Alternatives To Wood Pulp
See also: Tree-free paper and Fibre cropToday, some people and groups advocate using field crop fibre or agricultural residues instead of wood fibre as being more sustainable. However, wood is also a renewable resource, with about 90% of pulp coming from plantations or reforested areas. Non-wood fibre sources account for about 5-10% of global pulp production, for a variety of reasons, including seasonal availability, problems with chemical recovery, brightness of the pulp etc. Non-wood pulp processing requires a high use of water and energy.
Nonwovens are in some applications alternatives to paper made from wood pulp, like filter paper or tea bags.

—Connie J. Downey (b. 1934)
“Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.”

“Cats seem to go on the principle that it never does any harm to ask for what you want.”
—Joseph Wood Krutch (1893–1970)
“Commercial jazz, soap opera, pulp fiction, comic strips, the movies set the images, mannerisms, standards, and aims of the urban masses. In one way or another, everyone is equal before these cultural machines; like technology itself, the mass media are nearly universal in their incidence and appeal. They are a kind of common denominator, a kind of scheme for pre-scheduled, mass emotions.”
—C. Wright Mills (1916–62)
