Actually in forests if Tigers are injured, they are unable to hunt their prey, either they try to scavange or wait for injury to heal or they die of hunger.
So this poster is wrong..!!
But.......... There is one more case..!!
In other regions if the forest is close to the village then an injured tiger turn to cattle liftung and even maneating, and if a tiger turns into a maneater then it becomes way more dangerous & deadly..!!
So in this case, this poster is correct..!!
Full marks to YRF for getting it scientifically & naturally correct, but honestly poster isn't that impact full as expected..!!
