European farming’s existential crisis?

There's been a wave of farmers' protests across Europe in recent weeks. France, Germany, the Netherlands, Spain and Eastern European countries have all seen farmers airing their grievances by driving their tractors into towns and cities and blocking roads. There have also been similar demonstrations far beyond Europe, in India. Guy Hedgecoe has been looking at the protests and how some grievances are uniting farmers from different countries while others are dividing them. Because farming is so important for our day-to-day lives, the outcome could affect us all. (Picture: A farmer pours industrial honey during a protest in Madrid.
