Wild lions, tigers, elephants and rhinos may never be seen by those being born today after experts estimated extinction rates may be faster than previously thought.
Current estimates predict lions and elephants could be extinct by 2025, tigers by 2035, rhinos by 2040, but charity Care For The Wild has now said all four could vanish by 2035.
The charity, at the launch of its Tooth Fairy campaign, said that from its own on-the-ground experience and reports from conservation experts, these species could be extinct in the wild in 22 years' time.
Chris Pitt, campaign and communications manager, said: "There are so many figures out there that we are trying to take a realistic view of extinction rates.
"Poaching is a serious problem and elephant figures are falling fast - in some parts of Africa elephants are now nonexistent - so we are trying to raise awareness of this issue and raise money to help with protection patrols."
It claims that, to date this year, more rhinos will have been killed in South Africa than in 2012 as a whole - an increase of 30%.
There are currently around 35,000 rhinos in Africa but the current birth rate and poaching could lead to their demise as soon as 2025.
Estimates for elephant deaths vary across Africa due to the nature of poaching, and war and poverty in countries elephants are native to. More....
