The Pigment of Computer Paper
Have you ever wondered why paper is so white? When you see a fallen branch or tree and look inside, it is usually a yellowish white or even sometimes green. People prefer to work with paper that is extremely white, so their words can be seen better. A bleach is a chemical that removes colors or whitens, often via oxidation. This is what is used to make paper the color it is usually seen as today. When the page is completely bleached, it often lets the black ink stand out more then it would on a page of other color. This chemical can be found in all types of house cleaning materials, but just because it is found in the average home, does not mean it is particularly safe. Bleach harms the environment when it is leaked into water supply and depletes animal lives. If it is leaked into a small pond, it would not be surprising if all life in the pond died out. There have been many researches done to see bleach's effect on this planet, and they have noticed that for every use of bleach, there is an alternative method with another chemical or alcohol.
Thank God men cannot fly, and lay waste the sky as well as the earth. ~Henry David Thoreau
