Energy Intensity
Every stage of civilization is characterized by its use of energy. From burning wood to steam engines to our electrified society, energy is behind everything we do. Over time, human society has become increasingly energy intensive. As our standards of living have improved and as we overcome the effects of weather – either cold or warm – it takes more and more energy to live the lives we lead.
Catching Kelp In Maine
Farming, forestry, mining and recreation are the primary vocations in rural America. In coastal areas like Maine, fishing joins the list. And for Maine, commercial fishing has long been a major engine for the economy.
Solar Power 24/7
The biggest challenge facing both solar and wind power sources is that they don’t produce power around the clock; they only work when the sun is shining or the wind is blowing. As a result, they don’t quite measure up to the requirement for power on demand.
Breeding Dory
The regal blue tang is one of the most common and most popular marine aquarium fish in the world. In the U.S., they have been ranked as high as the 10th most imported fish species out of over 2,000 that enter the country. Apart from aquarium hobbyists, millions of people now associate blue tangs with the character Dory in a couple of popular animated films.
A Solar Airport
Cochin International Airport in southern India is the seventh busiest airport in the country. Its managers were fed up with the facility’s large electric bills and decided to take matters in their own hands.
Prowling Cougars
What large mammal routinely kills 200 humans in the Eastern United States every year? Here’s a hint: It’s not cougars. It’s actually overabundant white-tailed deer.
Hydrogen From The Ocean
Hydrogen is the most abundant element in the universe. Estimates are that it comprises 75% of all matter. There is plenty of it here on earth too, but almost none of it is in its elemental form. It is mostly bound up in compounds like water.
Ebola And Bats
Filoviruses have devastating effects on people and primates, as evidenced by the 2014 Ebola outbreak in West Africa. For nearly 40 years, preventing spillovers has been hampered by an inability to pinpoint which wildlife species harbor and spread the viruses.
Grass-Powered Cars
Several major automakers are betting on hydrogen-powered cars as the future of personal transportation. The first of these cars are already available in California. What isn’t readily available is the hydrogen to power them. There are very few hydrogen stations out there and hydrogen is pretty expensive.
Sharks In Hot Water
The majestic great white shark has been around for a very long time. Its evolutionary origin dates back 14 to 16 million years. And while great whites still enjoy decent populations off the coasts of Canada, Australia, and the United States, the same can’t be said for South Africa’s great whites.
Restoring An Urban River
Those of us who grew up in Los Angeles are quite familiar with the L.A. River. It’s not much of a river at all. Just a 51-mile-long concrete drainage ditch that shows up from time to time in movies like The Italian Job and Terminator 2.
A Refuge For Black Spruce
In the Canadian province of Quebec, a study of more than 26,000 trees across an area the size of Spain forecasts winners and losers in a changing climate.
Floating Solar
Installing solar arrays on the surface of bodies of water is an idea that is catching on around the world. Such installations are especially attractive in places like Japan, where land resources are scarce. In the UK, there are a couple of these so-called “floatovoltaic” projects underway – one outside of London and one near Manchester.
Packaging From The Sea
Waste due to excess packaging of the products we buy is a real problem. It is one that most of us are conscious of and more and more businesses are making efforts toward eco-friendly packaging. There is increased use of cardboard, which is recyclable. Most of us try to reduce our waste through recycling. But as we buy more things online and have a growing variety of things delivered to our homes, it is a struggle to receive the things we order in good condition and not end up with piles of packaging materials.
Amazon In Peril
A constitutional amendment being discussed in the Brazilian Senate threatens to set back decades of conservation efforts in the Amazon.
Light Pollution And Early Spring
We have talked about the impact of light pollution on our ability to see stars and the Milky Way. We have also discussed its impact on our circadian rhythms. Recently, scientists in Great Britain published a report on the relationship between light pollution and the timing of when trees produce their buds. The results of the study suggest that light pollution is causing plants to jump the gun on spring.
