The difference between an Amur tiger and a Sumatran tiger is fairly apparent. But the fact of the matter is that genetically they are very close. So whether whether we will be able to sustain the remaining races of tiger or not is highly questionable. I’d have to say, I don’t think so. Sustaining tigers at all though is the big question. A single tiger in nature takes about 50 substantial animals, deer sized animals every year, one tiger. Now multiply that by the number of tigers you need to sustain a viable population of tigers, that is arguable, but we’ll take a minimum figure 250. Now to supply it with deer, that tiger has to have its deer once a week.
