Three principles that truly describe being green are "Reduce" "Reuse" and "Recycle" which apply also to individuals where one uses only what's necessary, avoids consuming excessively, ceases the consumption if it's not a necessity and reuses or recycles when possible.
The three R's - reduce, reuse and recycle - all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space, and energy.
the three R's save land and money communities must use to dispose of waste in landfills. Siting a new landfill has become difficult and more expensive due to environmental regulations and public opposition.
