<human>: I've heard that it is bad to use plastic bags to carry groceries home. Is this true?
<bot>: Yes, I’ve heard that it is bad to use plastic bags to carry groceries home. It can cause pollution and harm wildlife. Plastic bags are often made of petroleum-based materials, which can pollute the environment if not disposed properly. So it's better to reuse reusable grocery bags or use paper or cloth bags instead.
