Sure, but now place your grass comment in the Fallout world. Have you seen any grass in Fallout 1, 2, Tactics, 3 or New Vegas? I sure as hell didn't.
If I remember correctly there is a person in Fallout 1 or 2 that explains about the death of a lot of species, including horses. The only thing I'm wondering then is how in earth did the cows survive and mutate into twoheaded brahmin? Must have been some sturdy beasts.
Ummm No, I have seen grass in Many places in New Vegas (in the Mojave no less), and also in Fo3. I'm not sure what game you played, but its definitely there. And again, if all grass died then that means ones of the lowest forms of plant life was totally eradicated - nothing else would survive. Yet the radiation at Chernobyl and directly around it was FAR higher than what any nuclear war will produce in a given area, and high radiation would be limited to direct blast areas. Face it - Grass Survives. Thats not even debatable - read the science of Chernobyl on what was killed, not killed and how fast nature COMES BACK. Seeds are not all killed, and grass is incredibly pervasive.
Thats why Cows and Horses would survive - there is plenty of their food around (alot more than ours I would add), and people would cherish them as they have for the last 3,000+ years of human civilization. Only in our modern times (the 20th century in fact) that this changed because of the car, but those all stopped working. Horses would not.
@GabrielDan - One can think of horses legs as critical, just as ours are, and yes when a horse looses a leg it has to be put down. But also remember; we humans have been using horses in ALL forms of warfare for thousands of years - and yeah horses do get killed. But they are also incredibly hardy, and can survive injuries that we would not - they can serious wounds and remain standing while patched-up. The thing is that horses don't think like Cats, Dogs and other domesticated animals - they can endure Alot.
For my part I fall to history, and as a student of military history (especially that of mounted warfare), history is littered with Thousands of examples of huge battles where thousands of horse-mounted warriors rode right into enemy fire of All kinds. It's the speed that wins the battle, as if a horse is charging you in battle - as a foot soldier you have the inevitable fear of being run down, and horses close distances between enemies Very fast. If a strafing fiend is hard to hit, a horse moving at 20 or 30 MPH (even with large size) is actually harder. It's why horses have been the most successful animal in the history of human warfare - and there is just no way they were all wiped out. After the apocolypse, they will be THE mode of transportation - humans will throw their own kind in front of enemeis to save a trusted mount. And don't for a second think we horse people would make armor and protect the horses as much as possible.
Like I said, the Fallout universe got the horses backwards - I don't think there were many horse-people who came up with that part of the lore.
Either that, or they didn't want to hassle with the animation and coding challenges that horses present, and left them out more from practicality than from a desire Not to have horses in their version of post-apocalyptic America. I would love to debate the point with those that make the lore, but this is just a video game in the end and they've written this bit of lore (albiet wrongly) into Fallout gaming history already.
