Genetic modification (GM, also called genetic engineering, GE) hasn’t yet done much to increase farm yields. More has been achieved by selective breeding and by other non-GM techniques, some of which are biotechnological.
So says Geoffrey Lean at the Telegraph in his thoughtful article ‘The inconvenient truth about GM’.
Anyway, as Mr Lean mentions, simply growing more food may not solve hunger. I think that’s a crucial point, sometimes ignored by those who get excited by technofixes. Edward Carr urges us to do food security differently. You can see more on this topic under my ‘food’ tag.
