New research in the UK suggests people do not know just how endangered tigers are, with just over 3,000 remaining in the wild.
A survey has found that people in the UK think there are around 17,000 remaining.
Irish television presenter Liz Bonnin, who now works for BBC as a wildlife and science presenter, is fronting the campaign for "the plight of the tiger".
"Numbers have been worryingly low for quite a long time," she warned.
"It's about awareness and education, and maybe us, as a global population, focusing on other things.
"They're literally on the brink of extinction now."
