In a time where everyone sues everyone for the most trifle things, that's quite recommendable.
Given that Mc D's is mentioned as a sponsor at Kaunas Zoo, I'm pretty sure the management of the local branch knows about this situation. Whether the big CEOs in the USA know about the husbandry conditions of polar bears in a Lithuanian and actually care about that, is another thing.
As for the second plaque: ever watched the Coca Cola Polar Bear commercials in the 1990s?
Sure, Prague Zoo receives more money from the state than any other Czech zoo. However, a former director highly interested in PR, a experienced zoo staff with plenty of connections to pretty much all major zoos, a historic tradition of exotic animal husbandry both in Czech zoos and private households, a location in a city prominent in global tourism etc. etc. are all factors Kaunas can't compete with. Kaunas is a nice little town with lots of friendly people in it. But zoo-wise, a lot has to be improved-and the locals (or at least some) know that.
The polar bear enclosure is currently empty. There are no polar bears anymore at this zoo and no plans to bring new ones.
To talk about bulldozers is pointless. Zoos like this can change themselves into amazing or at least decent places, maybe not overnight, but they can. They just need financial funds, support from local politicians and most importantly a person (or persons) with a vision and exceptional management skills.
Look for example at Wroclaw. The director is right now turning the stagnant old-fashioned place into something exciting. He did the same with Poznan few years back. Or look at Budapest, how they´ve renovated the zoo grounds by respecting the old substance and still with so many exciting plans for the next years. Or how Plzen drastically changed, the place was little more then a run-down road-side-like zoo just 15 years ago. The same with Zlin, Sosto, Opole, Zamosc. Ostrava is curretly in the middle of a similar revolution, the same Szeged and many more.
