Which breed of tigers is there most?

The most abundant species of tiger at the moment is the Amur, or Siberian tiger, which is also the biggest in size. The others, which are the Indian, Bengal, and Indonesian tigers, are much lower in numbers and are barely clinging to survival. Even the Siberian tiger is endangered to the hundreds. These creatures really need some help getting back on their feet because the Chinese are hunting them for their body parts because they are ingredients in many traditional medicines that don't even work. Also, their habitat is getting destroyed and people are hunting them for killing livestock and people. It makes no sense to me. The people are the ones encroaching on their territory and driving all of the prey the tigers usually eat away or hunting the prey as well. They are the ones forcing the tigers to turn to other means of survival, and their blaming the tigers? They need to blame themselves for their actions and give some territory back to the tigers.
