Temperatures on the tube are going to exceed the legal limit for transporting cattleWatch
How do you think people in hot countries cope?
Because while being transported, and we all know the brutal disregard for animals for commercial/farming purposes. they will probably be exposed to the heat of the vehicle, the interior, the heat of other cattle, all which would raise the temperature to dangerous levels.
Kind of like the tension rating of a rope, it is deliberately (afaik) lower than can theoretically sustain.\
I dont know all the regulations so.
