World Wildlife Fund Ad

WHO? World Wildlife Fund (WWF)

WHAT? The WWF created a billboard that uses an awning to cast a shadow that rises throughout the day. This shadow rising demonstrates the rising ocean levels due to global warming, which is detrimental to our society.

GOAL? The goal is to show a mass group of people how quickly ocean levels can rise and that it is a detriment to our society.
