Organic food nutrition; Care farming; 4x4 damage

A new study published today in the British Journal of Nutrition investigates the nutritional differences between organic and conventionally-produced food. It concludes that there are differences, particularly when it comes to the percentage of beneficial Omega 3 fatty acids in milk. But does that mean it's necessarily more better for you? Caz Graham talks to two academics about what the research means.

Rangers on Dartmoor are warning that the moor is being damaged by 4x4 drivers "off-roading". They say that, after weeks of rain, the wet ground is vulnerable to erosion, and warn that several protected sites in the area have suffered severe damage.

As part of the BBC's "In the Mind" season, Nancy Nicolson explores "care farming" in the Highlands, and finds out how it helps vulnerable people - including those with mental health problems.
