The Anthropocene extinction threatens to make all non-human great ape species extinct in the wild by the end of the century. Great apes are particularly vulnerable to Anthropogenic threats due to their slow life history, long inter-birth intervals, and low population densities \cite{Purvis2000}. Habitat destruction, climate change, pollution and synergistic effects between all of these have already enormously reduced great ape ranges worldwide, and the impacts are predicted to worsen for all great ape species over time \cite{Carvalho_2021} .
