(CNN) -- Growing up as an "Army brat," actress Julianne Moore bounced around the United States and witnessed first-hand the needs of underprivileged children in her own country.
Now, Moore is an artist ambassador for the global charity Save the Children, which reaches more than 70,000 children in the United States a year.
"When people say, 'How did you become involved? Is it ... are you acting as a mother? Is it what you see as a mother?' I'm like, no, it's what I saw as a child," Moore said.
Early in her life, Moore noticed that not all kids had lives that were created equal.
"Everybody should have the same opportunity," Moore said. "But the problem, obviously, is that there is not always enough money."
She said many are shocked to hear that one in five children live in poverty in the United States.
"It's not that I don't believe there are many, many needy causes all over the world, particularly in the Third World, but I do believe in terms of poverty in our country, often, people hide in plain sight," Moore said. "There's a refusal, because we have so much in the United States. There's sometimes a refusal to acknowledge what's going on right here."
According to Save the Children's website, Moore has helped ensure rural students have strong reading skills.
Reading has been a lifelong passion for Moore. During her very mobile childhood, friends were fleeting. Books became her constant companion.
"One thing I say about reading to children is that you can really, you can do anything if you can read," Moore said.
Moore is now the author of two children's books featuring a character named Freckleface Strawberry -- a nickname the actress detested as a kid. The books carry a message of acceptance -- freckles and all.
She said education is about connecting with children, allowing them to develop and fostering them into adulthood.
"If we are going to set an example, we need to help everybody here," Moore said. "We need to bring everybody to the same place."
