Examples of SUSTAIN
 
"Pushing fallen leaves into garden beds to insulate plants and nourish the soil will also shelter hibernating insects that, in turn, will sustain ground-feeding birds. It's much better for the ecosystem—and easier for the gardener—than bagging them up and sending them to a landfill." — Jessica Damiano, The Chicago Daily Herald, 12 Oct. 2025
