Would you eat a GMO heirloom tomato?

Brandywine tomatoes are practically the poster child for organic, heirloom produce. Knobbly, warty, and deeply flavored, they’re a far cry from perfectly round red tomatoes. At $3/lb at the farmers’ market, Brandywines are also pretty pricy.

Want to know why you have to pay so much? Brandywines are prone to nematodes, microscopic worms that destroy tomatoes from the roots up. Farmers lose a lot more of their Brandywines to disease than more modern, disease-resistant hybrids. And because they harvest less, more land and water go into producing each pound of these heirloom tomatoes. In using more natural resources than hybrids, these organic, heirloom tomatoes might actually have a larger footprint than their conventional or hybrid counterparts.

Here’s the thing: with our existing technology, we could introduce better disease resistance simply by moving a disease resistant gene from a different type of tomato into the Brandywine, in basically an accelerated version of what plant breeders have been doing for centuries. No interspecies genes, no genes from viruses or bacteria, nothing that we don’t already eat whenever we eat a non-heirloom tomato. A GMO Brandywine could use water and space more effectively and require fewer or no pesticides.

Would you eat this hypothetical GMO heirloom tomato? What if it could be shown to be lower impact than its unmodified cultivar? What if it were clearly labeled?

…and what if you didn’t instinctively flinch at the idea of GMO and everything it stood for?

I’m currently reading Josh Schonwald’s The Taste of Tomorrow, which has a provocative chapter questioning whether the schism between organic and GMO is more ideological than rational. I’m discovering that my problem with GMO is not about the actual science at all: it’s about Monsanto’s business practices, lobbying, and seed patenting. No, I don’t think making farmers dependent on a corporation is a good idea. Yes, I think the Diamond v. Chakrabarty decision that ruled that genes could be patented was a disaster.

But as far as actual genetic modification goes, I’m neutral. It’s a different, and potentially complementary, approach to solving the same problems organic farmers face: disease prevention, yield, nutrition. I’m intrigued by Vitamin A fortified golden rice that could help prevent blindness in some of the poorest areas on the planet. In China, a form of cotton has been genetically modified to contain bacteria that acts as a natural pesticide. It’s helped to reduce pesticide use by 80%. That’s a lot of pesticides that didn’t go into our ground, air, and water. In Hawaii, after ringspot virus devastated papaya trees, scientist Dennis Gonsalves developed a disease resistant GMO papaya variety, released the seeds to farmers for free, and pretty much single-handedly saved the Hawaiian papaya industry and the livelihoods of many small farmers.

Of course there are concerns with GMOs.  I think it’s perfectly legitimate to be concerned about long term effects on human and planetary health, the development of resistance to GMO, monocropping. Like you, I’m upset about the corporatization of food and Monsanto’s monopolistic policies. Although GMO produce goes through rigorous testing, we don’t always know what to test for, and it’s possible, even likely, that there will be results we could not have predicted. Increased production, for example, often triggers an increase in population/consumption (why hello, industrial animal farming), and we’re still biological creatures, after all. Increasing efficiency while decreasing consumption is the hardest challenge we’ve ever faced as a species.

But nor is organic always synonymous with sustainability. Organic tomatoes imported from Mexico are sucking local water tables dry. The organic strawberries at the farmers’ market are still spayed with pesticides that are not necessarily less toxic than synthetic counterparts. We usually think of biodegrading as a good process, but some organic pesticides degrade into toxic chemicals. Is a water-hungry, disease-prone organic plant really ‘greener’ than a GMO with higher yields that requires fewer pesticides? I don’t know.

Everything’s a compromise. Call me a bad greenie for breaking with the ‘organic = good, GMO = bad’ binary, but here’s what I think: Wrenching humanity off its current course of self-destruction and on to a more sustainable path is a big, messy, complicated problem. And ignoring potential solutions just because we’re ideologically — not rationally — opposed may not be helpful in finding solutions. It’s possible we’ll need GMO technology when the climate starts changing too quickly for our old plants and ways of agriculture. It’s possible GMO and organic could complement each other for more sustainable agriculture and stable food supplies. One thing is clear: we can’t go backwards.

What do you think about GMOs? Would you eat a GMO Brandywine?
