The idea was conceived by advertising agency Ogilvy & Mather, who were commissioned by banking giant HSBC to promote its £50million project tackling climate change.

The Ogilvy team came up with an innovative way to show the adverse impact of global climate change.They glued an aerial view of a city to the base of a swimming pool. When the pool was filled with water, it gave a shocking effect akin to a city submerged in water.

The visual of a sunken city shocked swimmers and onlookers, driving home the impact of global warming, and how it could destroy our world someday.
