Steve founded the 'Steve Irwin Conservation Foundation,' which became an independent charity and was later renamed 'Wildlife Warriors Worldwide.' He also helped found 'International Crocodile Rescue, 'the 'Lyn Irwin Memorial Fund' (named in memory of his mother, who died in an automobile crash in 2000), and the 'Iron Bark Station Wildlife Rehabilitation Facility.'
I'm sure Steve Irwin's reaction the the sting ray that accidentally killed him would be to say something like "I'm sorry I scared you, I just wanted everyone to see how awesome you are."
