Costa Rica Opinion – I had the joy of spending Christmas in bed hoping that I would be able to re-hydrate after water was coming out of both ends of my body. There is nothing worse than the weak feeling you get after having all the water leave your body. The only other time I...
Clearing forests not only releases carbon into the atmosphere, it also triggers worldwide shifts in rainfall and temperatures that are just as potent as those caused by current carbon pollution and that pose great risk to future agricultural productivity, researchers report. Deforestation in South America, Southeast Asia, and Africa may alter growing conditions in agricultural areas as far away as the U.S. Midwest, Europe, and China, the study in Nature Climate Change finds.
It’s not a good sign when even the dogs won’t drink your tap water. “They sniff it and then drink the bottled water we pour,” said Frank Michna of Caledonia, one of hundreds of southeastern Wisconsin residents whose wells are contaminated by pollutants that may be coming from buried coal ash.

USINSK, Russia — On the bright-yellow tundra outside this oil town near the Arctic Circle, a pitch-black pool of crude stretches toward the horizon. The source: a decommissioned well whose rusty screws ooze with oil, viscous like jam.
This is the face of Russia's oil country, a sprawling, inhospitable zone that experts say represents the world's worst ecological oil catastrophe.
(Reuters Health) - Air pollution should be one of the avoidable heart risk factors - just like smoking and excess fat - that doctors warn patients to steer clear of, according to a new statement from 20 heart experts. Citing polluti...
In 2014, a 20-year-old grizzly bear named Ethyl made an epic 2,800 mile walkabout through Montana and Idaho. U.S. Fish and Wildlife Service biologists knew of her movements because of the GPS collar she wore, which sent weekly data to a satellite. Federal Grizzly Bear Recovery Coordinator Chris Servheen called her traverse into Idaho via the Bob Marshall Wilderness and Mission Mountains, which involved navigating through main streets, landfills, backyards and crossing Interstate 90, "bizarre." While male grizzlies make big movements, females rarely venture far. Yet this was but one of several similar carnivore peregrinations documented in the last fifteen years via GPS-collar technology.
Roads scare the bejeezus out of many scientists because they often open a Pandora's Box of environmental problems -- such as unleashing illegal deforestation, logging, hunting, mining, and land speculation. Far too many roads are forest...
"The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to an article in the scientific magazine Science that researchers from 26 countries have contributed to. It is an excellent example that humans and carnivores can share the same landscape, says main author Guillaume Chapron, from the Swedish University of Agricultural Sciences (SLU)
By the early 20th century, large carnivores had been exterminated from most of Europe, with just relict populations persisting. Now we have increasing or stable populations of brown bears, wolves, Eurasian lynx and wolverines, and they do not live in a remote wilderness but in a human-dominated landscape.
That is a great difference in comparison to the strategies being pursued in other parts of the world where carnivores are mainly protected in large national parks or wilderness areas, separated from people. If Europe had used that model we would hardly have any carnivores at all because there are not enough large areas of wilderness remaining."
LA VIRGEN, Costa Rica — Over just a few decades in the mid-20th century, this small country chopped down a majority of its ancient forests. But after a huge conservation push and a wave of forest regrowth, trees now blanket more than half of Costa Rica.
Far to the south, the Amazon forest was once being quickly cleared to make way for farming, but Brazil has slowed the loss so much that it has done more than any other country to limit the emissions leading to global warming.
"It’s no secret that America’s bees are in trouble: Since Colony Collapse Disorder hit the U.S. in 2006, the country’s beekeepers have reported an average annual hive loss of 30 percent. A groundswell of hobby beekeepers has emerged, wanting to do their part to save honeybees, and commercial beekeepers are racing to come up with solutions. It’s not just a critical issue for bees, but for our entire agricultural system: One-third of our food depends on bees and the industry is responsible for $15 billion in increased crop value annually.
But some progress is being made. A group of honeybee breeders across the nation are looking to hardy, resilient bees they call “survivor stock” as one important step toward a solution. A host of factors likely play a role in CCD, including habitat loss, overuse of agricultural chemicals and an array of pests and diseases. Similarly, a variety of characteristics come together under the survivor stock definition."
Brazilian president Dilma Rousseff has stirred up the wrath of environmentalists by appointing a controversial advocate of agribusiness and weaker forest conservation as her new agriculture minister.
Kátia Abreu, who has been nicknamed the “chainsaw queen” by her enemies, is included in a new cabinet that rewards political allies who supported Rousseff in her recent narrow re-election victory.
Abreu is a leading figure in the “ruralista” lobby, which prompted the government to weaken Brazil’s forest code. In congressional debates and in her feisty newspaper column, she has called for more roads through the Amazon, congressional control over demarcation of indigenous reserves, more efficient monocultures, and the approval of genetically modified “terminator seeds”.
Many people are becoming aware of ways to live that are more harmonious with the planet. It seems that we are transitioning to a very ancient understanding of how to operate here on Earth, with a very advanced ‘know how’ of technologies and methods to begin making that transition. New ways of living are coming […]
Nitrates pollution of waters is a worldwide problem and its remediation is a big challenge from the technical and the scientific point of view. One of the most used and promising cleaning techniques is the biological treatment of wastewaters operated by denitrifying bacteria. In this paper we begin a thorough study of denitrifying performances of the bacterium Azospira sp. OGA 24, recently isolated from the highly polluted Sarno river in the south of Italy. Here, the kinetics of nitrates consu
A team of researchers has identified 125 million hectares (309 million acres) of land suitable for agricultural expansion that won't come at the expense of tropical forests. The study argues that shifting agricultural expansion away from forests to these 'degraded lands' would avoid 13 billion tons of carbon dioxide emissions that would be released were they converted for plantations, pasture, and croplands.
