Natural speed please.
If I made a mistake, please feel free to correct it.
Thanks.
The teachers in my school consume a lot of plastic because they need markers to write every day on the whiteboard.
When the marker is empty, they put it in a bin, and therefore they put it in the nature or in the ocean.
The teachers should use a pen made of wood instead of a marker made of plastic. It’s an easy way to stop using plastic. Everybody should do it.
If everybody did it, it would be better for the environment.
However, a pen made of wood is more expensive and it’s harder to clean the board.
