Voting YES! on Prop 2...

• Prevents cruelty to animals.
  It’s simply wrong to confine veal calves, breeding pigs, and egg-laying hens in tiny cages barely larger than their bodies. Calves are tethered by the neck and can barely move, pigs in severe confinement bite the metal bars of their crates, and hens get trapped and even impaled in their wire cages. We wouldn’t force our pets to live in filthy, cramped cages for their whole lives, and we shouldn’t force farm animals to endure such misery. All animals, including those raised for food, deserve humane treatment.
• Improves our health and food safety.
  We all witnessed the cruel treatment of sick and crippled cows exposed by a Southern California slaughter plant investigation this year, prompting authorities to pull meat off school menus and initiate a nationwide recall. Factory farms put our health at risk—cramming tens of thousands of animals into tiny cages, fostering the spread of diseases that may affect people. YES! on Prop 2 is better for animals—and for us.
• Supports family farmers.
  California family farmers support YES! on Prop 2 because they know that better farming practices enhance food quality and safety. Increasingly, they’re supplying major retailers like Safeway and Burger King. Factory farms cut corners and drive family farmers out of business when they put profits ahead of animal welfare and our health.
• Protects air and water and safeguards the environment.
  The American Public Health Association has called for a moratorium on new factory farms because of the devastating effects these operations can have on surrounding communities, spreading untreated waste on the ground and contaminating our waterways, lakes, groundwater, soil, and air. Prop 2 helps stop some of the worst abuses and protects our precious natural resources. That’s why California Clean Water Action and Sierra Club support YES! on Prop 2.
• A reasonable and common-sense reform.
  Prop 2 provides ample time—until 2015—for factory farms using these severe confinement methods to shift to more humane practices. Arizona, Colorado, Florida, and Oregon have passed similar laws. The Humane Society of the United States, California veterinarians, including the California Veterinary Medical Association; family farmers; Center for Food Safety, Consumer Federation of America, Center for Science in the Public Interest, Cesar Chavez Foundation, the prestigious Pew Commission on animal agriculture; Republican and Democratic elected officials; leaders of the Episcopal, Methodist, and Catholic churches; and others recommend voting YES! on Prop 2.
