Okay, so have you ever seen a plant grow from a tiny seed? The earth is like a big garden where lots of plants and animals live. Earth mother is like the name we give to the earth because it takes care of everything that lives in it, just like a real mother takes care of her children.
Earth mother gives us everything we need to live like air to breathe, water to drink, food to eat, and a place to live. She also controls the weather and climate, which means whether it's going to be hot or cold, rainy or sunny.
Just like how we should take care of our moms because they take care of us, we should take care of the earth because it takes care of us. We should recycle, use less energy, and be kind to animals and plants so the earth can keep being a healthy and happy home for all of us. Does that make sense?
