Crop diversity declining as world’s large, industrial farms look more alike, researchers find

VANCOUVER—Large, industrial farms around the world are starting to look more alike, and it’s putting both the environment and food security at risk, new research from the University of Toronto Scarborough has found.

Currently, just four crops — soybeans, wheat, rice and corn — are grown on almost half the world’s agricultural lands, while more than 150 other crops are grown on the rest, according to the study.

This is a concerning trend, said Jane Rabinowicz, a coexecutive director of USC Canada, a non-profit focused on agricultural biodiversity.

“It’s an indicator of vulnerability,” Rabinowicz said, because “the more diversity you have the more protected you are, for example, against a certain pest.”

These four crops, however, tend to be grown as large monocultures, where a single crop covers a large swath of land, often with high levels of chemicals harmful to the environment.

Adam Martin, an ecologist at the University of Toronto Scarborough and the lead author behind the study recently published in the journal PLOS One, agrees declining diversity is a problem.

“If the world’s farms start to become more homogenous, the expectation is that more parts of the world are going to be susceptible to the same types of pests or disease outbreaks or other environmental fluctuations that might impact those specific crops,” he said.

While the data Martin’s study used doesn’t show how much genetic variety there is within the types of crops planted — different varieties of corn, for example — he said previous research points to issues with a lack of diversity in genetic lineages as well.

There hasn’t been a mass loss of wheat, soybeans, rice or corn yet, Martin said.

But it could have catastrophic impacts if it happens. Those crops represent a major component of the calories consumed by people.

Martin’s study is based on an analysis of more than 50 years of data from the United Nations’ Food and Agriculture Organization, which captured changes in the crops being grown in different regions between 1961 and 2014.

Though crop diversity is declining at a global scale, Martin found it has increased on a regional scale since the early ’60s — largely because more areas in the world started growing the same things.

In North America, for instance, 93 different crops are now grown on large industrial farms compared to 80 different crops in the ’60s, he said.

That finding is more consistent with the trend Ron Bonnett, president of the Canadian Federation of Agriculture, has seen in Canada over the last few decades.

“If you take Western Canada, for instance, at one time it was predominantly wheat that was growing there. Now there’s a number of different crops,” Bonnett said.

Today, farmers may have a crop of wheat alongside peas, lentils or canola, he said.

"If the world's farms start to become more homogenous, the expectation is that more parts of the world are going to be susceptible to the same types of pests or disease outbreaks or other environmental fluctuations that might impact those specific crops," says Adam Martin, the lead author of a new study on crop diversity.

Bonnett added that farmers often try to switch up their crops on an annual basis because it helps improve soil quality and keep weeds under control. They’re also quick to adapt when a new crop variety comes out that may be less susceptible to problematic pests or diseases, he said.

But it’s on the smaller farms where most of the crop diversity lives, according to Rabinowicz.

That diversity has benefits for nutrition and the farm environment. Rabinowicz said diverse crops can attract different pollinators, for example.

She added that crop diversity isn’t just something to conserve; it is also created as new plant varieties are developed — work that farmers are actively doing today.

For a long time there has been a heavy focus on industrial farming, she said, but we are seeing the “cracks in that model.”

“We’ve seen impacts on human health, we’ve seen collapse of pollinator populations, we’ve seen environmental impacts,” she said.

For instance, there have been major concerns about the impact of neonicotinoids, a type of pesticide commonly applied to corn and soybean crops, on pollinators such as honeybees. Agricultural runoff has been cited as a major cause behind blue-green toxic algae in Lake Erie. And a years long research project by scientists in the U.S. has linked pesticides to health problems in the children of farm works, as reported by the New York Times.

Moving forward, Rabinowicz said, she wants to see more diversity, not just in crops but in the models of farming more broadly.

“Diversity is a good thing,” she said, calling it “the foundation of resilience in agriculture.”

These US entities partnered with the Wuhan Institute of Virology — time for a criminal investigation?

By

(Natural News) The Wuhan Institute of Virology from which the Wuhan coronavirus (COVID-19) is believed to have “escaped” has a number of questionable partnerships that are worth looking into in light of the pandemic.

Most of them are universities, including the University of Alabama, the University of North Texas, and Harvard University. There is also the EcoHealth Alliance, the National Institutes of Health (NIH), and the National Wildlife Federation.

While the relationships between these entities and the Wuhan Institute of Virology may be completely innocent, there is no way to really say for sure without a proper investigation. And this is exactly what Secretary of State Mike Pompeo is calling for, as is the nation of Australia.

Pompeo and the folks down under, along with millions of Americans, would really like to know the true origins of the Wuhan coronavirus (COVID-19). An increasing number of people simply are not buying the narrative that the novel virus originated in bat soup at a Chinese wet market, and this even includes mainstream media outlets like Fox News.

The only way to really determine what was going on at the Wuhan Institute of Virology, and who else might have been involved. is to open the place up for an international investigation. But communist China is against this, of course, accusing Australia of “petty tricks” and collusion with the United States.

“Overnight, I saw comments from the Chinese Foreign Ministry talking about a course of activity with respect to Australia who had the temerity to ask for investigation,” Pompeo is quoted as saying in response to China’s aggression against a proposed investigation.

“Who in the world wouldn’t want an investigation of how this happened to the world?” he added.

As the U.S. aims to get back on track economically speaking, Pompeo believes that now is the time to hold communist China, the Wuhan Institute of Virology, and whoever else may have been involved accountable for unleashing this pandemic on the world.

“Not only American wealth, but the global economy’s devastation as a result of this virus,” Pompeo further stated. “There will be a time for this. We will get that timing right.”

New U.S. analysis finds that lab in Wuhan, China was “most likely” origin of coronavirus release

(Natural News) While American Leftists and most of the Democrat Party continue to serve as apologists for the Chinese Communist regime over its role in creating and then perpetuating the coronavirus pandemic, a new U.S. government analysis concludes that COVID-19 “most likely” escaped from a lab near Wuhan city.

The Washington Times reports that the analysis cataloged evidence linking the outbreak to the Wuhan lab and has found that other explanations for the origins of the virus are not as credible.

The paper reported:

The document, compiled from open sources and not a finished product, says there is no smoking gun to blame the virus on either the Wuhan Institute of Virology or the Wuhan branch of the Chinese Center for Disease Control and Prevention, both located in the city where the first outbreaks were reported.

However, “there is circumstantial evidence to suggest such may be the case,” the paper says.

“All other possible places of the virus’ origin have been proven to be highly unlikely,” said the report, a copy of which was obtained by the Times.

ChiCom officials have claimed that the virus’ origin is unknown. However, Beijing initially stated that coronavirus came from animals at a “wet market” in Wuhan where exotic meats are butchered and sold in disgusting conditions.

Chinese officials claim that COVID-19 went from bats to animals sold in the market last year, then infected humans.

U.S. intelligence officials have increasingly dismissed that explanation, however, as attention has begun to focus on evidence suggesting that Chinese medical researchers were working with coronavirus in the country’s only Level 4 facility, which is in Wuhan.

U.S. Army Gen. Mark A. Milley, chairman of the Joint Chiefs of Staff, has said that intelligence agencies are investigating whether the virus escaped from a lab or was the result of a naturally occurring outbreak, but that analysts have ruled out reports that COVID-19 was manmade.

‘The most logical place to investigate the virus origin has been completely sealed off’

“At this point, it’s inconclusive, although the weight of evidence seems to indicate natural,” the general said on April 14, “but we don’t know for certain.”

The analysis said that the wet market explanation does not ring true because the first human diagnosis of coronavirus was made in someone who had no connection to the wet market in question. And according to Chinese reports, no bats were sold at that particular market.

At the same time, several questionable actions and a growing paper trail provide clues that the virus actually escaped from a lab, even as China begins to clamp down on those information streams.

The biggest media lies about the coronavirus: Origins, treatments and vaccines

(Natural News) If there is one thing that most everyone can agree on concerning the Wuhan coronavirus (COVID-19) pandemic, it is the fact that there is no shortage of conflicting information out there about the nature of it. And the mainstream media is certainly doing its part to steer the narrative as part of a larger agenda, using plenty of misinformation along the way.

The following are among the most commonly parroted lies about the Wuhan coronavirus (COVID-19) that aim to distort the facts and deceive you into believing falsehoods about this pandemic:

Media LIE: The virus is not man-made

From the very beginning of this thing, the official narrative was that the Wuhan coronavirus (COVID-19) came from a Chinese wet market where bats and other “exotic” animals are sold as meat. But the world later learned that it actually more than likely “escaped” from the Wuhan Institute of Virology.

The mainstream media and social media platforms went nuts trying to censor this information and even called it  “fake news.” But eventually it became undeniable that bat soup was not responsible for spreading the Wuhan coronavirus (COVID-19) around Wuhan and eventually to the rest of the world – hence why we continue to call it the Wuhan coronavirus rather than just COVID-19.

We have even seen attempts by the media machine at making the Wuhan coronavirus (COVID-19) a racial issue because there are supposedly more “people of color” coming down with it than people with fair skin, which further detracts attention away from the source of this virus.

Media LIE: Hydroxychloroquine is extremely dangerous and doesn’t work

The minute that President Donald Trump announced that hydroxychloroquine may be an effective, and very inexpensive, remedy for the Wuhan coronavirus (COVID-19), the mainstream media immediately began decrying this claim as fake news, even though Anthony Fauci himself praised hydroxychloroquine back in 2013 under Barack Obama as being some type of “miracle cure” for SARS (severe acute respiratory syndrome).

There have even been studies conducted that were designed to intentionally smear the drug as both ineffective and dangerous, though one in particular purposely left out zinc, which appears to be a critical co-factor in supporting the effectiveness of hydroxychloroquine – in other words, politics as usual.

Media LIE: Only a vaccine can save us from coronavirus

Many politicians and public health officials are parroting the lie that the only way America can come out of lockdown and go back to “normal” is to get vaccinated with some future vaccine for the Wuhan coronavirus (COVID-19) that does not even yet exist. A vaccine, we are repeatedly told, is the only thing, or perhaps some new “blockbuster” antiviral drug, that can cure the world of this scourge and make everything happy and wonderful once again.

Meanwhile, not a peep is being made about things like intravenous (IV) high-dose vitamin C, which is being successfully used in other countries to stem the tide of infections without the need for new drugs and vaccines.

By omission, nutrition is pointless

Speaking of natural approaches to overcoming the Wuhan coronavirus (COVID-19) that are being systematically ignored by the mainstream media and most in politics, have you heard anyone mention the importance of nutrition in all of this? We did not think so, and this is intentional.

Regular readers of this site over the years should know by now that the single-most important thing you need to do to stay healthy besides exercising regularly is to feed your body the nutrition it needs to naturally ward off illnesses, including those associated with the Wuhan coronavirus (COVID-19).

Research compiled by the Lewin Group reveals that nutritional remedies such as calcium, vitamin D, folate, omega-3 fatty acids, lutein, zeaxanthin, and more all play a critical role in fortifying the immune system, which, if properly nourished, should have little problem fending off disease.
