Natural dye

Colorful dyes have been used to gussy up fabric for thousands of years, and for most of that time it hasn't required synthetics. To this day, flowers, seeds, bark, leaves, even insects are the source material for natural dye. Unlike synthetic dye, which is primarily derived from petroleum, natural dye is renewable and biodegradable, and poses little to no health or environmental risk in production or disposal. Synthetic dyes are much more widely used, of course, because they can be easily and cheaply produced. And they can achieve a brightness that most natural dyes cannot. It's worth noting that low impact, or fiber-reactive dyes, are not usually natural, though they do have environmental benefits.

Word of the Day
   Drywall

If your home was built in the last 50 years or so, you're probably surrounded by the stuff. Give it a knock and you'll hear that familiar echo. Drywall is the most commonly used interior wall finish material today-having usurped those thick, plaster and lath walls that were ubiquitous until World War II. Also called gypsum board or sheet rock, it is made of paper-typically recycled, unbleached paper-over a core of gypsum, a mineral compound. Drywall made with either recycled or synthetic gypsum is a greener choice than that made with new, mined gypsum; synthetic gypsum is made from a coal-combustion waste product, so it reduces waste, saves energy, and averts the environmental damage caused by mining.
