Ocean

Did you know why Earth is called the 'Blue Planet?
It's because of the oceans,
the huge water places that cover most of our planet.
Oceans have salty water and many types of creatures.
We find fish, crabs, and even giant whales in the ocean.
The ocean is important because it gives us food and helps control the Earth's climate.
But we need to protect it by not throwing trash in the water.
This keeps it clean for all ocean animals.
