There’s a lot “bad” about conventionally grown cotton—cotton grown with the aid of synthetic chemicals, that is. The Organic Trade Association (OTA), a nonprofit trade group representing America’s burgeoning organic cotton industry, considers cotton “the world’s dirtiest crop” due to its heavy use of insecticides. The nonprofit Environmental Justice Foundation (EJF) reports that cotton uses 2.5 percent of the world’s cultivated land yet uses 16 percent of the world’s insecticides—more than any other single major crop.
Three of the most acutely hazardous insecticides, as determined by the World Health Organization, are well represented among the top 10 most commonly used in producing cotton. One of them, Aldicarb, “can kill a man with just one drop absorbed through the skin,” says OTA, “yet it is still used in 25 countries and the U.S., where 16 states have reported it in their groundwater.”
Conventionally grown cotton also uses large amounts of nitrogen-based synthetic fertilizer—almost a third of a pound, says the OTA, to grow one pound of raw cotton. To put that in perspective, it takes just under one pound of raw cotton to make one t-shirt. Researchers have found that the fertilizers used on cotton are the most detrimental to the environment, running off into freshwater habitats and groundwater and causing oxygen-free dead zones in water bodies. The nitrogen oxides formed during the production and use of these fertilizers are also a major part of the agricultural sector’s greenhouse gas emissions.
This is all true despite that the use of sprayed insecticides is quickly decreasing with the advent of genetically engineered cotton seeds that have insecticides bred right into them. A third of global cotton cropland and 45 percent of world cotton production now uses genetically engineered seeds. This poses a whole other set of issues, as some scientists fear that the proliferation of such “Frankenseeds” can lead to pest immunities and even the unleashing of so-called “super pests” that can resist virtually any pesticide.
Organic cotton farming eschews synthetic chemicals (as well as genetically engineered seed) in favor of time-tested natural alternatives that ward off pests, replenish and maintain soil fertility and generally optimize growing conditions without compromising the environment or our health. “Composted manures and cover crops replace synthetic fertilizers; innovative weeding strategies are used instead of herbicides; beneficial insects and trap crops control insect pests; and alternatives to toxic defoliants prepare plants for harvest,” says the Sustainable Cotton Project (SCP), a nonprofit that helps cotton farmers in California’s Central Valley discover the economic, environmental and health benefits of avoiding synthetic chemicals.
For consumers able to pay a little more, there are now thousands of organic cotton retailers. The OTA reports that American farmers increased plantings of organic cotton by 26 percent in 2009 over 2008, while sales of organic cotton fiber grew 10.4 percent (to $521 million) during the same time. The OTA’s Organic Pages Online lists vendors (and links to their websites) by product type; many sell online as well as through retail chains. Even some big box stores now offer organic cotton items. So keep your eyes peeled and be a part of the solution by opting for organic cotton next time you stock up your drawers.
Dear EarthTalk: What are some simple things I could do to green the office I work in?
— James Raskin, Framingham, MA
No matter how green your office may be already, there is surely room for improvement somewhere. Here are 10 suggestions to help get you and your co-workers further along on the path to office sustainability:
(1) Take your Office’s Green Footprint: The website TheGreenOffice.com, an online retailer specializing in green office products, makes available a free Office Footprint Calculator to gauge what kind of effect you and your co-workers are having on the environment and identify how to make improvements.
(2) Save Trees: The average office worker uses 10,000 sheets of copy paper a year. Refrain from printing when you can, use both sides of a sheet, and recycle so that the recycling industry will have raw material.
(3) Power Down: Artificial lighting accounts for almost half of all office electricity use. Turn off lights that are not being used. Better yet, install motion sensors that do it automatically when no one is in the room. Also, shut down computers overnight, and set them to go into sleep mode when sitting idle.
(4) Minimize E-Waste: Upgrade or repair the office computers instead of junking them. So-called “e-waste”—toxin-leaching computers and electronics—is a huge problem all over the world now.
(5) Telecommute: Encourage workers to work at home when possible to save car trips. For those who must come to the office, encourage bicycling if it is safe. Also some firms now subsidize employee public transit costs to discourage driving. And online video tools like Skype can help cut down on business trips.
(6) Green Screen Your Suppliers: Ask your vendors how they are greening their operations. Just posing the question can start them thinking, the precursor to action. Demand recycled paper and soy-based inks from your printers, and buy only green office supplies—which are now widely available.
(7) Clean Greener: Make sure your cleaning service uses non-toxic, green friendly products—if they don’t, offer to supply them—so that you can breathe easy when you’re trying to get your own work done.
(8) Eco-Renovate: If you need to renovate or upgrade anything, greenest options abound, including non-toxic paints, natural fiber carpeting, energy efficient windows and Energy Star-rated office equipment.
(9) Drink Tap Water: Having big jugs of water lugged in and out every week by the bottle water company is not only unnecessary but a big waste of energy. Most tap water is safe to drink; if yours isn’t or you’re not sure, put filters on the kitchen spouts or buy filtered water pitchers and keep them in the office fridge.
(10) Put Your Heads Together: Form a committee to organize and monitor your office’s green practices, to ensure that your office’s green goals don’t fall away if one or two committed employees move on, and to reinforce the importance of doing the right thing across the organization.
