Earth Calendar for July 30th and July 31st

With dry conditions and drought conditions covering 80 percent of the contiguous United States, now is a great time to analyze water use on your property. Every day in the U.S., more than 7 billion gallons of drinking water is used to irrigate landscapes, at least half of which may be wasted.   We can reduce water waste with an in-ground hose system that reaches plant roots and prevents evaporation. You can buy soaker hoses and weave them in and out of your plant beds several inches below the surface. Drip irrigation has solid hoses you add holes to, permitting more precise control.

On Monday, July 30th the Honorable Kuninori Matsuda, Consul General of Japan, will join federal, state, county and local officials to launch the “Operation 1000 Cherry Tree Project” in Dayton Ohio. The project was developed by Alex Hara, a Japanese-born businessman living in Dayton. Hara was inspired to initiate the project after seeing the devastation to his homeland, Japan, following the 9.0 magnitude earthquake and ensuing tsunami that claimed almost 16,000 lives and left over 3,000 missing in March of 2011.

Earth Calendar for July 23rd and July 24th

The sun emits radiation in the form of ultraviolet (UV) radiation. UV radiation is at its highest when and where the sun’s rays are the strongest. This means that UV levels will be highest around noon on a clear sunny day, as well as during the summer months. UV levels will also be highest near surfaces that reflect sunlight, such as water, snow and sand. Exposure to UV can cause sunburn, skin aging, skin cancer and eye damage.  Between 2002 and 2006, the rate of melanoma skin cancer diagnoses in Kentucky was 14 percent higher than the national average.

According to Cincinnati’s Metropolitan Sewer District, every year, about 14 billion gallons of raw sewage mixed with storm water overflows from our sewers, contaminating local streams and rivers and flooding basements. When water becomes too foul, fish die, wildlife habitats are destroyed, and our drinking water is compromised. Large volumes of contaminated runoff and wastes that enter the storm system are a considerable part of this problem.This can be helped! Just labeling the storm drains in your neighborhood as “no dumping” zones can reduce the occurrences of pollution.

One way to cut down on paper and energy use is by opting out of home or business phone book delivery, and do all searching online.  According to a recent Harris Survey, the majority of American adults have already stopped using paper phone books and don’t want them.  Unfortunately, it’s also true that most don’t recycle the phone books they receive and about 70% of states still require them to be published.  To request that your name be removed from phone book distribution lists, register at the

In an average year, Americans cut enough grass and other clippings from their yards to equal the weight of 91 Empire State Buildings.  All that waste has to go somewhere and more than 40 percent ends up in landfills.  Some waste makes its way into our waterways where its nutrients become food for algae blooms that close beaches and recreation areas, produce toxins and create “dead zones”.

The Environmental Protection Agency and the Department of Transportation will soon put the final stamp of approval on a plan to require better gas mileage for new vehicles. A new campaign is under way to show support for the new mileage standard – 54.5 miles per gallon by 2025.  The benefits include saving money at the pump, creating jobs in the auto industry, reducing our dangerous dependence on oil, cutting harmful carbon pollution and educating the public about what it all means.

Summertime means that weather conditions are favorable for ground-level ozone formation. Emissions from motor vehicles are the primary source of ozone-causing pollutants, accounting for almost half of our air pollution.  Because heat and sunlight are important factors in ozone formation, ozone pollution generally peaks during the months of April through October, on hot, sunny days with little or no wind and no precipitation.   On these days, it's particularly important to reduce how much you drive. Travel to work by taking public transportation, share a ride, walk or bike.

Dry cleaners across the country are working to recycle 25 million hangers, enough steel to equal six Statues of Liberty.   In addition to her 125 tons of steel, Lady Liberty also contains 31 tons of copper and her base is made of 27,000 tons of concrete. The program was launched in January with the intention of keeping 10 million hangers out of landfills this year. Cleaners volunteered to take in used hangers from customers, reusing those that could be and sending others to a metal recycler. By April, the 10 million goal had been reached. By mid-June the total was up to 13.6 million.
