Lee Berger, anthropologist and paleontologist working in South Africa:

"Is it right or wrong to save these species wherever we can? My gut feel as a human is, absolutely. My answer as a scientist is that we have to use measures that are both sensitive to the environments we're putting animals in, while at the same time are conscious of the situation where these animals come from. ...

"We can make mistakes as humans. … There are plenty of cases where we've introduced species that weren't indigenous to the area that have caused huge destruction in that area. On the other hand, there are plenty of cases where moving animals out of their indigenous habitats into areas that have greater protection have effectively saved those species from extinction.

"What's the right answer? Every person, every conservationist, every individual, has to answer for themselves."

Dave Salmoni response:
"Dr. Berger makes the point that we are all responsible for the decisions we make. We have taken a bold step in our conservation methodology and will ultimately be responsible for whatever happens as a result of it. If we as individuals sit back and watch the tiger vanish from the wild than we must take our share of the blame for not trying everything that we possibly could to help stop it."
