In this ad to save the polar bears, WWF plays off of that disappointing message that you sometimes come across stating that "This content is no longer available."
The video is deceptively named 'Polar Bears Hugging,' but rather than seeing a super cute video of an animal embrace, the video is all black static and text, communicating that the video is no longer available due to global warming. The video also takes care to state that "In just 40 years, more than 50% of the world's wild life has disappeared." At the end of the ad, WWF encourages viewers to bring awareness to the issue by sharing the video with others online.
It's disheartening to click on the video and not see any polar bears, but it will be even worse if they're wiped out forever.
