Back when my parents were at primary school, a large emphasis was placed on the 3 R’s – reading, writing and arithmetic.
In more recent years, a second set of 3 R’s (which all actually start with the letter R this time) has been introduced. Reduce, reuse and recycle is the modern mantra taught to encourage social responsibility through waste management.
The 3 R’s are meant to be a hierarchy, in order of importance. Hence, we should start by reducing what we use, followed by reusing, then recycling.
