Dried arrangements and holiday wreaths may contain invasive plant species, such as Oriental bittersweet (found throughout the Eastern and Great Lakes states) and multiflora rose (found through the Eastern and Midwest U.S., Colorado, California and Oregon). When these arrangements hang outside, wind and birds foraging for food can carry away berries and seeds, which may [...]

A sure-fire sign of the holiday season is brilliant neighborhood light displays. Festive colored lights boost holiday spirit – and they boost energy bills, too. Americans use up to 40 percent more energy during the holiday season and much of that energy is attributed to decorative lights. Luckily, you don’t have to lose the lights [...]

Watersheds are areas of land in which all water drains into a common body of water. Because water does not obey political boundaries, watershed maps can cross county, state and even national lines. The size of a watershed can vary, but all bodies of water have one. You can think of watersheds like pieces of [...]

Along with heavy rains and high winds, the impacts of landfalling hurricanes and tropical storms also include more tornado formation. The larger the tropical cyclone and the longer it spends over land, the greater the probability that tornadoes will form as the system moves. Since 1995 in the Gulf of Mexico, hurricane strength has increased [...]

Fewer daylight hours often means that we spend more time inside during fall and winter.  While heating and cooling account for more energy use than other household activities, small appliances and lights still add to home energy costs. Last year, Louisiana residents spent 266 dollars on energy for home lighting. Viewer Tip: The Alliance to [...]

Fall is here and wild animals are prepping for the winter. Some species migrate to warmer places, and not just birds. Monarch butterflies, dragonflies and even some mammals migrate south in the fall. Other species grow thick winter coats to stay warm. In the case of the arctic fox, snowshoe hare and short-tailed weasel, those [...]

October is Children’s Health Month. According to the Environmental Protection Agency (EPA), when food, water or air is polluted, children are more affected by that pollution than adults. Children eat, drink and breathe more per pound than adults. Also, their bodies are still developing and their behavior can expose them more to chemicals and organisms. [...]

The change of seasons is an important influence on animal behavior. Whether it’s the hot season turning cold or the dry season turning wet, wildlife has to adapt to survive. One strategy is migration. Songbirds, waterfowl, raptors and hummingbirds travel north and south each year, some as far as the tropics! Caribou and pronghorn shift [...]

If the water we use is replenished by precipitation, why do we need to save it? The short answer is that while water can be purified and reused over and over thanks to the natural water cycle and wastewater treatment technology, it may not be available everywhere—or every time—it’s needed. When we all use water [...]

Did you know that at least 30 percent of the water you use at home is outdoors? In drier parts of the country, homeowners use as much as 70 percent of their water outdoors. Viewer Tip: This autumn, look for ways to be more water-efficient and fall into good water habits. Adjust your watering schedule [...]

According to EPA’s AIRNow Program, the summer of 2009 had better ozone air quality than years past. Many U.S. cities experienced at least 80 percent fewer days when ozone air pollution reached levels that were Unhealthy for Sensitive Groups (USG) or higher on the Air Quality Index. This trend was especially apparent in the Midwest, [...]

Marine debris, or trash that ends up in oceans and waterways, is harmful for wildlife, humans and ecosystems. Curious animals such as seals, dolphins and otters accidentally ingest or become entangled in these items. Other animals, such as birds and turtles, mistake trash for food. Ingested trash can choke and poison them, as well as [...]

September is National Preparedness Month! A 2009 national survey by the Federal Emergency Management Agency (FEMA) found that just over half of respondents have set aside emergency supplies at home, but less than half of survey respondents have a household emergency plan. Viewer Tip: Are you prepared? Make sure you have the supplies and information [...]

On warm days, outdoor air pollution concentrations often rise to levels that can impact our health. But did you know that air pollution inside can be worse than air pollution outside? The air we breathe inside a sealed building can be 25 to 100 percent more polluted than the air outside. The U.S. Environmental Protection [...]

The Centers for Disease Control estimate that more than half of all flood-related drownings occur when a vehicle is driven into flood waters; the next highest percentage of deaths is from walking into or near flood waters.  Many people falsely believe that cars, trucks and SUVs are heavy enough to maintain contact with the road [...]

While global sea-level is rising at a rate of about 1.2 inches per decade due to an influx of glacial melt water and thermal expansion of the oceans, the relative sea-level rise or fall that each coastal location experiences is dependent on several factors. Local sea-level can rise faster than the global average due to [...]

A new study from the U.S. Geological Survey shows that scientists found mercury contamination in every fish sampled in 291 streams around the country.  One-quarter of fish sampled exceeded mercury levels set to protect humans who eat average amounts of fish; two-thirds exceeded mercury levels of concern set by U.S. EPA for fish-eating mammals. The [...]

Those who are involved in outdoor sports and recreational activities between the months of May and September can be exposed to the dangers of lightning.  The majority of injuries related to lightning occur over the summer, with 80 percent of injuries occurring between 10 am and 7 pm.  Viewer Tip:  If you spend time outdoors, have [...]

Did you know that most humans would operate on a 25-hour cycle without exposure to sunlight? Instead, we operate on a 24-hour cycle, following the 24-hour cycle of the sun.  Humans are “diurnal” animals, sleeping during the night and being active during the day, as opposed to “nocturnal” animals which are active at night.  When [...]

The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) organizes volunteers in communities throughout the United States to collect and measure precipitation — rain, hail and snow — in their communities. Citizen volunteers are trained how to measure precipitation using a rain gauge and hail pad, record their data and report their measurements online. Data [...]
