Mark Zuckerberg is the boss of Meta. Meta makes Instagram. He is in court in Los Angeles. This is very important.

A young woman says Instagram hurts children. Her name is K.G.M. She is 20 years old now. She says she starts using Instagram when she is nine years old. She says Instagram makes children very sad. She says it is very difficult to stop using Instagram.

Zuckerberg says this is not true. He says Meta does not want to hurt children. He says Meta tries to keep children safe.

The lawyers show documents from Meta. The documents say Meta wants people to use Instagram for a long time every day. Many people think this is a problem.
