Alf Young (Comment, The Herald, April 25) rightly calls into question "the old certainties".
Staple foods such as grain are not simply an industrial raw material. Even before the current crisis, more than 800 million people went to bed hungry each night. Now food riots are spreading across the globe. Yet barely half of the world grain harvest goes to feed people. More than one-third goes to feed the burgeoning world herd of farmed animals. But most of the food value in grain - including the protein - is lost when it is eaten second-hand as meat.
The time has come to reject industrial animal farming, which is a food destruction process, not a food production process. Those of us living in rich countries should lead the way. A typical British diet uses land that could feed three vegans, including land in countries where people suffer from malnutrition. By choosing to eat a balanced, exciting plant-based diet, we can stop artificially breeding farmed animals. That will free up large quantities of food, so we can stop importing staple foods from abroad. The choice is between breeding and feeding farmed animals, or feeding hungry people.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
