Germany is home to 83 million people. But that isn't the country's total population: It's also home to about 27 million pigs, 12.6 million cattle, and nearly 40 million egg-producing hens. Their lives are very hard.
New lab experiments suggest that increasing ocean acidification could take a big bite out of the economically important cod fishery in the North Atlantic. The research suggests that the buildup of CO2 in the ocean could double the mortality of newly-hatched cod larvae.
Members of the German research network BIOACID quantified the impacts, showing that recruitment could decrease to levels of one quarter to one twelfth of the recruitment of the last decades. Cod have already been under intense fishing pressure for decades, and the new study, published in the online journal PLOS ONE, identifies climate change as an emerging new threat.
The Washington Department of Fish and Wildlife said it has killed six wolves in the Profanity Peak Pack. Members of that pack are blamed for at least 12 cattle kills in the northeastern part of the state.
James Cook University's Prof. Bill Laurance has taken part in a study to map the ecological effect of people on the planet. He said the news isn't great.
"The most species-rich parts of the planet—especially including the tropical rainforests—have been hit hardest. In total, around 97 percent of Earth's biologically richest real estate has been seriously altered by humans," he said.

As if toxic waste from chemical manufacturing and other industrial processes weren’t enough, scientists say some streams are also being fouled by remnants of amphetamines — in some cases at high enough levels to alter the base of aquatic food chain.
A new study, published in the journal Environmental Science & Technology, traced the presence of illicit drugs at six stream sites around Baltimore, focusing on the Gwynns Falls watershed, which is part of the Baltimore Ecosystem Study Long-Term Ecological Research program. Two rural streams were also sampled in the Oregon Ridge watershed, the closest forested region.
“Around the world, treated and untreated wastewater entering surface waters contains pharmaceuticals and illicit drugs that originate from human consumption and excretion, manufacturing processes, or improper disposal,” said lead author Sylvia S. Lee conducted the work as a postdoctoral researcher at the Cary Institute of Ecosystem Studies. “We were interested in revealing how amphetamine exposure influences the small plants and animals that play a large role in regulating the health of streams,” said Lee, now with the EPA.
Researchers with the UK’s Centre for Ecology and Hydrology have released a new study linking neonicotinoid pesticides with a long-term decline of wild bee species.
The study, published in the journal Nature Communications, analyzed changes in the population of 62 wild bee species, comparing them with patters of oilseed rape crops between 1994 and 2011, as the use of commercial use of neonicotinoids became widespread.
The findings suggest that systemic pesticides contributed to a “large-scale and long-term decline” in wild bee species distributions and communities. Species that regularly forage on treated rape fields declined, on average, three times as much as species that feed on a wider variety of plants, showing that oilseed rape is a principle mechanism of neonicotinoid exposure among wild bee communities.
Neonicotinoids are applied to seeds before planting. The active compound is spread throughout the plant, which means insects ingest the chemical when they feed on the pollen and nectar of treated crops.
The exposure resulted in local extinctions of some species, the researchers said.
ASHTON HAYES, England — This small village of about 1,000 people looks like any other nestled in the countryside.
But Ashton Hayes is different in an important way when it comes to one of the world’s most pressing issues: climate change. Hundreds of residents have banded together to cut greenhouse emissions — they use clotheslines instead of dryers, take fewer flights, install solar panels and glaze windows to better insulate their homes.
The effort, reaching its 10th anniversary this year, has led to a 24 percent cut in emissions, according to surveys by a professor of environmental sustainability who lives here.
Climate experts are meeting in Geneva to consider how to keep to the warming limits agreed last year in Paris. But with the planet breaking temperature records, scientists warn we may soon overshoot the target.
Agriculture uses an estimated 70% of the freshwater withdrawals globally and 40% of freshwater withdrawals in the United States. With severe droughts, shrinking reservoirs, and freshwater shortages in some areas of the US, water conservation is as important as ever for farmers. Here are 10 water conservation ideas that can minimize water waste. If you have another farm water conservation tip, please share it below in the comments.
We've used up more resources than the planet can regenerate in a whole year - and it's only the start of August. Mathis Wackernagel of the Global Footprint Network explains why we need to check our overconsumption.
Colorado Governor John Hickenlooper says a “shifting climate” threatens many of the state’s vital industries, including skiing and agriculture, and he wants the state’s power plants to cut greenhouse gas emissions by 35 percent in the next 15 years from 2012 levels. The goals are outlined in a draft version of an executive order on mitigating and adapting to climate change, which spells out some specific threats of global warming that are already well-known, including:
Wildlife presents a similar challenge for hunters and photographers, but because of range limitations, photography compares best with archery. So, teach gun safety and use the gun on cans, bottles, and targets, but use the camera on wild animals.
The Kaqchikel women—one of 23 Mayan cultures in Guatemala—are fighting to protect their collective intellectual property rights to their traditional Mayan textile designs. Led by the Women's Association for the Development of Saquatepéquez (AFEDES), an organization with a membership of more than 1,000 indigenous women and supported by an association of Mayan lawyers, hundreds of Kaqchikel women artisans of all ages took their case to the Constitutional Court in Guatemala City this past June. They are asking the court to push the Guatemalan Congress to enact new laws that would protect their intellectual property rights over the intricate woven designs that have become ubiquitous in the tourist markets and are a direct reproduction of their heritage and cultural identity.
A new study out today from Johns Hopkins in Environmental Health Perspectives revealed associations between fracking and various health symptoms including nasal and sinus problems, migraines and fatigue in Pennsylvanians living near areas of natural gas development. The study suggests that residents with the highest exposure to active fracking wells are nearly twice as likely to suffer from the symptoms.
"This was retail politics and oil lost," was how Adrienne Alvord of Union of Concerned Scientists summed up the stunning environmental victory Tuesday in the California legislature, a victory which cemented the state's commitment to a 40 percent reduction in climate pollution by 2030.
The Musgamagw Dzawada’enuxw, whose traditional lands includes much of the Broughton Archipelago, have boarded two Japanese-owned fish farms and delivered eviction orders to remove their operations from unceded territories over the last six days.
UNESCO is proposing adding sites in the high seas to the World Heritage List. These natural wonders are in international waters. Heritage status could help protect them against pollution and overfishing.
Neonicotinoids, a widely used class of insecticide, are suspected of harming honeybee populations. But there is growing evidence that they might also have detrimental effects on other important pollinators.
To meet growing demand for food, Cambodian farmers have been increasingly resorting to the use of chemical fertilizers and some banned pesticides. But many are concerned about their negative effect on public health.
Animals like gorillas and chimpanzees are closely related to humans. But they have no rights. Peter Singer, a professor of bioethics tells DW why great apes should be legally recognized and why animal interests matter.
