The Story of Stuff (Yours and Mine)
Now that the holiday gift giving frenzy is over, and resolution making time is upon us, it would be a good time to try to be more mindful of the amount of pure STUFF we accumulate, eco-stuff and otherwise.
When you have 15 minutes or so (now would be a good time!) click-on over to The Story of Stuff, a really neat, engaging little animation / movie that at the very least will getcha thinking about it all.

Water Without Poison: Avoiding Plastic-Bottled Water
The question over plastic products poisoning packaged food and water is one reason to avoid plastic water bottles. Although various mechanisms have been suggested for plastic byproducts leaching into bottled water (leaving bottles in hot cars, re-using plastic bottles), Snopes.com purports to have debunked these.
For the most part, however, bottled water is not local water; bottled water gets part of its cache by coming from far off exotic locals (Fiji Water, for example, or Perrier, or even simple Arrowhead water). The folks at http://www.thebottledwaterstore.com/ boast that they are "[y]our source for unique high-quality bottled water products from around the world." And that means its value as a "green" commodity is further degraded by the addition of the carbon and oil use from its long distance ride to the market shelf.

Coffee Tastes Better Green
Thankfully, however, I have managed to ratchet my Starbucks habit way down over the past year. Oh I still drink coffee everyday, but thanks to a serendipitous gift of a reusable mug last year, my growing green sentiment, and the realization of the budgetary effects of store-brewed coffee, I only occasionally indulge in a stop at the "coffee store."
Green Issues, Black Coffee
Coffee is an interesting beverage in many eco-respects, as it embodies several different green issues. Correcting even a few of the bad things about the way you get your caffeine fix can make a big difference.
The issues range from the use of non-recyclable paper cups and plastic lids, to where and how the coffee is grown; from your choice of brewing method to how you keep the java hot. Each separately can be a significant factor in the green-color of your coffee's history. But let's start with one easy one: the kind of cup you use.
Buy the Cup
I was given a gift of a Starbucks brand 16 ounce reusable travel cup last year for a holiday gift. I have used it every day, sometimes several times a day, ever since then.
Our friends over at the Bring Your Own Blog have already made the paper-cup point succinctly.
Which is Greener: Recycled Paper or Reusable?
There are several elements that must be considered to demonstrate that a reusable cup is better than a one-time use cup; most analysis take into consideration only one part of the multifaceted problem.
First is the embodied energy used in manufacturing the cup. A reusable cup will have more energy in its initial manufacture, and has to be washed, but over time it will save energy each over a similar number of paper or foam cups. One major factor is how the cup is washed: I rinse mine daily in warm tap water with a little soap; most studies assume the use of an energy hog dishwasher, albeit a relatively efficient energy hog as those things go.
On this basis, a reusable cup is relatively more energy efficient, at least if it is used repeatedly as intended.
Next is the issue of the resources used to create the cup. Plastic and foams come from oil. In generally, the fewer products made from oil, the better; whether you want to reduce the impact of oil drilling or think gas prices should be lower, less oil for cups is desirable. Paper cups, of course, come from trees, and in some cases a small percentage of post consumer recycled paper.
Then there is the disposal issue. Although paper cups may degrade over time, they take up landfill space in the meantime. And since many paper cups are, in fact, plastic coated, that degradation is not total, or quick. Neither plastic nor foam cups degrade in any reasonable amount of time (hundreds of years even in a landfill), and many spend time drifting around the landscape or floating around the ocean, where they kill wildlife.
Using an average of one disposable cup per day adds in the range of 25 lbs of solid waste to the landfill stream, and creates a larger pool of trash which can becomes "feral" and degrades the environment directly. (See, e.g., Report of the Green Restaurant Association and Report of the Starbucks Coffee Company / Alliance for Environmental Innovation Joint Task Force, p. 8-9.)
Finally, plastic and plastic coated food products have recently been implicated in all sorts of health problems, including reproductive defects in children born to women exposed to certain kinds of plastics. These plastics leach byproducts into our food, and into the environment for as long as they are around.
The Whole Story
Looking at the whole story, then, it is easy to see that the reusable to-go cup is a significant ecological improvement over one-use paper or plastic cups.
Reusable to-go cups also have a psychological advantage, too, by stepping away from the disposable mindset.
Which Reusable Cup?
So far the best reusable cup appears to be stainless steel. This metal is well known to be inert and resistant to just about anything you put in it. It washes up quick and easy by hand, and works equally well with hot and cold drinks. Many coffee outlets sell metal ones . . . to take it one step further, one can skip plastic water bottles too: One supplier of disposable cup and bottle replacements is the KleanKanteen company.
Plastic reusables are, at least, reusable; but since the use of plastic in food products is increasingly suspect, as noted above, a plastic mug cannot be recommended. Ceramic mugs have some of the lowest embodied energy, according to research studies, but for travel a steel mug is extremely durable and about the cleanest choice.
Paper, whether made from all virgin wood or some small percentage "post-consumer recycled content" still contains a lot of new tree material, and requires a reasonable amount of water and energy to make into each new cup, even with recycled content.
My stainless steel travel mug took a lot of energy to make, more than a few paper cups worth, certainly. But it's energy cost is spread out over hundreds of cups of coffee and years of use. And there is an additional benefit: I never throw it away (at least until it finally wears out), so it does not add to a landfill or pollute the local environment they way disposables do.
And yes, that cardboard cup almost certainly gets buried in a landfill somewhere. Even if you rinse the cup and toss it in your recycle bin, more likely than not this is not helping: Most paper products used for food are not recycled. Greasy pizza boxes and used paper cups are routinely plucked from the paper recycling by most companies and disposed of as simple landfill garbage.
Although plastic food containers can sometimes be recycled, and most plastic cups have a recycling number on the bottom, many many jurisdictions do not accept them, and few recycle the kind of foam from which foam cups are made.
Moreover, plastic cups get into the environment by accident too (or deliberate littering) and do not decompose at all. Instead they wash into storm drains, helping to clog them, and as often as not wash right out to sea.
It hardly seems like a big deal, but there is, after all, a lot riding on the cup from which you drink your coffee. And somehow that morning cup 'o joe just tastes better green.

Skip the Plastic! Let's Talk Reusable Cloth Bags . . .
Sounds simple minded, but take a look at the counter in the right-hand column. According to the folks at www.reusablebags.com, that is the number of plastic bags that have been used, and mostly tossed into the landfill or allowed to destroy marine environments, so far this year.
That's a lot. And the number is getting bigger. If you have 6-8 plastic bags from grocery shopping today, and another of two or three from other stores, and one for the thingmabobber from the hardware store and and and -- well it adds up!
Three reasons to bring your own reusable cloth bags:
1. Plastic bags are mostly made from oil. The folks at MidAmerica Energy explain this in detail here or by clicking their picture, above. The fewer plastic bags we use the less we need oil from the Middle East, the less fossil fuel pollution we create, and the less energy we use manufacturing and transporting the darn things in the first place.
2. Some plastic shopping bags can be recycled. Most are not. Less than 10% of plastic bags are currently recycled. Some city trash collections, even though they accepted numbered plastics, do not do plastic shopping bags.
3. Plastic ends up in the landfill, and does not decompose (paper can be recycled and does decompose. Cloth can be reused thousands of times). It is also a notorious killer of marine animals, being washed down the storm drains and into the oceans.
Dealing With The Would-Buts
I would use cloth bags, but:
. . . I can never remember to bring them. Simple: Leave a nest of 4 or 5 bags in the trunk of your car, or the bike trailer you use for groceries. Put them all inside of one and roll 'em up. When you empty the bags in the house after shopping, put them *right* back in the car. Then they are always handy.
Bringing shopping bags has gotten to be so easy, that we take our TJ bags -- and reusable bags we have received elsewhere -- in to shop just about everywhere now. It may just be *one* little plastic bag -- but take a look at that counter over there, spinning by, one little bag (your little bag!) at time.
By the by, the cloth-bag habit is a good one to start now. Several cities have banned plastic shopping bags outright, and many more are looking at the idea seriously.
A word of warning about reusable bags, though: Be sure to save some for shopping. They are so handy, and so easy to grab, that they get used for all sorts of transporting jobs -- and you can and that all your shopping bags are otherwise engaged!

How to Get Off Your "Would But"
and Start Doing Something
You know you should do it (whatever green thing “it” is) and you would but, well this thing and that thing and the other thing really make it impossible for you to do right now.
Welcome to Stage One Denial.
I’ve been there; every time I stop doing some green thing for awhile, I go through it again to get started. Breaking through Stage One Denial -- the "would-buts" -- is the hardest part of doing the green thing, at least sometimes.
An Example: Bike to Work Day, Just Today.
Take, for example, the green goal of riding a bike to work. Last summer I rode nearly every day to work. It was hot, but bearable. I got to wear summer clothes to work (shorts, polo shirt) so it was a fairly comfortable bike drive.
But the fact that I had to carry a laptop to work every day changed the ride. I was nervous carrying it unpadded in a backpack. (The computer case I had weighed a great deal, so I did not want to carry it on the bike.) And the backpack made me really hot. Although I rode most days in the summer anyway, the laptop-in-the-backpack became my “would-but” for the fall semester.
In the fall semester, without a way to carry my laptop conveniently, I rode a car to work every day. I would have driven my bike, but carrying the laptop was a problem. See how this works?
Over Christmas I received a really cool Jandd pannier bag. Folds up to look like a canvas briefcase, has a padded holder for a laptop, and a built in waterproof cover(!)
This week, my laptop and I drove a bike to work every day.
How about you?
What’s your bike-riding “would-but?”
For most of us it is one of these top ten:
1. “I don’t have a bike.”
2. “I have a bike, but I haven’t ridden it in years.”
3. “I’m scared of the cars.”
4. “I have to work in dress clothes, like a suit or high heels.”
5. “I work too far away.”
6. “I have to carry stuff to work.”
7. “I have kids to pick up.”
8. “The weather is too severe.”
9. “There is nowhere to park a bike when I get there.”
10. “I have bad knees/back/balance and can’t ride.”
I have used at least seven, maybe seven and a half of these personally.
We’ll deal with these Top Ten Would-But excuses in future posts. For the moment it is enough to recognize a "would but" excuse for what it is – a temporary obstacle to be overcome. And once overcome, most of these would-buts seem terribly insubstantial.
In general, though, the top suggestions for more bike driving are to get a good used cruiser bike if you don’t own one (try www.freecycle.org for a potential free bike!), or clean yours off and get it out of the garage! Drive your bike on weekends from time to time to get back in the groove; find a “Road Cycling” course online to help you understand and deal with the driving a bike instead of a car for transportation -- versus riding a bike for fun only.

IDEA: Green Your Brain!
What is wanted is a simple but complete change of mindset that allows one to make green choices without particular sacrifice, and as second nature.
The culture of waste and despoliation of the planet has been in place a long time, however, and such a fundamental change can be frightening, even daunting.
Consider: At my house, according to the electric company, we've managed to conserve 90% (yes, ninety percent) on our electric bill last year. Even with the hottest summer on record this year and the AC running 24/7, we are on track this year to "save" 50% of the electricity we would have used in the past.
We have solar cells.
Although Pasadena gets nearly 70% of its electricity from coal, ours is 100% renewable, clean and green. No sacrifice. No actual conservation. No big deal.

Five Percenters, Changing the World
Turns out, at least a few folks have invented a term for it, calling it the "Five Percent" approach.
Imagine if every single person on the planet invested 5% of their
energy in working toward a better self and a better world. I decided to try it,
since it's something I can do not just once, but every single day. These are the
stories of the little efforts I'm making while living my ordinary life. I'd love
to meet you along the way!
