a cyclical understanding.

reading Dam Nation: Dispatches from the Water Underground i'm reminded that nothing is ever truly disposed of, nothing really goes away. matter simply changes form. industry, agribusiness and our water infrastructure are all designed on a linear model, when we live within a cyclical system. how different things would be if we took into consideration the full life cycle of every resource and every element.

modern toilets are only one illustration of a forgetful, wasteful model. when cured correctly, human urine and feces can become a nutrient rich humus for growing food, or simply returned to the soil for positive impact. instead, massive amounts of clean, potable water are used in the US to flush them away, and massive amounts of energy and chemicals are used to prepare this sewage for dumping in waterways.

Dam Nation chronicles alternatives, from individual composting toilets to centralized collection systems. As Laura Allen writes "A system that enforces [waters] thoughtless use and waste necessarily inculcates a disregard for own lives requirements." Here are some resources for finding out more about ecological sanitation.

urban composting.

San Francisco (considered the 8th greenest city in the world) produces a 5 ft. high football field of trash a day. sadly, as much as forty percent of that waste is actually organic matter that could be diverted from the waste stream. (when organic matter is placed in landfills it produces methane, a major source of global warming. but when organic matter is composted it becomes nutrient rich soil.) worm bins are perfect for composting food scraps in an urban environment because they can be stored inside, allowing us to recycle our waste on site. worm bin systems are also easy to maintain and if worms are not overfed, bins are odorless.

supplies

-many counties offer discounts on worm bins, pricing them at about $40. if your county does not provide worm bins at cost, you can purchase
the deluxe Wriggly Wranch Worm Bin for around $100 online.
-for a more inexpensive system, worm bins can be constructed from wood or created by drilling 1/4 inch ventilation holes in a plastic storage bin. instructions for building each type are available here.
-1 lb. of red wriggler worms cost around $20. local environmental and gardening organizations, as well as government waste management sites, often list local sources for worms.

starting out
-once you have all of your supplies, shred enough newspaper to fill your bin 3/4 full. sprinkle or spray the paper with water until it is damp, but not dripping. place your worms and a handful of chopped scraps in the bin on top of the bedding and cover with more shredded paper.
-leave the bin for a few weeks in order to allow the worms to get adjusted. once you see that the food has changed and is being eaten, you are ready to add another handful of food.

maintenance
-chop food scraps into 2-3 inch pieces before placing them in the bin.
-avoid meats, dairy, oil and cooked food.
-the bin should be damp at all times. use a spray bottle to dampen the newspaper if it is drying out or add dry newspaper if it seems too damp.
-alternate sides for feeding in order to evenly distribute food.
-as the worms reproduce you'll be able to feed them more scraps more often. it may take a few months before the worms establish themselves and can eat 1 lb. of food a day.
-the worm castings you'll harvest are nutrient rich and they can be used to fertilize and inoculate soils. always dilute castings by mixing with 5 parts soil or water for a "tea."

guerrilla gardening.

in his book "Guerrilla Gardening" David Tracey writes: "Every bit of land you see around you, from the lawn across the street to the street itself to the schoolyard at the end, is used in accordance to a decision made by someone. The decision may not have involved you at the time, but you're involved now because it makes a difference in the kind of world you live in and react to every day. If land matters, so too do all the things that may or may not grow on it."

no space is neutral. and no space is apolitical. urban (and suburban) design both signify and affect. when city planners and developers use land for parking lots rather than community gardens they are making decisions that have an impact beyond that one block of pavement. but we can also have an impact on our landscape. simply put, guerrilla gardening is "gardening public space with or without permission." (Tracey) it is recognizing that all sites have the potential to carry life. it is imagining cities that can feed themselves. it is engaging with our local environment (including the concrete and the fences.) it is autonomous action and community care.

guerrilla gardening re-defines what is natural and re-invents what is public.

if you're planning on doing some guerrilla gardening of your own, here are some things to keep in mind:

-when planting edibles, be aware that the soil in vacant lots often contains toxins. if you don't know the long history of that particular site it is best to plant in raised beds or use containers for growing vegetables and herbs.

-when not planting edibles, research what plants are native to your area. native plants will fair better and non-native species can easily become invasive.

-guerrilla gardening can be done in the daytime. unless you're messing with a site that is frequently visited by regular landscapers, or under surveillance, most people will assume that you are supposed to be there with trowel in hand. try to dress like a city worker and act like you belong.

-guerrilla gardening can be done almost anywhere- along fences, up poles, down alleys, in abandoned cars. if a site is inaccessible, you can always throw "
seed bombs" by molding soil, clay and seeds together.

-topsoil can often be found for free on Craigslist and seed exchanges exist in many areas (as well as online.)

reusable.

according to E Magazine 6.5 billion tampons and 13.5 billion sanitary pads, plus their packaging, ended up in landfills or sewer systems in 1998. in addition to the waste they produce, most disposable menstrual products are manufactured using bleach, increasing dioxin pollution to the air and dioxin exposure with use. these three options are safer for the environment and your health.

-luna pads and glad rags are washable pads that come in a variety of sizes and can last for years. both companies offer organic cotton options (according to the Sustainable Cotton Project, 25% of all the pesticides used in the U.S. are used on cotton crops.) if you're handy with a sewing machine, you could also make your own.

-jade and pearl sea sponges are natural, reusable tampons. they are sustainably
harvested and for $10 you receive two- enough to last a year. simply rinse them out every few hours and in between periods they can be disinfected with a few drops of tea tree oil.

-the diva cup is made from hypoallergenic silicon and can be worn for up to 12 hours before being emptied and rinsed. although these are the most expensive option, they are designed to last for ten years.

less waste. less money going to corporations that hurt women's health. and a greater connection to your body.

safer cleaning.

a recent article in the San Francisco Chronicle reveals that many common commercial cleaners (including Simply Green) contain the chemical EGBE that has been linked to fertility disorders. although there are many environmental cleaning products on the market now, it is always cheaper and more sustainable to make your own. below are some tips and recipes I found while researching homemade alternatives.

-all purpose spray cleaner
1 cup white vinegar

1 cup water
combine in a spray bottle and use for surfaces.

-toilet bowel cleaner
use undiluted vinegar

-abrasive cleaner
sprinkle baking soda onto a damp sponge for bathtubs, sinks and refrigerators. for tougher grime, make a paste of baking soda and water, apply to the tub or sink, and allow to stand for 10 to 20 minutes.

-glass cleaner
club soda is an effective glass cleaner. or try this recipe:
1/4 - 1/2 teaspoon non-toxic liquid detergent
3 tablespoons vinegar
2 cups water
put all the ingredients into a spray bottle, shake it up a bit, and use as you would a commercial brand.

-bleaching
lemon juice acts as a natural bleaching agent. put lemon juice onto white linens and clothing and allow them to dry in the sun. stains will be bleached away.

-removing rust
sprinkle a little bit of salt on the rust, squeeze a lime over the salt until it is nicely soaked in lime juice. leave the mixture on for two or three hours. use the leftover rind as a scrubber.

-furniture polish
1/2 teaspoon oil, such as olive (or jojoba, a liquid wax)
1/4 cup vinegar or fresh lemon juice
mix the ingredients in a glass jar. dab a soft rag into the solution and wipe onto wood surfaces. cover the glass jar and store indefinitely.

-mold killer
2 teaspoons tea tree oil
2 cups water
combine in a spray bottle, shake to blend, and spray on problem areas. do not rinse.

-laundry powder

1/4 cup Washing Soda (not the same as baking soda. it is found in the laundry aisle of some stores)
1/4 cup Borax

1/4 cup grated natural soap

you can also mix these together in larger amounts and store for later use.


-fabric softener
add 1/4 cup of baking soda to the rinse cycle.

networks.

at the first US Social Forum last month, 10,000 people came to Atlanta to attend workshops addressing immigration, food sovereignty, health care, climate change, queer rights and hundreds of other social and environmental justice concerns. Naomi Klein calls such activism against oppressive economies and states "a movement of movements." Vandana Shiva believes it is "Earth Democracy," a practice which "connects the particular to the universal, the diverse to the common, and the local to the global."

in this time of both global information and global corporate control, we can understand the commonality of our causes. (coca cola contaminates local water wells in India->union leaders in coca cola plants in Colombia are murdered->the obesity epidemic in the US is caused in part by soft drink sponsorship of underfunded schools.) human rights and environmental preservation are now recognized as interdependent. but this "movement of movements" is not united by a single ideology. it is more organic than historical forms of activism, functioning as natural systems do. localized and adaptive, it is a network of people working to sustain life in their own communities.


when mapped, the dynamics of this "movement of movements" have often been compared by theorists to the internet. and the internet has done much to link the efforts of dispersed organizations and individuals. Paul Hawken writes "Webs are complex systems of interconnected elements that link individual actions to larger grids of knowledge and movement. Web sites link to other sites with more links to other sires ad infinitum, creating a critical, fluid mass of information that evolves and grows as needed- very much like an immune response. At the heart of all this is not technology but relationships, tens of millions of people working towards restoration and social justice."

there is, of course, great irony in this phenomenon. relationships are formed in the forums of a disembodied medium. technology is used to learn the skills (local plant identification, sustainable farming practices) common in pre-technology societies. computers used to help labor activist and ecologists educate and organize, are manufactured in low wage factories using toxic materials. and, like other common electronic devices, they
consume a large amount of energy with use and create hazardous waste in their disposable design. so here are some ways to minimize the environmental impact of our computers, while continuing to use them as tools.

-according to a variety of sources, including a New York Times article, laptop computers use less energy than desktops, LCD screens use less energy than CRTs and Macs use less energy than PCs. energy star certified computers can be found on this EPA website.

-setting your computer to sleep or hibernation mode when idling can save a lot of energy. an easy guide to changing your settings is available here. or you can download a free "Co2 Saver" program that will change the settings for you.

-you can locate places to recycle computers and other electronics on the Earth 911 website.

sustainable lives.

1. from "Days of War, Nights of Love" by the CrimethInc. Collective:

"The demand that radicals be free from hypocrisy, free from any implication in the system has the same effects as the Christian demand that people be free from sin: it creates frustration and despair in those who would seek change. Rather than seek to have clean hands, we should aim to make the inevitable negative effects of our life worthwhile by offering enough positive activity to more than balance the scales. This approach to the problem can save us from being immobilized by fear of hypocrisy or shame about our "guilt."

2. from "Arctic Dreams" by Barry Lopez:

"If there is a stage at which an individual life becomes truly adult, it must be when one grasps the irony in its unfolding and accepts responsibility for a life lived in the midst of such paradox. One must live in the middle of contradiction, because if all contradictions were eliminated at once life would collapse. There are simply no answers to come of the great pressing questions. You continue to live them out, making your life a worthy expression of leaning into the light.

3. Clea Duvall's video "It's Not Easy Being Green."


i believe that accountability is crucial. but i have also begun to understand that contradictions are a witness to life's complexity. if we abandon the idea of being "good" we may just become far more effective and creative people.

for the 4th.

i recently heard an interview with Paul Hawken, author of Blessed Unrest: How the largest movement in the world came into being. during this interview Hawken made the crucial observation that global warming is a new form of colonialism. we've all heard the statistics. how the US has 5 percent of the world's population but consumes 26 percent of the world's energy. or: on average, someone in the US uses 15 times the energy of someone living in the global south. but it is the citizens of the global south who will be most impacted by climate change.

i understand that global warming is a crisis that requires political agitation and corporate accountability. i also know how easy it is to be overwhelmed by the magnitude of this problem, to leave the work of change to a few activists and legislators. so here are some simple ways that we can lessen our impact, to weight those statistics towards something more equitable.

-
consider what household appliances are really necessary. this (british) table lists the average energy consumption of most.

-even though refrigerators use a large amount of energy there are ways to improve their efficiency. 1) clean the dust off the back coils with a damp cloth every 6 months or so. 2) move your fridge away from your oven or stove. 3) let food cool completely before placing it inside the fridge.

-even when electrical appliances are off, they still draw energy, an energy loss that composes 5% of your electric bill. to save energy unplug toasters, stereos, computers, etc. from outlets when you aren't using them, or plug everything into power strips that can easily be switched off when you leave.

-make sure your computer goes into sleep or hibernation mode when not in use. a free program for ensuring this can be found at
co2saver.snap.com.

-about 5% of all electricity used in US homes is used to dry clothes. if you don't have access to a yard or balcony, drying racks (as sobriquet67 suggests) are great for indoors and don't require much space.

-replace
incandescent light bulbs with compact florescent bulbs. you can calculate your savings for doing so here.

-some other steps towards home efficiency (for both renters and owners) include wrapping your heater in a water heater blanket, regularly cleaning filters in AC units, caulking leaky windows and putting rugs under door jams.

the US Department of Energy writes that "just by using the "off the shelf" energy-efficient technologies available today, we could cut the cost of heating, cooling, and lighting our homes and workplaces by up to 80%."
of course high energy use in the US is due to our patterns of consumption as much as our personal use of fuel and electricity. eating locally, choosing a vegetarian diet and avoiding packaged foods and goods are all ways to reduce your carbon footprint.

p.s. air travel is a huge contributor to global warming, though the pollution from flying is rarely addressed (i just learned that taking 1 cross country flight effectively canceled out an entire year of not driving.) so when traveling, taking the train is the most environmental option.

personal economies.

there are some in the U.S. who operate outside of the money system by choice (rather than circumstance.) who live as urban scavengers, subsisting on food saved from dumpsters and turning abandoned buildings into homes and collective squats. there are also a few rural communes that exist as completely self-sustaining communities, living off the electric grid and growing all of their own food. but both of these options require a fair amount of security to begin with. what about those of us who can not afford to completely drop out of this capitalist system (for reasons of finance or efficacy)? how do we circumvent this destructive economy from within?

deciding to buy as little as possible by making, trading, salvaging, and repairing is one way to create less waste. gift economies are another powerful tool. in addition to saving resources by recycling goods and bartering services, they also create
spaces of autonomy and cooperation. gift economies have existed in different forms and in many cultures long before capitalism was practiced, but here are a few ideas that challenge us to move beyond the role of passive consumers, to become active participants in local economies of exchange.

-beyond barter is a skills pool in L.A. when members sign up they list what skills they have to offer and how many hours a week they are available. services such as acupuncture, massage, computer repair and legal help are available. (there is an initial registration charge of $50 and then it's about $8 a month. but hey, if you start one in your city, you wouldn't need to charge a thing.)

-really, really free markets are now active in san francisco, nyc, philadelphia and carrboro, nc. once a month people gather in a central location with whatever they want to give away. everyone is welcome to take. the carrboro organizer's explain it this way:
"Because there's enough for everyone. Because sharing is more fulfilling than owning. Because corporations would rather the landfills overflow than anyone get anything for free. Because scarcity is a myth constructed to keep us at the mercy of the economy. Because a sunny day outside is better than anything money could buy."

-with the motto that we are all learners and we are all teachers, free skools offer a variety of classes for free with an emphasis on skill sharing. free skool santa cruz organizes quarterly classes in homes and public spaces on local plant identification, meditation, canning, bike repair, conversational spanish, internet security and more.

-online, websites such as freecycle and craigslist provide forums for locating, and offering, free goods and services. wikis and software exchanges provide free information and resources. it has even been argued that the internet itself operates as a (threatened) gift economy.

-in your neighborhood free boxes, book exchanges, and babysitting coops can all function as gift economies.

what can you offer? what do you truly need?

on water.

i grew up in southern california during a drought. "if it's yellow let it mellow" was the key phrase and my 3rd grade teacher taught us songs about being "drop-busting" superheros. but as soon as the rains came the push for conservation ended. despite the variable levels of local water tables, we are currently in the midst of a worldwide water crisis. (a crises that has become even more critical due to corporate water privatization.) by becoming more water-efficient in our daily lives we can prevent the construction of new dams, desalinization plants, and other environmentally destructive projects. here are a few water saving ideas.

-toilets compose 40% of residential water use. using water displacement devices in your toilet can save up to a gallon a flush. put bricks or similarly large and dense objects in your tank. (jugs filled with beans, sand or pebbles also work.) and maybe don't flush so often.

-prevent leaks. a helpful guide for detecting and stopping leaks can be found here.

-use greywater for plants. the
greywater guerrillas explain how to use waste water from sinks and showers for garden irrigation.

-
wash dishes by hand instead of using a dishwasher (the average dishwasher consumes 15 gallons of water per load.) to conserve water soap up all dishes first with a wet sponge and then rinse.

-
doing laundry by hand also saves on both water and energy (the average washing machine uses 55 gallons of water per load.) if you are using a machine, using the cold setting and drying clothes on the line can still save energy.

-if you live where water is potable, don't buy bottled water. despite public misconception, tap water in the US is generally healthier for you because its contents are regulated and monitored. if you think your water might be sketchy, contact your local water board. they are required to test your tap and confirm its safety.


i know that some of these ideas require time and labor. they also connects us to our own cycles of use and maintenance. and the time spent washing dishes or wringing clothes can provide a space for thought and simplicity within this highly mechanized society.

living local.

food is a highly political matter. and it is an issue that we are all intimately involved with. as organic food becomes more profitable, the industry's practices are beginning to mirror big agribusiness (factory farming, long distance travel, corporate ownership.) "organic" is no longer a mark of sustainability but eating food that is harvested locally supports small farms and businesses, saves energy, and connects you to a local land base (even mainstream media outlets like Time Magazine and NPR have begun to cover the benefits of eating local.) maintaining your own garden, picking up a weekly box of goods from an area farm in the form of a CSA, or buying produce at farmer's markets, you can build your own relationships to food, to seasons, and to location.

and the politics of location are central to this discussion. access to any produce, let alone local produce, is nearly impossible in some urban neighborhoods.
it is also common knowledge that a bag of highly processed and packaged potato chips is cheaper to buy than some fresh potatoes. (the reason for this, as Michael Pollen explains in his excellent NY Times essay You Are What You Grow is farm subsidies. a policy that is rarely debated but has global impacts on labor, the environment and health.) in response to these inequities of social location food justice activists are fighting to bring healthy and affordable food options to their communities through community gardens, CSAs and co-ops.

connection to a local food shed is not mere "consumer activism." it is a matter of security, health and advocacy.

plastic-free.

damn. plastic is nasty stuff. off-gassing, "leeching," petroleum based and wasteful. it may be ubiquitous but it's generally unnecessary. here are some less toxic alternatives. they may take more time, or a bit of cash at first, but they are definitely worth it.

-carry your own reusable water bottle. klean kanteens are a lightweight option.

-buy as much as you can from bulk bins. bring your own cotton bags (such as eco bags) for grains and beans. bring glass jars for honey, oil and shampoo bought by the ounce.

- use reusable bags for the vegetables you buy at the store or at a farmer's market. if you dampen
eco bags before putting greens in, they'll stay fresh longer.

-use old glass jars for storing dry bulk foods, leftovers, water, ice tea, etc. consider microwavable glass containers for tupperware.

-as an alternative to ziploc bags, use wax paper bags. these can be found in most natural food stores.


-make your own bread and tortillas. or if you buy them fresh and local they often come in paper wrappers.

-consider making your own hummus, salsa, etc. over buying it prepared in plastic containers.

-composting and recycling automatically reduces the amount you'll have to throw out, reducing the number of trash bags you'll use. compostable bags are ridiculously expensive but then you shouldn't have to buy them very often.
