Paris chuckled. Sure they had removed horses as a mean of transporting themselves, but they couldn't get rid of all the animals they already had. Horses would most likely go extinct without humans now when they had forced them to be dependent on them. It had been many hundreds of years since the last wild horses had disappeared. It wasn't just for the animals sake they kept using them though. Everyone liked animals, even if they weren't too fond of nature. Just like some had cats and dogs, others took a step further and got themselves a horse, or a whole farm.
"We don't use them for transportation though. Cars, buses, trains, air planes. They're all made to take us from point A to point B as fast as possible." The prince started to explain. "Horses are more like friends you share a fun activity with. Some ride them as a sport, and others just ride them as a fun activity during their free time. In return we give them shelter, food, a loving home and take care of them. Sure there are people who only uses them to win prizes and doesn't care much about the animals well being. But most horse owners love them just as much as they would their house cat or dog, or even friends and siblings." There were certainly people who though the same way of their car. Heck there were people actually marrying their cars. But Adrian could probably wait with learning about those things. Start with the good in this new culture, and then go to the bad.
"The only thing connecting us with nature right now is probably our animals. Though considering most animal species owned by humans hasn't lived in nature for at least a few hundred years, I guess it doesn't count much."
