Zoos and aquaria have gone through a number of changes over the last 150 years. They began as expressions of colonial reach and power (pre-1900) but then developed into institutions of civic pride before morphing into conservation centers in the last fgifty years of the 20th century. They are now heavily involved in public education. With the world's wildlife on the edge of catastrophe, zoos and aquaria must now use their public reach as effectively as possible to influence global policy on wildlife protection and conservation.
