There’s probably not one problem but several problems. The main problem since decades is, of course, the money. Every zoo needs more money for better enclosures. That’s an everlasting problem, I think, in the future as well. But one problem is the import and export of animals. That becomes more and more difficult, more and more paperwork, more and more airlines no longer transport animals. These things are really a difficulty. In former times, you could ship an animal from City A to City B by direct plane.
