Hands Across the Sand, a statewide, peaceful protest against offshore drilling, was held throughout Florida's beaches on February 13th. Despite the colder-than-average weather, large groups of citizens made their way out to the beaches to make their voices heard and to show their support for Florida's beautiful landscape, with the hope that it will stay beautiful.

Traditionally, auto detailing has employed a range of not-so-green-friendly products such as ammonia, volatile organic compounds (VOCs), nonphenolethoxolates (NPEs), abrasive detergents, and chemical-based leather, vinyl, fabric and carpet treatments. Inside the car, they can off-gas harsh airborne pollutants; when washed down storm drains they can wreak havoc on public water supplies.

Among the most intelligent animals on Earth, three species of hyenas still roam in wilder parts of Africa and Asia. In general, hyenas are large, strong, flesh-eating animals that hunt a wide range of prey but mostly feed on carrion (the kills of other predators). They most closely resemble dogs but are in fact more closely related to cats. When full-grown, hyenas range from about 3 1/2 to 5 1/2 feet long and weigh between 75 and 175 pounds. Considered as smart as some primates, hyenas work in teams to hunt zebras and wildebeests. They communicate through a series of yells and growls, and their cries resemble human laughter.
