Answer:
The principle of reducing waste, reusing and recycling resources and products is often called the "3Rs." Reducing means choosing to use things with care to reduce the amount of waste generated. Reusing involves the repeated use of items or parts of items which still have usable aspects.
Answer:
I personally think they should reduce it from 6 feet to 3 feet because: Normally we stay 6 feet apart in case someone sneezes or coughs,(In schools also, not just in public), but there is no need to stay that far away; 3 to 4 feet is enough. Plus, in schools, friends want to socialize more, but that is not easily done when you are 6 feet apart. And, you do get tested a lot if you go to school, so if someone has virus symtoms, they probly will stay home and not go to school.
Hope this helps, and have a good day.
