Almap BBDO Brazil recently made a very creative online ad for Greenpeace..
When you see a video in Youtube, you have the red bar below that gives the length of the video.
The red bar represents the ‘Earth Temperature’ and the yellow bar above represents the ‘Climate Conditions’.
At the right you see their slogan ‘Stob Global Warming’..

Nice way to show the impact of global warming on climate conditions, the ocean level and the biodiversity
Such a simple idea, but deep respect for the team who came up with this..
