To the editor:

As “The Big Bang Theory” CBS juggernaut rolls into a record 12th season on Sept. 24, most of the gang exploring mysteries of the universe have gone vegan, opting for plant-based eating.

Lead actress Kaley Cuoco (Penny) also campaigns against Canadian slaughter of baby seals. Mayim Bialik (Amy) and Kunal Ayyar (Raj) are asking the United States to join the European Union in ending cruel cosmetic testing on animals. Johnny Galecki (Leonard) did it for personal health.

Dozens of other celebrity entertainers have gone vegan in recent years. They include Casey Affleck, Pamela Anderson, Alec Baldwin, Bob Barker, Beyonce, James Cameron, Jessica Chastain, Miley Cyrus, Ellen DeGeneres, Emily Deschanel, Peter Dinklage, Sara Gilbert, Ariana Grande, Daryl Hannah, Woody Harrelson, Anne Hathaway, Jennifer Lopez, Madonna, Tobey Maguire, Demi Moore, Michelle Pfeiffer, Joaquin Phoenix, Brad Pitt, Natalie Portman, Alicia Silverstone and Stevie Wonder.

Most seek to avoid oppressing and killing animals. Some look to reduce their risk of obesity, diabetes, heart disease, stroke and cancer. Still others care about the devastating impacts of animal agriculture on climate change, water quality and wildlife habitats.

Compelling reasons for every one of us, as we get ready for “The Big Bang Theory” Season 12!
