When recycling we are reusing old stuff we get rid of and making it better like for example when you recycle plastic that plastic can turn into a toy for a kid or recycling an old rusty metal that can turn into a bed or a new table. Recycling is really good for the environment because you are changing something old into something new.
Hope this helped :)
