TIME 100 #TIME4Change

April 21, 2015 1:31 PM EDT

The TIME 100 recognizes the world’s most influential people. From Julianna Margulies‘ push to pass Erin’s Law, a sexual assault prevention bill for children, to Bryan Stevenson and his work on the Equal Justice Initiative, the 2015 TIME 100’s focus is on making the world a better place.

Help support the TIME 100—especially those who work under the radar and in small communities—by drawing attention to their causes with the hashtag #TIME4Change.

Erin’s Law provides personal body safety taught to kids in Pre-K-12th grade. The law requires schools to teach kids the differences between safe and unsafe touches, safe and unsafe secrets, empowering students to speak up and tell if they are being abused instead of keeping it a secret. Founder and survivor of child sexual abuse Erin Merryn has made it her personal mission to get Erin’s Law passed in all 50 states going capital to capital testify to lawmakers. Currently Erin’s Law is passed in 21 states and pending in 22 others.

Project A.L.S. is a non-profit 501(c) 3 whose mission is to identify and support aggressive research toward treatments and a cure for ALS, also known as Lou Gehrig’s disease. It was founded by producer Jenifer Estess in 1998, when she was diagnosed with the disease at age 35. ALS is a devastating brain disease that is closely related to Alzheimer’s and Parkinson’s and robs people of the ability to walk, speak, swallow and breathe. www.projectals.org
