Paper vs. Plastic
Both deplete natural resources
Both take lots of resources and take a
toll on the environment throughout their
life cycles
Better to use a reuseable bag
If you have to use paper or plastic make sure to reuse and recycle!
Plastic Bottle Life Cycle
Recycled, sorted, shipped to plastic reclaimers, processed and made into
other products like clothes, benches,
new plastic products
