Most poaching deaths are most certainly not for food. Why would the poachers go for rhino, elephants when there are millions of wildebeest and impala to eat rather than go for ones that are hard to find. It is because of the ivory and horn.
I lived in Africa for 18 years and have seen poaching with my own eyes and they were after antelope for food not horn or ivory.
East African savannah countries I think is more likely poaching is too sell animal products re ivory and horn. However don’t forget poaching in the national parks of West Africa, or countries like Burundi, Rwanda, Congo, Uganda etc. These countries are more jungle like with far less antelope and the like to eat, so eating ‘bush meat’ is common and that can include endangered apes etc.
Also have no stats to back that up.
