British dairy farmers are dumping surplus milk during peak production while UK food manufacturers import palm oil to replace dairy fat in their recipes.
Palm oil wins out because it’s cheaper and more shelf-stable than butterfat, but the rainforest and peatland clearance behind it does far more damage than the swap suggests, sterilising entire ecosystems, drying out ancient carbon stores, and pushing wildlife into conflict with plantations built on their old habitat.
Most of us know the headline story about palm oil. You’ve seen the harrowing adverts about displaced orangutans, and you know rainforests get flattened to make way for plantations. It’s awful, of course, but it’s become one of those issues where people switch off because the message feels familiar.
Dig a little deeper, though, and the real picture is far messier than a few distressing images on a screen.
What got me thinking about this was a video by Ben over at Radmore Farm (They’re Replacing British Milk With Palm Oil — And You’re Not Being Told). He pointed out the sheer madness of what’s happening on our own doorstep compared to halfway across the world. In the UK, we’ve got dairy farmers with more milk than the processing plants can take, literally pouring good produce down the drain during peak flushes. Yet at the exact same time, food manufacturers are quietly reformulating recipes, replacing domestic dairy fats and butter with imported palm oil.
It’s a pure spreadsheet decision. Palm oil is cheap, shelf-stable, and kind to the bottom line.
Fair enough, businesses exist to make money. But that video sent me down a bit of a rabbit hole, and the trade-off is far worse than just swapping one ingredient for another.
What Clearing Rainforest Actually Destroys
The part we rarely hear about is what happens to the land itself when ancient tropical rainforests get cleared for commercial monoculture. Clearing ancient rainforest sterilises an entire biological engine. Losing the trees is the easy bit to picture.
A natural rainforest has four or five distinct layers, from the deep root networks right up to the canopy. It supports thousands of microclimates, complex fungal networks in the soil, and a massive web of life. Replace that with miles of identical oil palms, and you’ve effectively created a green biological desert.
The Soil and Peatland Damage Nobody Mentions
The soil takes a hammering. Young palms drink up nutrients at a blistering pace, so growers pump in heavy loads of synthetic fertilisers and chemicals just to keep the ground producing.
Then there’s the peatland issue. Clearing tropical peat swamps by digging drainage channels dries out ground that’s locked up carbon for thousands of years. It oxidises, turns into a severe fire hazard, and once the rains come, the loose topsoil washes straight into the rivers, choking local waterways with silt and chemical runoff.
Why “Pest” Animals Are Actually Starving
Even the wildlife aspect gets misunderstood. People assume native animals naturally feed on commercial palm fruit. In reality, wild animals only raid these plantations because their natural, varied larder has been clear-felled. When starving elephants or primates wander onto the plantations looking for calories, they get treated as agricultural pests.
There’s No Clean Answer Here
None of this is simple, and I certainly don’t pretend to have all the answers. Global supply chains are complicated beasts, and palm oil yields more oil per hectare than almost any alternative crop out there.
Still, you’ve got to ask yourself: when did it make sense to hollow out ancient ecosystems on the other side of the planet just to ship cheap fat across oceans, while our own farmers pour fresh milk down the drain?
I’m not calling for an all-out boycott, but it does make you pause and look a bit closer at the back of the packet next time you pick up a biscuit or a spread.
Palm Oil, British Dairy and the Real Cost Behind the Label
Why are UK food manufacturers replacing dairy fat with palm oil?
Palm oil is cheaper than butterfat and stays solid at room temperature without refrigeration, which makes it easier and less costly to work with in manufactured food. Manufacturers reformulate recipes around it to protect profit margins, even while British dairy farms are producing more milk than processors can use.
Why are British dairy farmers pouring milk down the drain?
During peak production periods, known as flushes, farms can produce more milk than processing plants have capacity to collect and process. With nowhere to send it in time, farmers are left tipping fresh milk away, even as palm oil is imported to replace dairy fat elsewhere in the food chain.
What happens to rainforest land when it’s cleared for palm oil?
Clearing ancient rainforest for palm plantations removes far more than trees. It destroys a layered ecosystem of root networks, fungal soil systems and countless microclimates, replacing it with a single uniform crop that supports a fraction of the original life.
Why is draining peatland for palm oil plantations a problem?
Tropical peat swamps store carbon that has built up over thousands of years. Draining them for plantations dries out that peat, causing it to oxidise and become a serious fire risk, while rainy season run-off washes topsoil and chemicals straight into local rivers.
Why do elephants and other animals raid palm oil plantations?
Wild animals aren’t drawn to palm fruit out of preference. They raid plantations because their natural habitat and food sources have been cleared to make way for them. Starving animals looking for calories are then treated as agricultural pests on land that was once their home.
Does palm oil produce more oil per hectare than other crops?
Yes. Palm oil yields significantly more oil per hectare than alternatives such as soy, rapeseed or sunflower, which is part of why it remains so widely used despite the environmental cost of clearing land for it.
