This was the third test flight since the project began last summer, aimed at reducing the impact on the Puget Sound area.
- Ozone Could Recover -
A report from U.N. scientists states the ozone layer could recover to pre-1980s levels by 2045-60, though it will take longer for the hole over Antarctica (2073). Treehugger reports the ozone layer recovery is partly due to the Montreal Protocol, signed in 1987, which phased out CFCs and other ozone depleting chemicals.
- Greener Retail Stores -
Well-known retailers, including L.L. Bean, Office Depot and Kohl's, are joining the movement for greener stores. Kohl's details their new store prototypes on their "Green Scene" site, noting efficient water usage, improved air quality and regionally sourced materials. L.L. Bean currently has nine LEED certified retail stores, including one award for Gold.
- eWaste Litters India -
What happens to cell phones, computers and other electronics when we are done with them? They can end up piling up in other countries like India, where e-waste adds up to approximately 1,000 tons per day. This amount could increase by 500 percent by 2020. Some e-waste enters Asian countries illegally, according to Tiny Green Bubble, and is salvaged for parts. In addition to the problem with mass amounts of waste, children living in these countries are also being exposed to dangerous chemicals.
- New Coral Reefs Found -
New coral reefs were found in the Mediterranean off the coast of Tel Aviv, Israel in an area known for sparse sea life. An exploration team from the University of Haifa’s School of Marine Sciences piloting the exploration vessel Nautilus made the discovery. The reefs are located seven hundred meters under sea and may help scientists learn more about their environment and survival.
- Walmart Produce Plans -
Walmart announced a new plan for sustainable agriculture that will help farmers with smaller operations expand their businesses and increase consumer’s access to fresh food. The plan has three major goals: to support farmers and their communities; produce food by reducing environmental impacts and waste; and sustainably source agriculture products, focusing on palm oil and beef production. In the United States, the Heritage Agriculture program will source produce from identified states and regions where agriculture is most successful. More information on the plan is available on Walmart’s corporate website.
- Coffee Cup Recycling -
Starbucks is currently using New York City as a test site for the recycling probability of its coffee cups. The company, which started the test in mid-September and will conclude it in November, is collecting cups at its NYC locations, which will then be sent off to a recycling facility. Currently, Starbucks is only looking at the cups, not the lids or sleeves, but is aiming to provide reusable or recyclable cups by 2015. The company currently uses 3 approximately billion coffee cups per year which pile up in landfills.
- Temperatures on the Rise -
The past decade was the warmest according to scientists, blaming global warming and greenhouse gases in the atmosphere. This data was included in the annual "State of the Climate" report released by the U.S. National Oceanic and Atmospheric Administration in July. Temperatures have climbed steadily, with the 1980s considered the warmest decade until each year in the 90s and 2000s exceeded those numbers.
- Dead Zones Increase -
Ocean dead zones are increasing at a dramatic rate, according to a report from the U.S. government released in September. An ocean dead zone is where hypoxia or low levels of oxygen are found. Marine life have a harder time surviving in these areas and abandon them in search of more oxygen. According to reports, the number of dead zones has increased from 12 in the 1960s to over 300 today. Hypoxia can be caused by several factors, including an increase in phytoplankton, agricultural runoff and overfishing.
- Efficient Appliances -
The Department of Energy is proposing a new rule that will make refrigerator and freezers 25% more efficient in 2014. This change could amount for $1.4 million in economy savings and reduce pollution from power plants while also saving consumers money on their electric bills. While the refrigerator uses more energy than most appliances, future upgrades are planned for air conditioners, furnaces, washers, dryers and dishwashers.

- Buy Food in Bulk -
Buying food in bulk has both economic and environmental benefits, reports Earth911. Bulk purchases reduce the amount of packaging, cut down on the number of trips to the grocery store, encourage healthier eating at home and lessen the amount of garbage and materials that need to be recycled. While not all foods have a decent shelf life, many items like nuts, pasta, rice and cereal will keep for long periods of time. These items also come in handy for trail mix, soups, salads and other homemade recipes.
