Still waters run deep for diver striving to save the planet

To gauge the health of the planet Wang Miao believes that only by delving into the deep to unlock the secrets of the oceans can we better understand the environment above the waves and the dangers facing the world.

"What causes the pollution that we see on the surface is linked to what is under the waves", the 31-yearold diver says.

Wang obtained a master's in international development from Manchester University in 2013, and worked in the Tibet autonomous region on sanitation projects for two years.
