How many rhinos were there 50 years ago?

Fifty years ago, in the early 1970s, the population of rhinos was significantly higher than it is today. At that time, it is estimated that there were around 70,000 to 100,000 rhinos across various species. However, due to poaching and habitat loss, their numbers have drastically declined since then, leading to increased conservation efforts. Today, the population of rhinos is much lower, with some species, like the northern white rhino, facing near extinction.
