Bamboo Bamboozle
December 2014

‘Green’ Clothing Made with Toxic Chemicals

bambooBamboo is rapidly renewable and requires few pesticides to grow. However, bamboo fabric manufacturing is a chemically intensive process that doesn’t provide clear and legitimate product labeling. Misleadingly using the terms eco-friendly and green becomes greenwashing when applied to items such as bamboo clothing.

As the Fair Trade Commission describes the overall process, “Most bamboo textile products, if not all, are actually rayon, which typically is made using environmentally toxic chemicals. While different plants, including bamboo, can be used as a source material to create rayon, there’s no trace of the original plant in the finished rayon product.”

This example points out the public vigilance required to secure more sustainable, environmentally friendly products. Third-party verification of all claims is recommended. Products made of the bamboo stalk itself, such as poles for furniture or planks for flooring, remain true to their naturally sustainable source.

Cell Phones and Router Microwaves Stress Plants
December 2014

Radiation Effects on Greenery

cell-phoneEvidence of the effects of wireless technologies on human health continues to be controversial, with agreement on results remaining elusive. Now a new study published in the Journal of Plant Physiologyfound that human-generated microwave pollution can potentially be stressful to plants.

Researchers from Romania’s Estonian University of Life Sciences tested three common garden plants—parsley, celery and dill weed. They exposed each to the types of microwave radiation equivalent to those produced by cell phones and wireless routers. Then these radiation-exposed plants were compared with identical plants not exposed to the radiation.

The scientists noted that the irradiated plants had thinner cell walls; smaller chloroplasts (cellular sites of photosynthesis); smaller cell mitochondria (centers of energy production); and greater emission of volatile compounds, particularly monoterpenes and green leaf volatiles, which are protective, life-promoting components of the plants’ essential oils.

The effects were stronger for the type of radiation produced by wireless routers. While essential oil production overall was increased by the frequency of the microwaves produced by cell phones, it was decreased by the frequency emitted by the routers.

 
Make Mulch

Enrich Garden Soil Naturally

mulchHomeowners with gardens have many natural, organic and sustainable options for mulching, which enriches soils with nutrients, helps retain moisture and controls weeds. In most regions, many types of trees can provide ingredients. In northern areas, ridding the yard of fall leaves yields a natural mulch.

Apply ground-up leaves, especially from mineral-rich oak and hickory trees, so they biodegrade by growing season. OrganicLandCare.net suggests choosing from double-ground and composted brush and yard trimmings; hemlock, pine, fir and Canadian cedar; and ground recycled wood.

 
Energy Efficiency Improves Family Health
October 2014

Good for the Environment and Personal Well-being

houseResearch from Columbia, Maryland’s National Center for Healthy Housing suggests that adding insulation and more efficient heating systems can significantly increase the health of household residents. The researchers studied 248 households in New York City, Boston and Chicago that underwent energy conservation improvements by trained energy efficiency professionals, including installing insulation and heating equipment and improving ventilation. After the improvements, subjects reported reductions in sinusitis (5 percent), hypertension (14 percent) and obesity (11 percent).

Although a 20 percent reduction in asthma medication use was reported, two measures of asthma severity worsened; the scientists called for further study of the asthma-related outcomes.

A similar study from New Zealand’s University of Otago examined 409 households that installed energy-efficient heating systems. Children in these homes experienced fewer illnesses, better sleep, better allergy and wheezing symptoms and fewer overall sick days. In examining 1,350 older homes where insulation was installed, the research also found improvements in health among family residents.
