A new European citizens' initiative is underway to ban the long-distance transport of horses for slaughter and to protect horses from overwork or heavy training. If the initiative garners 1 million signatures from at least seven member states within a year, the European Commission is required to respond. The initiative is part of a larger push for improved animal welfare, following a successful initiative to end the use of cages for animals. The initiative also criticizes the slaughter of horses for human consumption, arguing that it is unnecessary and often illegal, with an estimated 5 million horses killed annually.
