2 D Last week Jay McCarroll and The HSUS(The Humane Society of the United States) made a bold fur-free statement on the runway, marking a new chapter for the fashion industry and animal protection. The encouraging response to McCarroll’s show confirmed that change is happening in fashion. McCarroll has good reasons for rejecting fur. Each year, tens of millions of animals, including dogs and cats, needlessly suffer and die to fuel the fur industry. But what did Jay McCarroll use in place of fur? “I have patchwork pieces that contain all sorts of combinations of fabrics. The rest is cotton, nylon, polyester . . . you name it. I even have some stuff made out of bamboo/cotton blend. Anything but fur and leather, ”he told Fashion Wire Daily. “So many people want to protect animals and live their lives without causing unnecessary cruelty. More than two thirds of Americans have pets, and we share a bond with animals every day. Saying no to fur can help millions of animals, and we want to show our respect to leading designers like Jay who embrace compassion as the fashion, ”said Michael Markarian, executive vice president of The HSUS. “It is great to see leaders in the fashion industry recognizing that the animals need their fur more than we do.” 63．Which of the following is true about Jay McCarroll?
