All of the studbook-registered captive population is maintained in Indian zoos, except for one female Bengal tiger in North America.
Furthermore, tigers are an apex predator and a keystone species in their native range, meaning their existence in a foreign environment could have a major ecological impact.
If successful, introduction of tigers in Africa could lead to them outcompeting other big cat species such as lions, leopards, and cheetahs while simultaneously decimating populations of native prey fauna.
Because tigers are a top predator, this could have a trickle down effect, subsequently having a negative impact on smaller animals and also plants.
Cory Meacham, a US-based environmental journalist mentioned that "the film has about as much to do with tiger conservation as a Disney cartoon."
An additional assertion is that the tigers have not been released and still reside in a small enclosure under constant watch and with frequent human contact.
