There will be 75 candles on his birthday cake and Smokey Bear still hopes none of them start a forest fire.

The icon of the longest-running public service campaign in the U.S. is being honored with birthday parties around the country this week, a celebration that includes a social media campaign to share his safety message.

"My friends at the U.S. Forest Service and National Association of State Foresters are counting on #OnlyYou to send in your videos to celebrate my 75th birthday!" Smokey urges residents on his official Facebook page, operated by the agency and nonprofit group. "Take a video singing 'Happy Birthday' to me, your pal Smokey Bear and use the hashtag #SingForSmokey."

Besides the social media campaign, the U.S. Forest Service and National Association of State Foresters are using voices of CBS "Late Night" host Stephen Colbert, Al Roker of NBC's "Today Show", comedian Jeff Foxworthy and Betty White with an animated talking Smokey on online videos.

Smokey promoters also have shared vintage fire prevention videos like the 1968 commercial with the bear and "Twilight Zone" creator Rod Sterling.

Smokey Bear was born on Aug. 9, 1944, when the U.S. Forest Service and the Ad Council agreed that a fictional bear would be the symbol for a fire prevention campaign. At the time, federal officials feared the nation's national forest could become targets as the country was deep into World War II.

Six years later, firefighters found a cub with severely burned paws and hind legs in the aftermath of a blaze in New Mexico's Capitan Mountains. The cub was named Smokey Bear after a New York Assistant Fire Chief, "Smokey" Joe Martin.

When the bear died in 1976, his remains were buried in what is now Smokey Bear Historical Park in Capitan, — not far from where he was found.

This week, the Gila National Forest in Silver City, New Mexico, and Wingfield Park in Ruidoso will hold community birthday parties for the bear. Parties also are scheduled in Reading, Pennsylvania, and Entiat, Washington.

Smokey Bear is also set to return to the Macy's Thanksgiving Day Parade later this fall. He first debuted in the 1966 parade and took part in the holiday spectacle every year until 1981. Smokey made his last appearance in 1993 in celebration of his 50th birthday.

Smokey's anniversary comes as scientists warn the world's forests are vulnerable amid climate change. Human-caused wildfires remain one of their biggest concerns.

According to a study published in February 2017 in the Proceedings of the National Academy of Sciences , 84% of the blazes that firefighters were called to fight in the U.S. between 1992 and 2012 were ignited by people.
