(CNN) When Áine Peterson saw images of child migrants being detained at the US-Mexico border, the 7-year-old decided she couldn't stay silent about injustices in the world.

While some politicians see a divisive wall as a solution to the immigration crisis, Áine, who calls herself "the Kind Crusader," envisions a wall to bring people together.

"I want to put together a kindness wall, with art from people all around the world," she says in a video promoting her campaign. Behind her, a homemade poster reads: "Though I be but little, I am fierce."

With her mother's help, Áine launched a GoFundMe page calling for people of all ages to send her artwork for "Wall of Kindness," which would be displayed for the public near her Colorado home.

"This wall will be like everyone in the world is holding hands together in kindness," Áine said.
