# Soap

Buy bar soap instead of liquid soap.  The first reason is that disposable
plastic is nasty, and while bar soap usually comes in a cardboard box, liquid
soap always comes in a plastic bottle.  The second reason is that liquid soap
contains large amounts of water, while bar soap doesn't.  Water is heavy, and
transporting it with trucks over long distances is a source of pollution that
can be entirely avoided in this case.
