Do you want those toddlers to grow up with a deep enough appreciation for animals and the natural environment to invest real resources in conservation when they grow up -- even if it means conserving environments in places like Africa and South America that they will likely never see in person?
People only put effort into things they care about, and they only care about what they feel connected too. If we don't make wild animals real to a signification fraction of the voting population, we won't have wild animals for much longer.
I don't know if zoos are the right way. They seem to make people think that wild animals sit around the whole day in tight spaces and play with beach balls. Or people may think that Orcas have nothing better to do than interacting with humans. I think more can be done with documentaries or making wild places more accessible. I think Yellowstone is a good example for people learning how nature can look.
