Wetlands are distinct ecosystems that are flooded or saturated by water, either permanently or seasonally.  They include mangroves, marshes, swamps, forested wetlands, bogs, wet prairies, and vernal pools.   The feature that most wetlands share is soil or substrate that is at least periodically saturated with or covered by water. Wetlands are some of the most […]

Insects can be found in every environment on Earth and play crucial roles in the planet’s ecosystems.  In fact, Biologist E. O. Wilson once said that “if all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago.  If insects were to vanish, the […]

Driving on snowy or icy roads can be pretty dangerous.  That is why roads are salted or coated with sand to provide traction in icy weather.  But excessive use of these substances is bad for the environment and sometimes a storm will blow in before the roads can be coated. In a paper published in […]

Utah’s Great Salt Lake has been plagued by excessive water use and extensive drought conditions.  As of January, the lake dropped to record-low water levels, losing 73% of its water and exposing 60% of its lakebed. According to scientists, the lake could disappear entirely within five years. Great Salt Lake is what is known as […]

When we think about wind power, we are usually talking about increasingly giant windfarms – either on land or offshore – that produce power on a utility scale.  But there is also distributed wind energy, which refers to wind technologies in locations that directly support individuals, communities, and businesses.   Distributed wind can be so-called behind-the-meter […]

The use of solar power has grown tremendously in recent years as it has declined in price and become far more competitive with other forms of electricity generation.  Its fundamental drawback, of course, is that it only works when the sun is shining.  Solar panels don’t produce any power at night.  That is, until now, […]

Not long ago, many states across the country were setting goals to obtain 20% of their electricity from renewable sources. For a few states, like New York and Washington, ample amounts of hydropower made 20% an easy target.  But for many others, 20% seemed like a very ambitious objective. Things have certainly changed.  According to […]

Photosynthesis is the process that plants use to turn water, carbon dioxide, and energy from sunlight into plant biomass.  It provides humans and much of animal life with food.  Photosynthesis is also nature’s way of reducing the amount of carbon dioxide in the atmosphere.  The CO2 is not directly stored in plants but rather is […]

Investors have poured billions of dollars into efforts to replace animal proteins with plant-based substitutes or even laboratory-grown animal cells.  Replacing meats with these products is certainly a favorable development for the climate, but it is not likely to offset livestock agriculture’s climate and land use impacts anytime soon. According to research at Stanford University, […]
