Some seals in South Africa are testing positive for rabies.

Research has indicated that Bovine TB originated in Humans not the other other way around.

Possible origin is Bison 17 thousand years ago, though its not 100% certain. There are plenty of other livestock/pet originating diseases, though mostly dont affect europe

I totally agree. I don't know why people regurgitate the trope that the wildlife is out to get us. It simply isn't true (biting invertebrates excepted). Mammals will generally avoid conflict and will only attack you if they feel cornered (so can't escape the perceived threat) or think you're a threat to their young.

As you say, it generally isn't true - wildlife will mostly avoid us. BUT! If animals don't have an avenue to retreat, then the fight side of "fight or flight" responses kicks in. Get between a seal and the sea and that cuts down it's options. Get between a seal cow and it's pup or a bull and its harem, and you're asking for trouble. Some species are also naturally more aggressive than others; fur seals are particularly likely to attack without provocation.
