What is another word for the three rs?
Pronunciation: [ðə θɹˈiː ˌɑːɹˈɛs] (IPA) 
The phrase "the three Rs" originally referred to the pillars of education - reading, writing, and arithmetic. However, as environmentalism has become more prominent, the term has also come to refer to waste reduction: reduce, reuse, and recycle. These three actions are seen as essential to reduce waste, decrease environmental damage, and save resources. Some also use the phrase "the three Rs" to describe animal welfare practices - replace, reduce, and refine - which aim to reduce the use of animals in research while improving their welfare. Regardless of the context, "the three Rs" represent important practices that promote sustainability, efficiency, and compassion.
