If as mankind we ever want to save these species we do need to think laterally. Very little chance of doing any meaningful species reintroduction to the wild etc in areas / countries with a high degree of Political uncertainty and lack of security. If we want to preserve animals such as Lions, Tigers or Rhinos we will have to think beyond Zoos to build up reserve populations.

So Barbary Lions, for example - parts of Southern Spain for example are sparsely populated, and offer similar habitat and prey species - wild boar.

Or Tigers - well Northern Australia already has a good population of water buffalo and Gaur. Tigers do occur in Indonesia, not far to the North, so again you could use these areas to set up reserve populations, ditto for Rhino.

It would take funds and political will to do so, but in the west, now that we have reasonable standards of living, security, and food security, should n't we thinking wider.

Appreciate that some may be disadvantaged - there is a lot of discussion / controversy over the reintroduction of Sea Eagles to Scotland cos they eat a few scruffy hill sheep, but we need to think on the bigger picture.
