contentArray[0]="Protect your skin. Over 89% of the chemicals in cosmetics haven't been tested for safety, so choose chemical-free alternatives instead."
contentArray[1]="Lower your daily dose. The average woman is exposed to 168 chemicals from cosmetics every day. Reduce your risk by choosing chemical-free alternatives."
contentArray[2]="Free yourself from fragrance. Chemical phalates, which can disrupt the hormonal system, masquerade under the term &ldquo;fragrance,&rdquo; showing up in some 70% of personal care products."
contentArray[3]="Learn to read the label. Products made from organically grown ingredients can be labeled organic even if they contain chemicals. Watch out for parabens, phalates, fragrances, and other synthetic chemicals."
contentArray[4]="Steer clear of chemicals. Parabens, phalates, and other synthetic chemicals found in conventional body care products accumulate in our tissue over time, disrupting the hormonal system."
contentArray[5]="Chemicals in body care products don't just wash away. Those we can't absorb flow into our wastewater system with every bath or shower, eventually ending up in our lakes and oceans where they harm fish and reptiles."
contentArray[6]="Your pores act like a sponge, absorbing anything you put on your skin. Watch out for propylene glycol — it shows up in over half of all body care products and is designed to alter your skin's cellular structure so other harsh chemicals can penetrate more easily."
contentArray[7]="Keep your t-shirt toxin free. Choose an organic cotton tee over one made from conventionally grown fibers, and you'll prevent 1/3 lb. of pesticides from entering our environment."
contentArray[8]="Pick pesticide-free jeans. It takes 2/3 lb. of pesticides to make a single pair of conventionally grown denim jeans. Keep these toxins out of the environment by choosing organic cotton instead."
contentArray[9]="Sleep chemical free. A set of queen-sized sheets requires more than a pound of pesticides to produce — using organic sheets keeps these chemicals out of the environment and off your skin."
contentArray[10]="Conventional cotton requires chemicals. It takes over 13 lbs. of pesticides, herbicides, and defoliants to produce a single acre. Choose organic cotton and help keep these contaminants out of our soil, air, water, and food."
contentArray[11]="Five of the nine main pesticides used on cotton are known to cause cancer. Limit your exposure to these dangerous chemicals by wearing organic cotton instead."
contentArray[12]="Pesticides harm more than people. Drift from pesticide spray can contaminate groundwater, kill beneficial insects, and destroy microorganisms in the soil."
contentArray[13]="Glutens aren't good for everyone. One in thirty people suffers from a gluten intolerance. If you have problems with constipation, diarrhea, or irritable bowel syndrome, try going gluten-free."
contentArray[14]="Nearly 2 billion people worldwide are deficient in zinc, a critical antioxidant that helps boost immune function and prevent free radical damage. Don't forget the zinc."
contentArray[15]="Soy products may not be as healthy as you think. A single glass of soymilk exposes you to a level of plant estrogens that could damage your thyroid function, while products like soy dogs and protein drinks have been linked to hormonal, reproductive, and digestive dysfunction."
contentArray[16]="Conventional farming practices overwork the soil, rob it of key nutrients, and produce fruits and vegetables that lack vitamins and minerals. Eat an eco-friendly organic diet, for your health and the environment."
contentArray[17]="Factory farms are big polluters. Producing an average of 200 million lbs. of excrement every year, these farms contaminate our soil and groundwater with synthetic hormones and antibiotics."
contentArray[18]="Leave polyester in the past. As a petroleum-derived product, polyester contributes to the depletion of our nonrenewable fossil fuel supply and to our reliance on imported oil."
contentArray[19]="Polyester production damages our environment. It not only contributes to global warming by releasing carbon dioxide but also pollutes our air with lung-damaging nitrogen and sulfur oxides, particulates, carbon monoxide, and heavy metals."
contentArray[20]="Opt for nonacrylic fabrics. Like polyester, acrylic is an unsustainable petroleum product. It also poses health risks for acrylic fiber workers, who are exposed to acrylonitrile, a probable carcinogen."
contentArray[21]="Soda bottles get a second life as recycled fleece fibers. According to the U.S. Environmental Protection Agency, demand for recycled PET (polyethylene terephthalate) fibers used to make fleece vests, jackets, and blankets currently exceeds supply. So keep recycling!"
