Why Certification is Critical for the Industrialization of Bamboo
January 19, 2015 12:35 PM - Contributing editor
We’ve been down this path before; a new species, a new crop, a new product. A silver bullet plant that can be grown on degraded land and provide exactly what industry needs. And yet typically such plants go one of two ways; the way of Jatropha, which after a few years of being touted as the miracle plant of the biofuel industry, simply faded into nothingness; or the way of oil palm, where industrialization boomed, and with it came a mile wide trench of environmental devastation.
No plant is inherently green. And bamboo is no different. It can be grown well, and sustainably. Or it can be the cause of deforestation, conversion of natural ecosystems, and subsequent environmental and social degradation.
So why is bamboo forging a path that is likely to be different? Simply, the foremost player currently responsible for the plant’s industrialization at a global and commercial scale is setting a benchmark of sustainability in front as they pioneer and grow the plant at scale, rather than in their wake as an after thought.
Salting Roads takes a Toll on the Environment
January 14, 2015 10:49 AM - Kevin Mathews, Care2
The United States has a salt problem, and it extends well beyond the excessive sodium we consume in our diets. In the winter months, municipalities rely on dumping salt on the roads to minimize the effects of ice. Altogether, the U.S. uses ten times the amount of salt on roadways than it does in the processed foods we consume. While the salt may help to keep drivers safe, it does come at a cost:
1. It Increases Our Own Salt Consumption
You can throw salt down on roads, but you can’t force it to stay there. In due time, salt makes its ways into nearby waterways where it lingers. As a result, a lot of the water we wind up drinking has higher levels of salt than it would otherwise. Vox cites a study that finds 84% of city-adjacent streams have higher levels of chloride thanks specifically to these road-salting techniques. Apparently, during the months following salted roads, 29% of these streams have more salt than the federal “safety limits” for drinking water allow.
Global Warming History Repeats Itself
January 5, 2015 02:21 PM - David Bond, The Ecologist
The Earth's current warming is looking similar to what took place 55 million years ago, writes David Bond. And if it works out that way, the news is good: we may avoid a mass extinction. On the other hand, the poles will melt away completely, and it will take hundreds of thousands of years for Earth to get back to 'normal'. It is often said that humans have caused the Earth to warm at an unprecedented rate. However researchers have discovered another period, some 55m years ago, when massive volcanic eruptions pumped so much carbon into the atmosphere that the planet warmed at what geologists would think of as breakneck speed. The good news is that most plants and animals survived the warm spell. The planet has experienced several mass extinctions - and this wasn't one of them. But there's a catch: even after carbon levels returned to their previous levels, the climate took 200,000 years to return to normal.
Christmas gift for Gray Wolves in three states
December 26, 2014 08:32 AM - Alicia Graef, Care2
Christmas came early this year for gray wolves thanks to an awesome ruling handed down by a federal judge that immediately reinstated federal protection for them in the Great Lakes region.
The ruling affects wolves in Michigan, Minnesota and Wisconsin, and, unless overturned, will stop these three states from holding any more hunting and trapping seasons, which is expected to protect an estimated 3,700 wolves.
Do Weddell Seals have an Internal GPS?
December 23, 2014 01:15 PM - National Science Foundation
Weddell seals have biological adaptations that allow them to dive deep--as much as of hundreds of meters--while hunting, but also an uncanny ability to find the breathing holes they need on the surface of the ice. Now, researchers supported by the National Science Foundation (NSF) believe they have figured out how they do it--by using the Earth's magnetic field as a natural GPS. "This animal, we think, may be highly evolved with an ability to navigate using magnetic sense in order to find ice holes some distance apart and get back to them safely," explained Randall Davis of the Department of Marine Biology at Texas A&M University. If the hypothesis turns out to be true, it would represent the first evidence of such a trait in a marine mammal.
New study analyzes sound sensitivity of marine invertebrates
December 22, 2014 02:57 PM - Woods Hole Oceanographic Institution
Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.
Abandoned Wells Identified as Greenhouse Gas 'Super-emitters'
December 9, 2014 01:32 PM - John Sullivan, Princeton University
Princeton University researchers have uncovered a previously unknown, and possibly substantial, source of the greenhouse gas methane to the Earth's atmosphere. After testing a sample of abandoned oil and natural gas wells in northwestern Pennsylvania, the researchers found that many of the old wells leaked substantial quantities of methane.
How businesses can help preserve endangered species
December 5, 2014 08:24 AM - Sarah Clinton, Mizzou University
Raptors, or birds of prey, some of which are endangered species, typically live in environments that provide natural land cover, such as forests and grasslands. Protecting endangered raptor species helps maintain food chain balance and prevents overpopulation of common raptor prey, such as snakes and rodents. As more businesses are built on the edges of urban areas, land where raptors once lived becomes industrialized, which raises concerns about the consequences of habitat destruction on raptor populations. Now, University of Missouri researchers have found that businesses can contribute to raptor preservation efforts by engaging in less development of lawn areas and increased planting or preservation of native grasslands and woodlots.
O Christmas Tree, O Christmas Tree
December 3, 2014 10:18 AM - Allison Winter, ENN
The tradition of the Capitol Christmas Tree, or The People’s Tree, began in 1964 when Speaker of the U.S. House of Representatives John W. McCormack (D-MA) placed a live Christmas tree on the Capitol lawn. This tree lived three years before succumbing to wind and root damage. In 1970, the Capitol Architect asked the U.S. Forest Service to provide a Christmas tree. Since then, a different national forest has been chosen each year to provide The People’s Tree. This national forest also works with state forests to provide companion trees that are smaller Christmas trees for offices in Washington, D.C.
This year, the 88-foot-tall white spruce tree was harvested from the Chippewa National Forest in northeastern Minnesota by Jim Scheff who won the Logger of the Year award from the Sustainable Forestry Initiative Inc. (SFI).
That begs the question how can a logger win an award from a sustainability group?
Turkey might be a better choice than fish in the tropics!
November 27, 2014 07:12 AM - Katie Pitz in Oceanus: Woods Hole Oceanographic Institution.
On a tropical island vacation, one of the last things you want to worry about is food poisoning. Yet for many, a trip to the tropics includes a painful education in a mysterious food-borne illness called Ciguatera Fish Poisoning, or CFP.
Every year, thousands of people suffer from CFP, a poisoning syndrome caused by eating toxic reef fish. CFP symptoms are both gastrointestinal and neurological, bringing on bouts of nausea, vomiting, diarrhea, headaches, muscle aches, and in some cases, the reversal of hot and cold sensations. Some neurological symptoms can persist for days to months to years after exposure. There is no quick way to test for the toxins, and unless action is taken within hours of the poisoning, no cure once you’re sick.
