Tangential to Clarkson, there's a bunch of UK farmers who vlog about their experiences. They've been getting a big boost in popularity, thanks to Clarkson's farm, and they're (politely) screaming about the effect that govrnment policy is having on their livelihoods. A good example is Harry's Farm, which is apparently just down the road from Clarkson.

This video goes over how stupid the government's food strategy is. tl;dr they effectively want to
reduce food production even while the population of the country is growing at an unprecedented rate. He points out that much of the land currently used for meat rearing is entirely unsuitable for anything else. Clarkson probably won't touch on this stuff, because it doesn't make for great TV compared to piggies and fights with the planning committee, but just by making his farm series he's giving people like this an avenue to get the word out in ways that they couldn't have before. I find it fascinating.
