Millions of animals are transported in shameful conditions to be slaughtered in the destination country. The journeys are toilsome.
The animals are crammed in trucks driving for hundreds of kilometres, most of the times without even stopping to let them drink or eat. They are exposed to the heat in summer and to the freezing cold of winter nights. Many animals die during the transport and are not removed until the journey is finished, so that dead bodies and alive terrified animals stay for hours side by side.
There are some laws which limit the duration of the trips and somehow regulate the transport conditions, not making them bearable in any case. Many animalists have demonstrated that most of the times this regulation are completely ignored with the total indifference of the authorities.
This way the grieving show of animals getting to destination in agony, or dead for the thirst, cold or hunger never stops.
