Nutrients for our Bodies:
Carbohydrates
Carbohydrates are sugars
 Main supply of energy for your body to

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
