   Buying in Bulk Saves Money
   We’re not just talking about buying giant boxes of food a warehouse store. (Although, if you eat that many Cheerios in a month, it can save you money.) We’re talking about the bulk bins at your local grocery store, where you can buy everything from rice, beans, flours, and spices to cereals, nuts, dried fruits, and pastas.
   You can save serious money shopping from these bins—10 to 30 percent off prepackaged prices.

2. Less Trash
   Compare the packaging of 10 cans of kidney beans to one bag. Or three 10-ounce boxes of cereal (three cardboard boxes and three un-recyclable plastic liners) to one bag and a twist tie. You can also reuse your bulk bin bag and twist tie to reduce your waste even more.
   If you’re super-attached to your old cereal boxes, save them and place your reusable bag inside.
3. Less Goes to Waste
   When you buy from the buy bins, you can buy the exact amount you need, so less is likely to spoil and go to waste.
4. Food Often Tastes Better
   Canned beans, for example, are more convenient, but once you get into the rhythm of pre-soaking beans and cooking them the night before, you’ll find beans from the bulk bins taste much better. They harbor none of the metallic aftertaste found in canned beans.
5. A Chemical Found in Most Canned Foods Is Linked to Cancer
   Unbelievable as it sounds, it’s true. Most food and drink cans are lined with a plastic resin that contains a chemical compound called bisphenol A (BPA). Due to a growing concern about the harmful health effects of BPA, it is being banned from baby bottles in Canada and many plastic-bottle manufacturers are voluntarily phasing it out of their products. The makers of cans, however, have not felt the wrath of consumers yet, so most plan to continue using it.

You don’t mess with the mama bear. That’s what my husband says when I get angry about an issue that could adversely affect our children. It’s also a major reason there is a rising public outcry over bisphenol A, or BPA, for short.

What Is BPA?

BPA is a chemical compound found in most plastic baby bottles, clear plastic sports bottles, infant-formula cans, drink and food cans, plastic utensils, dental sealants, hospital incubators, dialyzers, and more. It’s also linked to a number of health problems, including (but not limited to):

• Infertility
• Breast cancer
• Prostate cancer
• Insulin resistance (a common precursor to Type II Diabetes)
• Early puberty
• Chromosomal abnormalities that can cause miscarriage and birth defects

BPA is so widely used that even those who compulsively avoid BPA-containing products are exposed to it. BPA’s annual production exceeds a billion pounds. It is found in waterways, sediment, estuaries, household dust, and air. In humans, it is found in breast milk, saliva, urine, cord blood, and amniotic fluid. Many researchers say even low level doses of BPA can have a negative effect on developing systems. So, as with most toxins, BPA is of most concern to pregnant women, infants, and very young children.

If BPA Is Potentially Harmful, Why Is It Used at All?

BPA is added to hard plastics to make them less likely to shatter. Anyone who’s ever dropped and broken a glass in the sink is likely to see the merits of a shatter-proof material. In canned foods and drinks, BPA is used as a liner to prevent the ingredients from reacting to the metal in the can.

What’s Being Done About BPA?

Both the U.S. Federal Drug Administration and European Food Safety Authority insist that BPA is safe in the levels that a typical adult, child, or infant consumes. Their Canadian counterparts at Health Canada feel differently, however, and say it may pose a risk to infants. They suggest reclassifying BPA as “toxic” to human health and the environment. Canada is moving to ban BPA from baby bottles and other infant products.

In the U.S., BPA remains unregulated and the FDA is unlikely to take any action. Consumer demand, though, is driving change. Many of the most popular makers of baby bottles now offer BPA-free plastic and good old-fashioned glass bottles. Nalgene, the makers of clear plastic sports bottles often used by hikers and other cyclists, are promising to offer a BPA-free version soon too. And stores like Wal-Mart and Toys ‘R Us are demanding alternatives from their suppliers. (People tend to get angrier when babies’ health is involved, so traction on removing BPA from canned food and drink liners is going slower.)

After a series of fits and starts and intense lobbying by the Save the Plastic Bag Coalition (I kid you not, this is a real organization), the Los Angeles City Council voted to ban plastic bags from grocery and other stores. The ban is slated to go in effect by July 2010 if the state of California does not move forward with plans to require stores to collect a 25-cent fee on each plastic bag a customer requests.

The news comes on the heels of a much weaker plan voted on by the Los Angeles County Board of Supervisors, which voluntarily asks stores to encourage shoppers to bring their own bags.

Coastal Communities Happy, Bag Industry Sad

The Surfrider Foundation, Heal the Bay, and many neighbors in L.A.’s coastal communities and beyond support Wednesday’s move by the council. They say that ubiquitous plastic bags clog storm drains, litter city streets and beaches, harm wildlife, and add to an ever growing landfill.

Opponents, which include makers of plastic bags and the California Grocers Association, say the ban will have a devastating effect on the region’s packaging companies.

More Cities Poised to Ban Plastic Bags

San Francisco has already enacted a similar ban on plastic bags. Stores still offer free bags—usually paper, sometimes recyclable or compostable plastic. Based on anecdotal evidence, more shoppers bring their own bags. The cities of Malibu, Manhattan Beach, Santa Monica are also in various stages of plans to reduce plastic shopping bag consumption.

Most of the San Franciscans we’ve talked to support the plastic bag ban. Sure, it can be a pain to remember to bring bags to the store. But while paper or cloth bags are bulkier and take up more closet space, they are also more durable and hold more items than the old plastic bags. Overall, it’s good to treat bag as a commodity that we value. It encourages everyone to reduce, re-use, and recycle.

Here’s something the dry cleaning industry doesn’t want you to know: You don’t need them. Really. Most items in your closet, even the ones labeled “dry clean only” are hand-washable in mild detergent. I know. I’ve tried it myself on suits for work, wool sweaters, silk shirts, and more. Over the course of a year, I easily save $200-$350 just skipping the dry cleaner.

Save Even More Compared to “Green” Cleaners

I save even more if you compare what I’d spend at a “green” dry cleaner. I tried one once. It cost me $20 compared to the $6 at my standard cleaner, and it shrank my sweater. Good thing 3/4-length sleeves are “in” right now! Though, in all fairness, they did warn me that their environmentally friendly method has a tendency to shrink woolens.

Sure, dry cleaning has its immediate benefits, namely, someone else is doing your washing and pressing. But when you take the economic cost to you and the environmental impact (lots of non-biodegradable plastic bags and wire hangers in the landfill, toxins released into your home and our waterways) and compare it to a little extra work on your part, the choice is clear.

With companies like Clorox putting out product lines endorsed by the Sierra Club, should we be concerned about where all this “Go Green” is going?

Back in January 2008, the Sierra Club first announced its partnership with Clorox and the Green Works line of household cleaners—the first new line from Clorox in 20 years. While some consumers remain skeptical that the line is as green as it claims (phosphorus and bleach-free, with 99 percent natural ingredients like coconuts and lemon oil), the Sierra Club says they have fully investigated the line’s “green”ness and are happy to back the products.

But Clorox isn’t the only big-name company getting in the game, Colgate-Palmolive is currently promoting its own line of Eco-friendly, phosphorus-free cleaners, SC Johnson claims its recent Greenlist reformulations have removed 61 million pounds of volatile organic compounds (VOCs) from products including Windex, Pledge, and Fantastik Orange Action, and the list is growing steadily.

Whether you’re painting or just passing by a recently painted surface, the smell is unforgettable: strong, deep, “chemical-y,” often lasting for days. Paint fumes are caused by something called volatile organic compounds (VOCs), a major source of ozone creation and indoor air pollution. It’s also a major reason I’m willing to live with a wall color I hate longer than anyone should have to. Fortunately, consumer demand for no- and low-VOC paint is growing, and so are the choices.

You can buy no- and low-VOC paints online, at green building suppliers, and at most major paint retailers (including The Home Depot, which began offering its Freshaire Choice line this spring).

How “Natural” Differs from No- or Low-VOC

No- and low-VOC paints fall into two basic categories: those made with synthetic ingredients and those made with natural ingredients such as water, clay, bee’s wax, milk protein, plant oils, and mineral oils. (The latter are often referred to as “natural paints.”)

No-VOC (also called zero-VOC) and low-VOC paints made with synthetic ingredients more closely resemble the performance of traditional polluting paints (durability, consistency) and offer a wider variety of finishes (flat, eggshell, satin, semi-gloss) than natural paints. They cost less than natural paints—typically $30-$40 a gallon compared to $40-$60 or more a gallon—but more than standard paint, which can cost as little as $20 a gallon. You’ll also find no- and low-VOC paints at more retailers.

Why Choose No-VOC over Low-VOC?

The difference between no-VOC and low-VOC is not as simple as you’d think. According to EPA rules, a paint may be labeled no-VOC if it contains less than 5 grams of VOCs per liter. That means some no-VOC paints have no VOCs, but some do.

Kelly Moore’s Enviro-Cote, for example, contains 15 grams of VOCs per liter, even though it’s labeled no-VOC. While I myself don’t consider it a true zero-VOC paint, it’s still quite low when compared to traditional paint base, which can contain 100 grams or more per liter.

Low-VOC paints contain a lower amount of VOCs than traditional paints do (less than 200 grams per liter, under EPA rules). If you’re looking to reduce indoor air pollution, it’s best to go with a no-VOC paint.

Beware: Color Tints Can Add VOCs

Color tints, which you’ll most likely be using, can add even more VOCs, so check that your supplier uses no-VOC tints.

Last week we wrote about common ingredients in sunscreens that can bleach our coral reefs, where people swim and snorkel. Consumer advocates at the Environmental Working Group (EWG) also warn us about potentially unhealthy ingredients in sunscreen and other personal care products.

Yet even when armed with lists of ingredients to avoid, it can be a little overwhelming to decipher labels at the store. It’s tempting to take relief in the FDA and personal care industry’s claims that the ingredients used are of no significant harm. That may be the best route. But a growing number of consumers want to better educate themselves on the choices they make.

Here are quick tips you can use to read (and finally understand!) your sunscreen and other personal care labels:

Active v. inactive/other ingredients:
“Active” ingredients are the components that do the real work. In sunscreens, that means the chemicals (avobenzene, zinc oxide, etc.) that protect your skin from the sun’s rays. “Inactive” or “other” ingredients include everything else, from fragrance and preservatives to the components that give sunscreen its lotion-y feel.

UVA and UVB protection:
SPF (sun protection factor) is only part of what you need to know. Some ingredients protect against UVB rays, which cause skin burn, and some others protect against UVA rays, which  have been linked to wrinkles and skin cancer. See EWG’s report for details and specific brand recommendations:
http://www.ewg.org/sunscreen/

The order:
Ingredients are listed in order, from greatest to least: your sunscreen contains the most of the first item listed and the least of the last one.

Less is more:
Fewer ingredients mean less potential to come in contact with harmful ingredients. If you can pronounce the ingredients that’s even better. Some conscious companies now explain in layman’s terms what purpose each ingredient serves.

Watch out for butyl paraben:
What’s suspected to be harmful to the coral reefs is not necessarily suspected to be harmful to humans, but butyl paraben appears on both lists. It’s used as an antifungal.

Look for “-yl”:
This is not a foolproof method as it’s merely a chemistry term, but it’s good for a quick scan. Sodium lauryl sulfate, methyl paraben, butyl paraben, butylated hydroxytoluene are just a few “-yl” containing ingredients you may wish to avoid.

12 ingredients to be aware of:

See how your sunscreen stacks up:
The Environmental Working Group’s Skin Deep Database contains detailed ingredient information on more than 25,000 personal care products. If your brand is not in the database, you can enter its ingredients and see whether it contains any of the 50 chemicals of concern.

I think it’s super cool that my new compact fluorescent light bulbs (CFLs) give off as much light as my old 60-watt incandescent bulbs, yet they use just 13 watts and last years longer. It speaks to both my cheap side (in lower electricity bills, fewer bulbs bought) and my eco side (less electricity used often means less coal burned).

What’s not so cool is the thought that, because CFLs contain mercury that can leach into our waterways and groundwater, I may have to schlep out to the hazardous waste dump to dispose of them when they eventually burn out.

Fortunately, as CFLs catch on, there are more places to recycle your used bulbs. Swedish retailer IKEA now collects used CFLs at its 34 U.S. stores and manufacturer Osram Sylvania offers a mail-in program. The Home Depot, many local hardware stores, and some Wal-Mart stores also accept bulbs. Just make sure that you seal your used CFLs in a zip-lock type plastic bag and handle them with care. You don’t want a bulb containing mercury to break in transit.

For years we’ve been told by doctors to wear sunscreen to protect ourselves from the cancer-causing ultraviolet rays. Now it seems, this protection for humans may come at a cost. According to a report published in the National Institute of Environmental Health Sciences journal Environmental Health Perspectives, chemical ingredients found in most sunscreens can cause bleaching in coral reef and are accumulating in fish and other aquatic life.

An estimated 6,000 tons of sunscreen ends up in coral reef areas where people swim and snorkel. And because 60% of the world’s coral reef is threatened by rising sea temperatures, pollution, and excess UV radiation, the sunscreen issue is worth further study and action.

Here are a few ways you can do your part to limit these chemicals in our oceans and still protect yourself from the sun:

1. Wear a long-sleeved rash guard (swim shirt) so less skin is exposed and less sunscreen is needed. You can find UPF-rated clothing at surf shops or online at Coolibar and Athleta.
2. When not in the water, stay in the shade, so you’ll need to reapply sunscreen less often. Bring a beach umbrella and wear hat.
3. Wear sunscreen with biodegradable ingredients. (This is already a requirement in some protected areas in Mexico.) Avoid sunscreen that contains Benzophenone-3 (Oxybenzone), ethylhexylmethoxycinnamate (Octinoxate), 4-Methylbenzylidene camphor, and Butylparaben.

Brands such as Alba Botanica, Badger, Burt’s Bees, California Baby, and Keys Soaps carry sunscreens that don’t contain the ingredients above and can be found at many natural foods stores. But buyer beware: none of the suggested brands come in an SPF higher than 30, which for those with fair skin, can be an issue.

Coming soon: our own biodegradable sunscreen field test.
