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.

Sir: When I lecture to my students on plant biotechnology I try to capture their attention by asking the question, "Why do you suppose the coca bush produces cocaine?" The answer is that it is probably an insecticide. Plants, like any other living organism, have evolved defences against their predators. These are animals, mostly insects, but also including us. This is why out of the hundreds of thousands of species of plants on the planet we can safely eat very few. Even these are the outcome of thousands of years of breeding to partially eliminate the components that do us damage. On the other side we, the survivors, have acquired immunity to some of them. Those who did not are no longer with us.

We now have much more powerful methods of removing undesirable components from our food plants by gene manipulation, and to reject what is by far our best chance of dealing with this situation because it makes a few people feel uneasy is lunacy.

The possibilities are far-reaching. One that is particularly intriguing for the ruling classes is that it may now be possible to go back to pre- phylloxera vines. The European vine was virtually wiped out in the last century by phylloxera. It was only saved because an American root stock was found that was resistant to it, and grafting continues to this day. It is potentially possible to transfer the gene for resistance to phylloxera into the European vine and, we must hope, to do away with the need for grafting. I cannot wait to see what wine buffs make of this.
