True explorers go to jungle and stay there for a month. In mud, rain, bitten by leeches and mosquitoes. Sometimes get a chance to spot some wildlife.
Lazy people, like us, go to places similar to Kuala Lumpur butterfly park (not the same as bird park), pay for the entrance and have a great time watching thousands of selected butterflies and their different cousins flying around.
The chances to see them are 100%.
Showing the photo, I could easily persuade you that it's taken somewhere in a valley of Costa Rica.
The point? Old-fashioned zoo with caged animals is certainly evil, but a new style approach with wildlife roaming unrestricted in a much bigger area is unbeatable in sense of education. In certain cases - conservation.
P.S. Countering the previous post about grim future scenarios, Kuala Lumpur has some great places as well.
