Food-borne illnesses are not always home-grownscottish cows have a bum rap. For decades, the local cattle have been prime suspects behind the country s outbreaks of drug-resistant,

food-borne illnesses. But research now suggests that humans and imported foods are the real culprits.

A team of researchers compared the genome sequences of nearly 400 samples of diarrhoea-causing Salmonella enterica collected from people and livestock in Scotland.

which strains isolated from local livestock had spread to humans. But they also found that strains could spread from humans to animals."

and in imported food probably entered the country and infected animals and humans separately, then continued to evolve

including resistance stemming from the controversial practice of giving antibiotics in feed to promote animal growth.

Scotland imports most of its red meat, but the authors say that the country does not have adequate surveillance in place to determine

whether imported food is a source of new pathogens. Both Woolhouse and the authors call for Scotland

and other countries to boost the monitoring of their food supply. Lance Price, a genomic epidemiologist at the George washington University in WASHINGTON DC, says that it is not surprising that Scottish cattle are not the source of Scottish outbreaks,

"Meat sale and meat trade across borders is making it harder to control antibiotic-resistant pathogens at a local scale

the team identified the yellow warbler (Setophaga petechia) and four other species as beetle eaters. Next, the researchers combined data about bird abundance, forest cover and beetle populations from six coffee plantations.

They found that beetle-eating birds were most common at sites with lots of stretches of forest nearby,

and India are driving a global increase in meat consumption, cancelling out decreases elsewhere, according to a comprehensive study of global food consumption.

The work, published today in Proceedings of the National Academy of Sciences1, takes a detailed look at what people eat,

a metric used in ecology to position species in the food chain. The metric puts plants and algae,

which make their own food, at trophic level 1. Rabbits, which eat plants, occupy level 2. Foxes,

which eat herbivores, sit at trophic level 3. Cod, a fish that eats other fish, claims level 4. Polar bears and orcas,

which puts us on a par with other omnivores, such as pigs and anchovies, in the global food web."

"We are closer to herbivore than carnivore, says Bonhommeau.""It changes the preconception of being top predator.

The study also looked at how eating patterns have changed over time. The researchers calculated the human trophic level for 176 countries for each year from 1961 to 2009 using a data on 102 types of food from animal fat to yams compiled by the Food and agriculture organization (FAO) of the United nations. Ref. 1globally,

the human trophic level increased by 3%from 1961 to 2009, driven largely by more meat consumption in India and China.

Over 50 years, an increase in fat and meat consumption has moved us further up the food web

with the global median human trophic level increasing 3%or about 0. 06 during the period."

An organism s trophic level is calculated by summing the trophic levels of the foods in its diet and the proportion in

"A change by 0. 1 means you are eating considerably more meat or animal-based foods, says Kastner.

But changes were not uniform across the globe. Countries such as China and India, where hundreds of millions of people have lifted themselves out of poverty

However, places such as Iceland, Mongolia and Mauritania, where traditional diets are mostly based on meat, fish or dairy, have seen their trophic levels decline as they diversified their daily fare.

the environmental impact of producing meat in terms of everything from carbon emissions to water use is typically many times larger than that of producing vegetable foods.

But unlike most ethanol factories, in which yeast feeds on sugars in foodstuffs such as maize (corn) kernels,

Thousands of tonnes of corn stover the leaves, stalks and husks left over after the maize harvest are stacked already waiting

By June, the plant will begin processing the stover into ethanol, which will be blended with petrol

and can contribute to increased food prices because the maize must be grown on land that would otherwise be used for food.

Tapping the storehouse of biomass left after the harvest is much less controversial. Ethanol made from corn stover produces at least 60%less greenhouse-gas emissions than petrol,

and making it does not require any extra farmland. Brewing such cellulosic ethanol, however, is hard.

Producers must dismember large, indigestible molecules such as cellulose and hemicellulose to yield fermentable sugars. The process requires the biomass to be ground up and pretreated with acids.

A cocktail of enzymes must then be applied to chop up the tough biological polymers inside all before the yeast is added to the resulting sugars.

And cellulosic ethanol could get cheaper with more efficient stover harvesting beefier enzymes and cheaper pretreatments.

Pandas have a really ridiculous diet. Can you believe they only eat non-nutritious bamboo?

There's also tons of food for the panda to eat! My Response: Sure it's ok to include something poor in your diet.

It's not ok to make that your sole source of nutrition. Note: The panda is still capable of eating fish eggs

and a number of other foods but it can not get them in the quantities needed to survive.)

Also the panda doesn't eat any old bamboo. It is notoriously picky. It does have a relatively wide range of actual species it can eat

but most of those are not found in the areas it inhabits. To make things even worse Bamboo species will flower

or more bamboo species or its food will disappear and it will starve. Conclusion: The pandas current diet has trapped fundamentally the panda.

This has proven disastrous for countless species . However if we stop babying them and getting them all of the bamboo they want for now they still have the ability to go back to a wider diet of more widely available food.

This would allow the panda to be more energetic travel further and to different environments allowing the species to thrive.

Its entire metabolism is vastly lower than normal due to its poor diet. Even its body shape has adjusted to use less energy.

However if they were to move off of their poor diet they could get more energy

This would let them find better sources of food and adapt to more changes in their local environment.

Too many pandas too soon would mean a huge population crash as they fight for food.
