Does Nature Really “Do Its Thing” on Organic Farms?

Fridge picI am lucky. My fridge is full of food: mostly produced in the UK or Europe; all nutritious, safe and affordable; and almost all produced on conventional farms, with a small amount of organic food (in my case, chocolate). Given that you’re reading this, I’ll hazard a guess that you are lucky too. 795 million other people can’t say the same thing – and feeding all the people on a planet where 1 in 9 don’t currently have enough food is, in my view, our biggest challenge.

The fact that we face this challenge makes me really irritated when celebrity chefs who could make a huge difference, bow instead to popular rhetoric. In his latest blog post, mockney chef and food pundit Jamie Oliver proclaims that “…organic food is natural food, where nature has been allowed to do its thing, and I’m sure most of us will agree that putting natural ingredients into our bodies is only going to be a positive thing.”

If we ignore the nonsensical claim that natural ingredients produce positive results (Really? Let’s examine puffer fish, solanaceae poisoning, dangerous fungi, absinthe, the many consequences of obesity…), let’s simply look at his claim that organic food is natural.  Except, well, it’s not. Agriculture first developed ~12,000 years ago, and ever since then farmers have been doing their best to breed crops and animals that are best suited to their farming system, whether it’s organic or conventional. Want dairy cows that produce high-quality milk from grazing pasture; leaner pork chops; or strawberries that can survive supermarket handling? You’ve got it. All achieved through traditional breeding techniques (otherwise known as “nature doing its thing”): noting that plant or animal A has desirable characteristics and breeding it with plant or animal B to (hopefully) produce better offspring. No scary chemicals, scientists with syringes or genes in test-tubes. Every farm in the world is founded on “nature doing its thing” – not just the organic farms. We can argue whether GMO crops are natural (breeding techniques are simply more refined and specific) or not (scientists playing god…) but that argument becomes redundant in the EU and many other regions, where GMO crops are not approved.

Can organic producers use pesticides? Yes, if they’re compounds approved for organic production (e.g. highly-toxic copper-based fungicides). Can they use antibiotics and wormers? Again yes, if a proven disease problem exists (note that rules differ slightly between the UK and USA). Are organic farmers just merrily sitting back and letting their crops cross-pollinate and reseed, and their bulls run around happily “doing their thing” to whichever cow they come across? No. It’s a beautiful bucolic image to suggest that organic farmers are happily working with Mother Nature whereas conventional farmers have an evil scientist sitting on one shoulder and a big agribusiness corporation on the other, but its simply not true.

According to Mr Oliver, “…the simple fact is that often we don’t actually have to interfere with nature.” The idea of a world where we could feed over 7 billion people without having to actually invest any research dollars into improving food production is lovely, but it’s smoke and mirrors. At the most basic level, what happens if we don’t “interfere” by controlling weeds (whether by chemicals, mechanical tillage or human labour)? Crop yields are reduced, food production goes down and we feed and clothe fewer people. What happens if a cow has problems giving birth? In nature, she dies. On a farm (whether organic or conventional) both she and the calf are saved, providing milk and meat for us to eat. According to the World Organisation for Animal Health, 20% of global animal protein losses are due to diseases for which treatments already exist – we simply need to make them available to every farmer worldwide. Just think how many more people we could feed if we interfered with nature in that way?

Huge amounts of research monies are invested each year to find ways to improve food production on both organic and conventional farms worldwide. Some are highly technical, others are simple, but all are contributing to the goal of feeding the world. Unfortunately, when food pundits jump on the “let’s promote system X” bandwagon as Mr Oliver has done with organic production, using persuasive but false arguments, we lose traction in fulfilling the real goal. Rather than arguing about which foods we can/should be buying, we need to accept that there’s a place for all systems; examine the ways in which all systems can improve soil fertility, animal health and environmental impacts; and make faster progress towards feeding the world while still enjoying our food choices.

Got Ebola? Just Take Some Vitamin C.

Ebola

It appears that the lunatics are taking over the asylum. This is another post about “things that irritate me” – just a short rant this time about bad science and fear-mongering. The current irritant is the Alliance for Natural Health (ANH; as publicized by the Organic Consumers Association), which claims that Ebola can be prevented and treated naturally, but that these remedies are being (gasp!) “ignored by doctors and the government”.

If you’re really concerned that you may catch Ebola, the easiest way to avoid it is not to have intimate contact with an infected person’s bodily fluids; but never fear, if you do, the ANH have a list of “proven” natural remedies that will stop Ebola dead in its tracks. For example, Ebola is selenium-dependant, making people who’re already selenium-deficient more vulnerable to the disease, so if you just load up with mega-doses of selenium, you’ll be fine. Equally, both silver and vitamin C are antiviral, so add these to your selenium cocktail and you won’t just be fine, you’ll be invincible!

There’s just one problem – none of these miracle remedies have actually been tested against Ebola, which ANH claim is because of government/big drug conspiracies. It’s true that increasing your intake of selenium and vitamins C, D and E should boost your immune system to a degree, but you can’t then have a long smooch with somebody who’s infected with Ebola and expect to be immune. More importantly, given the ANH’s claims of natural “treatment”, there is zero evidence that any of these purported remedies provide a cure.

Most worrying of all is the final tagline: “Alert! Write to both FDA and Congress. Ask them to review natural treatments for Ebola without the lengthy drug approval process“. This lengthy drug approval process exists to ensure that drugs are safe, efficacious and do not cause unexpected or severe side-effects. It costs drug companies millions of dollars to get a single drug to market through this process, which is required for every new drug in order to protect our health. Furthermore, “natural” chemicals are not safe or effective simply because they exist in nature. Arsenic, cyanide and mercury are all inherently natural, as are deadly nightshade and death cap mushrooms. The “action alert” above is an example of bad science and fear-mongering at its worst – a dangerous remedy that will do nothing to halt the spread of the disease – and will probably hasten the patient’s death in the process.
