The life of animals raised in confinement on industrial farms is slowly improving, thanks to pressure from consumers, animal rights advocates, farmers and legislators. In late June, a compromise was reached in Ohio that will gradually put an end to the tiny pens used for raising veal calves and holding pregnant sows, spaces so small the animals can barely move.

In California last week, Gov. Arnold Schwarzenegger signed a law requiring that all whole eggs sold in the state conform to the provisions of Proposition 2, the humane farming law that was embraced by state voters in a landslide in 2008. By 2015, every whole egg sold in the state must come from a hen that is able to stretch her wings, standing or lying, without touching another bird or the edges of her cage. This requirement would at least relieve the worst of the production horrors that are common in the industry now.

Since California does not produce all the eggs it eats, this new law will have a wider effect on the industry; every producer who hopes to sell eggs in the state must meet its regulations.

Heartening as these developments are, there is also strong resistance from the food industry and from fake consumer-advocacy groups that are shilling for it.

In fact, there is no justification, economic or otherwise, for the abusive practice of confining animals in spaces barely larger than the volume of their bodies. Animals with more space are healthier, and they are no less productive.

Industrial confinement is cruel and senseless and will turn out to be, we hope, a relatively short-lived anomaly in modern farming.
