Wheying the Positives and Negatives of Greek Yogurt

Being that it is a requirement of living, it is likely that you have seen a grocery store in your lifetime. (If not, congrats to you for this incredible feat in modern society).  Among the common items of bread, eggs, and cheese that you would normally find in the grocery store is the now ubiquitous Greek Yogurt section. Popular for being rich in protein, and its smooth texture, Greek yogurt has taken off as an industry within the past five years. In fact, “…Yogurt production in New York…has tripled between 2007 and 2013.”[1] What yogurt companies and John Stamos have not told you however are the consequences the production of their products have had on the environment.

Unlike traditional yogurt, the Greek variety, “…Yields huge quantities of acid whey, a byproduct that kills aquatic life during decomposition.” In the production cycle, acid whey (which is common component in the making of inexpensive butters and creams) is one of the byproducts that separates from milk after it has been curdled.[2] Yet, because of the aforementioned boom in production, yogurt companies are left with a tremendous amount of waste that cumulatively can greatly impact our oceans, rivers, and streams. Acid whey naturally takes away oxygen from water which has the effect of progressively killing any aquatic life in the area. For example, after an Ohio cheese factory accidentally spilled acid whey into nearby Sandy Creek, close to 5,400 fish were killing along the 1.5 mile river.[3] These figures are pretty extraordinary, but can only provide a glimpse into the potential environmental ramifications if a larger scaled spill were to happen.

Currently, for every three or four ounces of milk, Chobani and other companies can produce only one ounce of creamy Greek yogurt. The rest becomes acid whey.”[4] So what can we do to reverse this trend? According to The Verge and The Modern Farmer several sustainable options are currently being explored. The most promising idea in use is located at a farm in Scipio Center, N.Y where they have successfully turned acid whey into methane, which then is converted into usable electricity. In a simplified and less disgusting version of the process, acid whey and manure are combined in tanks with heat for approximately 20 days. Here the cultures in acid whey break down the contents of the mixture which, in this case, releases methane embedded within the manure where the gas is used as a raw material for electrical generators which power the farm.

Yet, the anaerobic digesters which are required tools for the New York farm require millions in capital investment and are not likely to be available to the local farmer. As a result, we need to cultivate more practical ideas to meet this growing challenge which faces our environment and aquatic life. Here at LGBG we want to empower you with this information to go out and make a difference. Together lets collaborate and inspire to create a solution so that we can all live green, and be green.

Unexpected Effects of Extreme Hot Weather

by

The National Oceanographic Atmospheric Administration confirmed that the record-breaking warmth in July was part of the warmest 12-month period experienced by the lower 48 states since the 19th century. In fact, this past July was the hottest month on record for the continental states since such record keeping started in 1895. Additionally, the drought conditions caused by the heat has expanded to cover 63% of the continental United States (http://weather.aol.com/2012/08/08/july-2012-is-hottest-month-on-record-in-u-s/#page=1).

Now we are witnessing some unexpected effects of this year’s hot weather. First of note is a major bear problem across the country. As a consequence of lack of availability of their normal diets of greens and berries because of failed production, bears are out in record numbers seeking food by rummaging through garbage, ripping through screens on houses and even crawling into cars in search of food. Problems with bears invading human space have been noted all over the country. Fortunately, no injuries to humans have been cited. The bear problem also could further hurt farmers, who already have been negatively impacted by the harsh drought conditions, especially corn farmers. As the hot weather has negatively affected the availability of acorns and beechnuts, on which bears typically rely, these animals now are forced to fatten up on corn. In some states, such as Vermont, the Department of Fish and Wildlife has recommended that farmers bring in their corn crops as soon as possible.

A second adverse effect of harsh summer weather is poor air quality and its resultant increases in heat-related illnesses. Heat waves lead to heat strokes and dehydration, representing the most common cause of weather-related deaths. Warmer temperatures in urban centers place an increase demand for electricity, which in turn results in increased air pollution and greenhouse emissions from power plants. Extreme heat conditions trigger severe storms that threaten human life and health in numerous ways, including, but not limited to:
• Reduction of available fresh food and water;
• Interruption of communication, utility and healthcare services;
• Contribution of carbon monoxide poisoning from the use of portable generators during storms;
• Increases stomach and intestinal illnesses among evacuees;
• Contribution to mental health problems, such as depression and posttraumatic stress disorder.

Thirdly, the economic impact of harsh summer weather causes overwhelming energy demands resulting in brownouts and blackouts that threaten business operations and daily lives of citizens. Sea level rise and frequent intense storms disrupt energy production and delivery. Extreme heat negatively affects travel and tourism with the loss income completely destroying seasonal businesses that totally rely on the summer months for their survival.

While these excruciating hot summers may represent an inconvenience to some people, the reality is that severe heat and drought conditions threaten our very existence. As scientists work to find solutions to these problems, we all need to be mindful of the steps we can take to reduce our environmental footprints. In other words, let’s strive to be part of the solution and not part of the problem. Let’s live green, be green.

Farmers face huge loss in corn production as a result of drought conditions.

Green Office Furniture: Could the Idea Catch On?

by

I recently came across an innovative work desk setup that helps to harness its own energy, effectually producing and using its own recycled energy in a self-sustaining cycle.  (Although the setup does not yet produce enough energy to completely power its many electronic vices, the idea is that it will one day be completely self-sustainable, and therefore, completely unplugged from any power source other than itself.)  The desk design, appropriately called “Unplugged,” was designed by Eddi Törnberg, and is meant to generate all the energy it needs from everyday office activities of the person sitting behind it.

The desk setup has outstanding features, such as the ability to harness power from the heat energy transferred from the user’s computer to the desk top, and even from the user’s back to the back of his or her chair.  The floor mat or rug that is also part of the design has been constructed with technology that allows it to harness energy from the pressures applied to its surface, from walking over it or sitting upon it.

While the idea is still far from mass development or even complete sustainability as an independent workspace, it carries with it a tremendous amount of integrity as an engineering feat.  I recommend you look a bit further into this truly intriguing design.  It may very well be the precedent necessary to slowly reconstruct the future as we come to imagine and realize it.  These green, eco-friendly designs can come to change the world someday, and it could happen in fewer more beneficial areas than within the workplace.
