Well my car's gas tank is full, so I'll just have to dump the rest of the gas into the river.
Don't do that!
Because it pollutes water, making it undrinkable and unsafe. This is called water pollution. It can also hurt animals.
Oh! I didn't know that!
Oh! Thank you Super Knight!
It's OK, just don't let it happen again. Also, spread the knowledge that, to help reduce water pollution, do not pour any fat from cooking or any other fat or oil or grease down the sink. Keep a jar, so you can store that fat and oil, until you can dispose of it properly.
