I also think it's worth mentioning about the appallingly low number of Bears in UK collections before these rescues became a thing. I remember there being a thread on this here around 2008 discussing it, where the only bears we had were the spectacled at Belfast, Chester, and Jersey, the sun at Belfast, the browns at Whipsnade, the two sloth at ZSL, the single Polar Bear in Scotland, with another at Heythrop, and the blacks at Woburn and Dudley. There have been quite a good number added since then, in no small part to these bear rescues.
