Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

THE WORD on everyone's lips when it comes to genetically modified food is that it is "unnatural". Why should we be forced to eat something that is the product of a scientist's sterile laboratory rather than Mother Nature? After all, our experience with BSE has shown us what can go wrong when the "experts" start messing around with the human food chain.

In fact we have been messing around with the human food chain for thousands of years. It began when the first farmers started to select strains of plants and animals that could be selectively bred under unnatural conditions to produce, eventually, the crops and livestock we are familiar with today.

By selecting the physical traits of a plant or animal - and discarding others - humans hijacked the forces of natural selection to produce what are in effect artificial lifeforms that would not exist in nature. An organically grown corn on the cob or free-range hen is no more natural than an English garden. Each is the product of human innovation.

GM is about taking this a stage further by tinkering directly with the genes of a plant or animal. This can involve the transfer of DNA from one species to another, a rare but not impossible event in nature. It means the genetic selection can be targeted, unlike the trial and error of the past. But, like any innovation, it poses new risks.

The potential benefits include crops that are inherently resistant to pests, which might mean fewer agrochemicals being sprayed on farmland. It could bring crops resistant to drought for the developing world, or more nutritious staples for an ever-expanding global population. It could also mean the countryside continues to become a monocultural desert for wildlife - including the insects and microbes that now eat 40 per cent of what we grow - which began long before the application of genetics to farming. GM technology could be a force for bad as well as good.

Which way it goes depends on what we decide to do with it and the safeguards we impose. A ban would mean we have thrown out the potential good with the possible bad.
