Exotic animals are a growing problem in Florida. From Burmese pythons to Nile monitors, these animals are invading Florida and destroying the ecosystem. A fast, accurate way to identify the many exotic animals is needed by professionals and volunteers in the field. With over 6.4 million iPhones active in the United States alone, what better solution than an iPhone app?

My name is Luana Xiong. I am 14 years old and part of Merced County 4-H in California. I have been in 4-H for five years. Some of the projects I do in 4-H include photography and arts and crafts, but the one part of 4-H that I absolutely love is science.

For urban dwellers, trees soften a city’s hard edges and surfaces, shade homes and streets, enhance neighborhood beauty, filter the air, mitigate storm runoff, and absorb carbon dioxide. Trees may even reduce crime and improve human health. However, these benefits have not been well quantified, making it difficult for urban planners and property owners to weigh their costs and benefits or assess tree cover against competing land uses.

The United States Department of Agriculture (USDA) partnered with the Office of Personnel Management to participate in the Feds, Farmers, and Friends Feed Families (F5), a food drive.  This food drive benefited local food banks identified by state and area/local USDA offices.

I just participated in a wonderful school nutrition conference in Athens, GA that ran from September 28-30.  It was Georgia’s annual School Nutrition Directors’ Conference, and I found it to be very well organized and packed with important information.

From the waters that run deep through the earth to the moisture that composes clouds in the sky, water hydrates all life forms on earth. Water also affects global weather that makes earth hospitable for living creatures and plants. This resource is all around us yet we rarely understand the need to conserve and protect our water.

The potato is the world’s fourth largest food crop and is the largest vegetable crop in the United States. The crop originated in the Andes Mountains in South America, and in the ensuing 7,000 years, has spread across the globe. Potatoes have played an important role in saving populations of people around the world from starvation. However, the potato has had a tumultuous history, suffering from late blight disease, which caused the Irish potato famine and a severe outbreak in 2009 in the United States.

A nice break in the recent rainy weather in the eastern panhandle of West Virginia offered perfect timing for a Self-Help Build day.  The event which was held September 29, 2010, has become an annual occurrence during which volunteers gather to help families build their homes.

Renowned wildlife artists Robert Bateman and Wyland, in partnership with the U.S. Forest Service, invite American youth to “get to know” their wild neighbors of other species. The Get to Know contest encourages young people to develop a deeper appreciation of biodiversity through art, writing, photography and video. Entries based on a first-hand experience with nature can be submitted at www.gettoknow.ca from October 1 to November 30, 2010.

Farming for the Eldridge family began in the late 1800’s when Hoover Eldridge’s grandfather settled in the eastern portion of Stewart County, Tenn. Through the years the farming operation has consisted of producing crops such as corn, soybeans and tobacco, as well as a variety of livestock such as goats, chickens, pigs and beef cattle.
