#Reducing waste of food: A key element in feeding billions more peoplefamilies can be key players in a revolution needed to feed the world
He described that often-invisible waste in food--4 out of every 10 pounds produced in the United states alone
It also will require action to reduce a terrible waste of food that gets too little attention.
That waste can occur due to spoilage from improper storage of grain during transportation or from pests.
or spoil 20 percent of the world's food supply due to contamination with their urine and feces.
and then passed back into the environment through feces. By not needing its envelope to survive outside the host the virus gains the ability of non-enveloped viruses to survive longer
The pollutants products of fossil fuel combustion are emitted by cars trucks and buses. Pollutants rise up into the atmosphere
and accumulate until being washed down as wet deposition by rain or snow or as dry deposition between rain events.

#Logging debris gives newly planted Douglas-fir forests a leg-upthe downed limbs and other woody debris that are inevitable byproducts of timber harvest could be among the most important components of postharvest landscapes according to a new study led by the U s. Forest Service's Pacific Northwest Research Station.
Researchers found that retaining moderate levels of logging debris also known as slash helped to both directly
and indirectly increase the growth rate of Douglas-fir seedlings replanted after harvest. The findings which are among the first to speak to the benefits of second-growth logging debris are published online in the journal Forest Ecology and Management.
At levels typically left after forest harvesting where 40 percent of the ground is covered by logging debris we found that debris inhibited the growth of competing herbaceous vegetation
and so preserved soil water said Tim Harrington a research forester with the station and the study's lead.
This means that just leaving typical levels of debris in place after forest harvesting helps new Douglas-fir seedlings to become established.
The findings are based on a study of seedling development under three levels of logging debris--0 40 and 80 percent cover--at two sites in Washington
Harrington and his colleagues expanded on previous research on logging debris effects by increasing the number of seedlings studied extending the study period to four years and looking at the responses of additional variables like vegetation abundance
In addition to having a vegetation control effect the retained woody debris helped promote Douglas-fir seedling growth by reducing evaporation;
However where the use of herbicides to control competing vegetation was combined with logging debris seedling growth rates were observed the highest in the study especially where debris cover was 80 percent.
But these new findings suggest that long-term forest productivity will benefit from debris retention indicating much broader applicability of the research Harrington said.
and blood and urine samples were taken also. The samples collected were sent back to the UK to be analysed for their levels of selenium.
Similarly the women of the Zombwe region had less than half the levels of selenium in their blood and about one-third of the levels of selenium in their urine than that of their Mikalango counterparts.

#The lifetime journeys of manure-based microbesstudies at the U s. Department of agriculture (USDA) are shedding some light on the microbes that dwell in cattle manure--what they are where they thrive where they struggle
and others to study how livestock diet affected the transport of pathogens in field runoff from manure-amended soils.
The scientists added two types of manure to experimental conventional-till and no-till fields at 1-2-or 4-year application rates.
The manure had been collected from livestock that had consumed either corn or feed with wet distillers grains.
Gilley also conducted an investigation into how standing wheat residues affected water quality in runoff from fields amended with 1-2-or 4-year application rates of manure.
The team also observed that runoff from fields amended with 4-year application rates of manure had significantly higher levels of total phosphorus
and dissolved phosphorus than fields amended with 1-year or 2-year manure rates. Results from these studies have been published in Foodborne Pathogens and Disease Applied and Environmental Microbiology and Transactions of the ASABE.

#Exposure to pesticides in food, air and water increases risk of type 2 diabetes, study findsa study led by the University of Granada reveals that there is a direct relationship between the presence of Persistent Organic Pollutants
A study conducted at the University of Granada has revealed that there is a direct relationship between exposure to pesticides (Persistent Organic Pollutants CPOS) in food air and water and prevalence of type 2 diabetes in adults regardless
However adipose tissue can store potentially harmful substances such as persistent organic pollutants (COPS. This makes COPS concentrations a useful marker of a subject's exposure to COPS.

which control the atmospheric distribution of many short-lived climate pollutants such as tropospheric ozone methane and aerosol particles.
Because changes in these emissions affect both warming and cooling pollutants she noted. Unger said the findings do not suggest that increased forest loss provides climate change benefits
and their manure also releases this potent greenhouse gas. Greenhouse gas emissions associated with producing the U s. diet are dominated by the meats category according to Heller and Keoleian.
You won't find high potassium in junk food. Some foods high in potassium include white and sweet potatoes bananas and white beans.
If you improve the efficiency of postharvest handling you reduce waste and losses and that improves sustainability Brecht said.
These are findings of a new study that looked at the agricultural effects in 2005 of high concentrations of ground-level ozone a plant-damaging pollutant formed by emissions from vehicles cooking stoves and other sources.
However carbon dioxide is essentially a waste product with little immediate commercial value and large treatment costs.
In terms of procedure Valdemar Espinosa explains that the first step is to get the diapers only those containing liquid waste.
and get their crops to markets with far less cost and waste. The good news is that there are still expanses of the world where agriculture can be improved greatly without large environmental costs said Dr Nathan Mueller of Harvard university USA.
Traditionally carnivore diet is determined by examining samples of fresh faeces. Faecal samples only provide a snapshot of the diet based on the detected hair and bone samples of prey animals.
whether they were still suckling a litter or not says Ms Weaver. We've shown that piglet weaning age should be able to be increased with sows still producing the average 2. 4 litters a year.
This is very important to the pig industry and should lead to improvements in post-weaning growth and the welfare and survival of piglets.

The study considered four pollutants for which the U s. EPA has established air quality standards: nitrogen dioxide ozone sulfur dioxide and particulate matter less than 2. 5 microns (PM2. 5) in aerodynamic diameter.
#New perspective on agricultural plastic, debris burning, and air qualityto reduce fire hazard in the United states wildland managers often utilize the silvicultural practice of mechanically cutting woody shrubs and suppressed trees (ladder fuels).
These cuttings and other post-logging debris are burned then during periods of low fire danger
and minimize hazardous air pollutants managers often cover all or part of the debris pile with low-density polyethylene plastic commonly referred to as agricultural plastic in order to keep water out.
A recent study published in the Journal of the Air and Water Association shows that inclusion of agricultural plastic in debris piles has no effect on smoke emissions.
Co-author Dr. David Weise research forester from the U s. Forest Service Pacific Southwest Research Station at Riverside Calif. designed
The controlled laboratory study simulated debris piles that contained agricultural plastic in varying amounts to see
Based on the results of this and previous studies and literature reviews including the small amount of agricultural plastic in silvicultural debris piles as is practiced currently does not appear to affect the emissions produced under optimal burning conditions.
This study supports the hypothesis put forth a decade ago that burning agricultural plastic in debris piles would not add significantly to the emissions from a debris pile.
This research provides a key piece of information for wildland managers using on site burning to dispose of accumulated forest debris in a safe manner under favorable conditions with limited impact on air quality visibility
This means the observed increase in the rate of soil respiration accompanying rising temperatures is released due to carbon dioxide by the an uptick in the amount of litter falling on the forest floor and an increase in carbon from underground sources.

The pollutants from urban stormwater runoff can harm fish and wildlife populations foul drinking water and make recreational areas unsafe.
and plant uptake can remove pollutants. Typically the gardens are excavated backfilled with a filter bed substrate then planted with vegetation that helps to remove pollutants.
The filter bed substrate is the foundation of the rain garden and gives it the ability to infiltrate runoff slow drainage support plant growth
and remove pollutants explained Helen Kraus lead author of a study published in Hortscience. Kraus and her colleagues designed experiments to assess three different filter bed substrates for their effectiveness in nutrient removal and supporting plant growth.
Results showed that sand had good overall retention of pollutants except nitrogen. Soil had the lowest remediation of phosphorus
and phosphorus. Overall all three substrates functioned in reducing the quantity of pollutants in urban stormwater runoff the authors noted.
Other possible places to get microbes include leaf surfaces the soil or feces that woodrats collect from other animals.
Woodrats naturally eat their own and other woodrats'feces. So in the experiment juniper-eating Great Basin woodrats were fed rabbit chow mixed with feces either from other juniper eaters or from creosote-eating Mojave woodrats.
Both woodrat groups then were challenged with a creosote diet. After ingesting feces --and thus gut microbes--from creosote eaters juniper eaters persisted for 11 days on the creosote diet without losing much weight.
Yet 65 percent of the juniper eaters that ate feces of other juniper eaters didn't gain microbes that detoxify creosote
so they lost 10 percent of their weight by day 11 on a creosote diet.
They ate as much as the woodrats that were fed feces with creosote-detoxifying microbes. Instead Kohl and co-authors found that
when woodrats didn't get transplants of creosote-detoxifying microbes their urine was more acidic suggesting their livers expended a lot of energy to degrade creosote toxins.
But in juniper eaters that consumed the feces of creosote eaters their newly acquired gut microbes likely detoxified most of the creosote taking the burden off of liver enzymes.
It can also be transmitted through semen urine and feces and even milk. Identifying variationsin 2003-2004 the Antelope research station in northwestern South dakota bought 136 cattle and wound up with 60 persistently infected calves.
The key seems to be how plant litter chemistry regulates the soil biological activity that facilitates the buildup composition and stability of carbon-trapping organic matter in soil.

#Broccoli sprout beverage enhances detoxification of air pollutants in clinical triala clinical trial involving nearly 300 Chinese men
and women residing in one of China's most polluted regions found that daily consumption of a half cup of broccoli sprout beverage produced rapid significant and sustained higher levels of excretion of benzene
It acts to increase enzymes that enhance the body's capacity to expunge these types of the pollutants.
Urine and blood samples were taken over the course of the trial to measure the fate of the inhaled air pollutants.
The research team found that among participants receiving the broccoli sprout beverage the rate of excretion of the carcinogen benzene increased 61%beginning the first day and continuing throughout the 12-week period.
In addition the rate of excretion of the irritant acrolein rapidly and durably increased 23%during the 12-week trial.
The clinical trial targeting prevention is notable in that it evaluated a possible means to reduce the body burden of toxins following unavoidable exposures to pollutants.
