Dancing with Stars' Bindi Irwin has tweeted an emotional video of her father, the late, great, Steve Irwin, explaining what it would have taken him to give up on his conservation work.
In the video, Steve asks the question, "Is there anything in the world that would make me want to give away what I'm doing now? Yes, there is." He adds: "When my children can take the football I call wildlife conservation and run it up."
"When they're ready to run up our mission, I will gladly step aside," he says, his voice breaking with emotion. "Then, and only then, will I know that I have achieved my ultimate goal. To be able to stand aside and let them run up my mission."
The video, which has been viewed 1.69m times, was posted by his daughter, 19-year-old Bindi, during the Super Bowl - which explains the football analogy.
It received a wave of support, not least from actor Russell Crowe, who tweeted:
Bindi Irwin is perhaps best known to audiences as a winner of the US Dancing with Stars show in 2015, but it was announced last autumn that she would be teaming up with her brother, Robert, and mum, Terri, to produce a series of shows for Discovery Communications, which owns Animal Planet.
Bindi was born in Queensland and appeared in her father's TV shows from an early age. Her dad, Crocodile Hunter Steve, was a world-famous conservationist, known for his enthusiasm, in-depth knowledge and commitment to saving the world's natural environments and endangered species.
After he was tragically killed in 2006 by a stingray barb, Irwin delivered a eulogy for her father, which she'd written herself, at an event attended by 5,000 people and watched by around 300 million worldwide.
In 2015, Steve was posthumously awarded in the Queensland Greats Awards for his outstanding contribution to conservation. He remains a legend.Featured Image Credit: Steve with his wife and Bindi when she was a small child. PA
