Kingfisher and soil erosion

Monday, 20 December

S2 Ep 26. A very clever solution to a significant environmental problem based on a kingfisher’s eyelids.

Architects have copied this design to help prevent soil erosion on the banks of the huge Three Gorges Dam in China. Get in touch: www.bbcworldservice.com/30animals #30Animals
