lighting and ventilation

12. Relaxation and wellbeing

Green cladding materials are also beautiful sustainable.
