To protect the äina, many people practice the three
Rs of conservation. They recycle aluminum cans,
paper, and glass. They reuse paper as scratch pads and
line garbage pails with plastic grocery bags. Some re-
duce their use of energy and materials through energy
conservation and careful maintenance to make things
Apply the three Rs to yard trimmings and leftover
food, and you have composting—an economical way to
reduce solid waste, reuse organic materials, and recycle
nutrients as a soil conditioner. Composting is about be-
ing good caretakers of our environment.
It’s in the bag
In order to estimate how much you threw out last week,
gather one day’s garbage from your household. Weigh
on a bathroom scale or estimate by comparing to a known
weight, like a 20-pound sack of rice. Multiply by seven,
and you have the amount of garbage produced by your
household each week.
Look at what’s in your garbage.
Any recyclable plastic or aluminum
containers or old newspapers? Take
these to be recycled. See any food
stuff – banana peels, fuzzy leftovers,
coffee grounds – or yard trimmings?
These materials are easy to compost.
When you remove the recyclables, 20
pounds of garbage is often reduced
to as little as 5 pounds.
