The ozone layer absorbs ultraviolet radiation that can be very harmful to all forms of life. In 1974, however, scientists discovered that chlorofluorocarbons (CFCs), a chemical used in aerosol sprays, refrigerants, and the creation of synthetic materials, break down when they enter the stratosphere, and produce a chlorine atom, which then contributes to breaking down the ozone layer. In 1985, British Antarctic Survey scientists discovered a massive hole in the ozone layer above Antarctica.
Kimberley-Clark Corporation is the largest tissue-product manufacturer in the world, producer of well-known brands including Kleenex, Scott, and Cottonelle. It is no surprise that Kimberly-Clark is also arguably the leading consumer of wood-fiber. However, before 2009, Kimberley-Clark continued to take 90% this wood-fiber from unsustainably managed forests, most notably the ancient Boreal Forest in Canada.
