Comments Off on How seaweed eating super cows will save the world

Methane is 36 times more damaging to the environment than carbon dioxide, and livestock are responsible for emitting 44 percent of the greenhouse gas around the globe. Fortunately, a team of Australian scientists discovered that adding dried seaweed to sheep and cattle feed can cut global methane emissions by 70 percent – which is the equivalent of eliminating India’s nationwide carbon dioxide emissions. Rocky De Nys is a professor of aquaculture at James Cook University (JCU), and he has been leading the efforts to develop a seaweed-infused cattle feed that could fight climate change and help save the world. The need to reduce methane emissions from livestock has been urgent for some time, and new information illustrates that the situation is becoming more dire with each passing year. In a 400-page report entitled Livestock’s Long Shadow published in 2006, the United Nations Food and Agricultural Organization evaluated the environmental damage done by the world’s 1.5 billion cattle. The study found that livestock are responsible for 18 percent of greenhouse gas emissions, and methane accounts for most of that. That means cows contribute to global warming more than cars, planes, and all other forms of transportation combined. Related: Cattle are the world’s top greenhouse gas emitters among livestock, study finds Past studies found that around 90 percent of methane from cows actually stems from their burps, rather than gaseous emissions from the other end, and the UN report confirms this. Because of that tidy little tidbit, scientists have been working for years to fidget with cows’ digestive systems in an effort to reduce those toxic burps. In 2014, experiments found that adding garlic to cows’ diets could reduce their methane emissions by 40 percent but, at the time, they hadn’t yet determined how to keep the garlic from transferring to the flavor of the cows’ milk. A study the following year tinkered with the use of a controversial hormone treatment to speed up conception in young cows, translating into more milk production per cow without the need for additional land, thereby having the effect of reducing methane emissions for small farms. That technique has so far only been used in computer modeling, and is not expected to be introduced to living cows for quite some time, if ever. De Nys and his research team at JCU tested 20 different varieties of seaweed, which is known to aid in digestion and reduce gaseous emissions even in humans. (Beans are often cooked with kombu, a type of seaweed, in order to make them less of a ‘musical fruit.’) Where cows are concerned, scientists found that the species of red seaweed called Asparagopsis taxiformis is most effective in reducing methane burps, and they have been harvesting it off the coast of Queensland to aid in their research. Using an artificial cow stomach that operates a bit like a compost bin, the research team found that a diet consisting of two percent red seaweed and 98 percent typical feed resulted in methane levels that were 60-70 percent lower than without seaweed. The JCU team is partnered with Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) to test the experimental seaweed cattle feed on living cows, and they expect the results to mirror the figures measured in the lab. Meanwhile, research scientist Rob Kinley, also with CSIRO, is working to develop methods for producing enough seaweed to supplement the feed of millions of cows. Although seaweed is a fast-growing and often sustainably harvested plant, there isn’t enough of it growing in the wild, so Kinley is looking into cultivation methods with a high yield. With any luck, the team will soon find the funding they need to move forward. “Money will decide how quickly we can move … the sooner we have more money to move forward with the research, the sooner we will be able to get it out,” Kinley told ABC North Queensland. “Three years isn’t outside the realm if we can get enough support to move with it.” Via Science Alert and ABC Images via Wikipedia , EPA/IPCC , and Rob Kinley

If you want to dramatically reduce your carbon footprint, you might want to start with your dinner plate. A new study published in the Proceedings of the National Academy of Sciences revealed that cattle are the top emitters of greenhouse gasses among livestock. The research, backed by the International Livestock Research Institute (ILRI) and the Commonwealth Scientific and Industrial Research Organization (CSIRO) found that among small ruminants, poultry, pigs, and cattle were responsible for more than three-quarters of livestock emissions.

Scientists Want to Tax Meat to Cut Methane Emissions, Slow Global Warming

Comments Off on Scientists Want to Tax Meat to Cut Methane Emissions, Slow Global Warming

A group of scientists aren’t waiting for the world to follow Al Gore’s lead by going vegan to save the planet. Instead, they want to tax meat in order to reduce livestock methane emissions , a potent short-term contributor to climate change. The 3.6 billion ruminants on the earth, mostly sheep, cattle and goats, that have increased in population by 50 percent over the last five decades are responsible for 14.5 percent of all human-caused greenhouse gas emissions . The proposed tax is expected to reduce demand for their meat and therefore help to slow global warming.

Waste From Cattle Food Plant Kills 10,000 Fish in Mexico

Comments Off on Waste From Cattle Food Plant Kills 10,000 Fish in Mexico

Cattle waste presents a huge problem for farmers. From feed to fecal matter, it has the potential to cause environmental harm when leaked into waterways, released as gas into the air, and it can infect meat during processing. On Monday in Jalisco, Mexico the Hurtado reservoir was poisoned by hundreds of liters of molasses from a nearby cattle food plant. The facility creates the sticky brown substance by refining beets and sugarcane for cows to eat. Acting without a permit, the goo flowed into a canal feeding the reservoir, asphyxiating over 10,000 fish.

Comments Off on Arizona Uranium Feared to Be Contaminating U.S. Beef Supply

Two years ago, a Navajo cattle rancher found an old uranium mine on his grazing land in Arizona. Even after the rancher  notified federal officials , who discovered that levels of radioactivity were still high, the mine near the town of Cameron is still not closed off . Meanwhile cattle still roam through the area, eat grass that is possibly tainted by uranium and in turn is auctioned off with the result that the meat is in the U.S. food supply.

Photo: Bala under a Creative Commons license . In late May, a cow named Yvonne decided not to be eaten, and broke through an electric fence to escape from the farm in Bavaria where she was being fattened for slaughter. Since then, she has been on the run. After she jumped onto a road in front of a police cruiser, Yvonne was deemed a traffic hazard by local officials, who authorized her shooting. Activists decided to come to … Read the full story on TreeHugger
