Reducing is making less waste. (Example: The recycling company will turn the objects into something else which means they are taking that and making something else out of it and it's taking all the waste to a minimum on earth.

Reusing in recycling means to use it then to use it, again. Example: The kid drank out of the glass bottle and used it for water later.

Recycling is when you have an object (paper, aluminum, etc.) and you reuse it, take it to a local recycling company, or reduce it.
