The child actress, who went on to star in nine seasons of "Roseanne," several iconic films, and spearhead a wildly successful talk show, also wrote a book. Over the years, Sara Gilbert has been involved in causes related to environmental issues, LGBTQ+ rights, and animal welfare. She has expressed her views on these topics through public appearances, interviews, and social media, and in 2013 she published a book.

"The Imperfect Environmentalist: A Practical Guide to Clearing Your Body, Detoxing Your Home and Saving The Earth (Without Losing Your Mind)" was Gilbert's attempt to inspire people to make small changes in their lives, which would have a big impact difference. "It's not that big of a deal to switch to eco-friendly makeup or glass containers to store food," she explained in an interview with USA Today.

Gilbert said the most shocking information she sourced during her research was that children are going through puberty five years earlier than they did 100 years ago because of hormone disruptions in our environment. "That's why it's important to buy organic," she added. Gilbert says she was an environmentalist as a teen but she lost sight of it as her career burgeoned. Being a mom made her aware of the issues again and she wanted to do her bit "to leave the world a better place for them."
