It is pointed out in the passage that the orangutans weren't able to replace those that had died or been stolen because ----.
For thousands of years the wild orangutan lived in
rich tropical forests. The species has no natural
enemy, but in the last three decades it has been
driven to extinction. The main causes for this are
miners, peasants and illegal loggers who have
destroyed the orangutan's habitat on the Indonesian
islands of Sumatra and Borneo. More than half of
these lowland forests were cut down during
President Suharto's autocratic reign, but the change
to democracy in Indonesia in the late 1990s did
nothing to stop the forest clearing. In addition, illegal
hunters have killed more than 1,000 orangutan
mothers per year, stealing their babies to sell on the
black market. Because orangutans breed slowly,
they could not reproduce quickly enough to counter
these threats to their existence and so they died out.
