According to the attached article, Americans use about 13 billion pounds of paper towels each year.  Add in the use of toilet tissue, facial tissue, and paper napkins, and you’re looking at a huge volume of single-use paper products in landfills and sewage treatment plants.  In addition to the impacts of paper disposal in landfills (including producing methane as the paper decomposes), large areas of virgin forest in Canada are harvested each year to produce these throw-away items.  The article has a link to information on which products are most sustainable (based on use of water for processing, chemicals, and effect on forests).  The best thing is to reduce your use of these items.  When you do use them, look for brands made with recycled paper and use the smallest amount needed for that job.  It may take some experimenting to find the brands that work for you.

One good way to reduce food waste is to learn proper storage methods for each item to preserve the quality and flavor as long as possible.  This article provides a lot of information on produce items that should not be stored together, as some types may have a negative effect on the quality of the others.  Those who are cooking aficionados may disagree with the statement that most fruits and vegetables should be stored in the refrigerator, and you are welcome to disregard those instructions.  As an example, tomatoes retain better flavor if never refrigerated; however, if you are more concerned with how long they keep, you may choose to store them in the refrigerator anyway.
