Finally, Maria made sure that many of the items in the store could be easily recycled. She set up well-marked collection containers to make it easy for shoppers to participate in the market's recycling program.

The materials needed to make either bag come from our natural resources.
Paper comes from wood, which comes from trees, which grow in the earth's soil.
Plastic is made from petroleum, also known as fossil fuel. The trees needed to make paper are considered renewable resources. That means more trees can be planted to take the place of trees that are cut down to make paper and other products. But, trees take many years to replace because they grow slowly. Once paper is made, it can be recycled and used to create more paper goods.
