Megafarm/Environmental Harm?

 

Plans for a Norfolk megafarm have been rejected by local councillors, citing environmental concerns. It was intended to establish one of the largest industrial poultry and pig units at Cranswick. The unit would have had 900,000 chickens and pigs (https://www.theguardian.com/environment/2025/apr/03/plan-for-norfolk-megafarm-rejected-by-councillors-over-environmental-concerns). That’s an awful lot of animal shit. Not only would the smell be overpowering, there would be a real danger of eutrophication in any surrounding waterbodies. Faeces are nitrogen rich and, when washed into rivers, streams and even the sea, stimulate rampant algal blooms. This rapidly removes oxygen from the water, producing dead zones. This seems one case where profits and ‘additional jobs’ haven’t overridden environmental concerns!

Conditioned to See the Upside of Climate Change?

 

Banks appear to be employing some simple-minded folk. Some of their 'gurus' are reporting that climate change will be a boost to the manufacturers of air conditioning. There may well be increased local demand for such units in hotter areas of the developed world. Not everyone, however, will be able to purchase a new air conditioner. Furthermore, running these devices will require more electricity that could well exacerbate global heating. Climate change, also doesn't mean uniform alterations in the prevailing weather. Extreme weather events are likely to disrupt the ability to maintain a comfortable room temperature (https://www.pressreader.com/uk/the-guardian/20250403/282067692749452). This kind of statement reminds me of earlier claims. It was suggested that climate change would expand wine production into northern areas of the UK. The BBC even suggested a benefit would be enabling children to play outside longer. It isn't even April 1st!

And a Partridge In a Pear Tree?

 

Turtle doves, pair for life. These birds fly annually, from sub-Saharan Africa, to breed in northern Europe. As they crossed this continent, they were shot for sport, especially Spain and Italy. As the Turtle dove was classed as vulnerable, a temporary hunting ban was imposed by the EU in 2021. It's now been agreed that 132,000 Turtle doves can again be shot by hunters, as they cross Europe. The EU argue that the species has shown a remarkable 25% increase in its western population. Hunters are ecstatic, as they make lots of money from this annual event (https://www.birdlife.org/news/2025/04/01/press-release-european-commission-gives-green-light-to-reopen-hunting-season-for-turtle-dove/). The Turtle dove is currently the fastest declining UK bird species. Lifting the European shooting ban, is likely to drive the species to extinction in this country. One more present that can't be delivered in 'The Twelve Days of Christmas'? 

Too Big For Their Boots (Trunks)

 

More than 1 million cars sold annually in the UK are currently too big to fit into a typical parking space. There are now suggestions that SUVs should face higher charges as they are outgrowing town and city centres. Most people seem to buy them as status symbols. It’s suggested that small, electric cars should be encouraged for city use. It would be better, however, to ensure that public transport is fast, efficient, clean and cheap (https://www.theguardian.com/environment/2025/apr/04/more-than-1m-cars-sold-in-uk-each-year-too-big-to-fit-typical-parking-space). Some folk need to use cars in towns and cities but SUVs are rarely a requirement there. The parking spaces could be used to create more people and environmentally friendly locations.

Hitting the Spot?

 

Health records of more than 280,000 older Welsh adults have been examined. From 1st September 2013, Welsh public health policy ruled, that folk born on or after 2nd September 1933, were eligible for a shot of the Zostavax vaccination to protect them from shingles. Older subjects missed out. This distinction generated a natural experiment. When the data was analysed, subjects receiving the vaccination, showed a 20% reduction in their risk of developing dementia. The Zostavax vaccination has now been largely discontinued. This finding provides the strongest evidence yet that this vaccine reduces dementia risk   (https://www.theguardian.com/society/2025/apr/02/study-finds-strongest-evidence-yet-that-shingles-vaccine-helps-cut-dementia-risk). This fortuitous finding doesn't, of course, suggest a clear mechanism for Zostavax's protective effect on dementia. The vaccine was designed to protect individuals from a recurrent viral infection inflaming nerve endings. Perhaps it has wider effects on the brain?

Best For the West?

 

The UK is the most nature-depleted European country. Compared with the rest of Europe, the UK is very  under-forested. In England, tree cover is only 12.8%. Currently England's only national tree forest is in the Midlands. There's now a plan, however, funded by government and charities, to plant 20 million trees in 2500 hectares of the West of England. When completed in 2050. this new national forest, will  incorporate parts of Wiltshire, Gloucestershire and Somerset, as well as the city of Bristol. It will be a forest in the Medieval sense, with a mosaic of habitats. Its area will feature grassland; farmland; towns and villages as well as densely-planted, closed canopy woodland. It will try to dispel the myth that forests ands farming are incompatible  (https://www.theguardian.com/environment/2025/mar/21/new-western-forest-england-20-million-trees-2050). A Western national forest would benefit both people and wildlife. It would certainly help counter the effects of the greenhouse effect on climate change. Forests absorb and store carbon dioxide as well as providing shade. The forest could also boost tourism within its confines. More of this type of development is needed in the UK. The forests need, however, to be mixtures of different tree species rather than forestry monocultures.

A New African Savannah?

The Christon 'Heart of Africa' development, which started in 2022, looks to be very substantial. This £28m, 9 hectare project near the city of Chester, is apparently intended to replicate the African savannah of Uganda and Kenya. It will have 57 African species, including antelopes, giraffes, meerkats, Naked mole rats, ostriches, rhinoceros, vultures and zebras. There will be warming stations for some animals likely to feel the cold  (https://www.bbc.co.uk/news/articles/cdxqx156r13o). By zoo standards, Christon has a very large area and limits itself to animals from a distinct location. It isn't, however, anything like the African savannah. The area is, by African standards, miniscule. There's no possibility of large-scale migrations. No big predators (e.g. lions, cheetahs, hyenas etc.) are, for obvious reasons, included. There will, consequently, be no natural population control. Humans will be in charge. Having said all this, it does seem an interesting development.

Watering Down

Thames Water has selected KKR as its 'preferred partner'. This New York-based private equity company, could take a £4bn stake in the company. Thames Water is a privatized English Water company, that has, over decades, greatly mismanaged its finances. It spent much of its income on shareholder payments and rewards to its CEOs. It also illegally pumped out untreated sewage into rivers and the seas to save money. Very little of Thames Water's profit was spent on necessary, new infrastructure. The company also borrowed money, to artificially inflate its shares. Thames Water is now keen to charge its customers more, so it can  finally get round to mandatory infrastructure updates  (https://www.reuters.com/world/uk/uks-thames-water-names-kkr-frontrunner-equity-raise-2025-03-31/). This may well be an attempt, to stave off renationalization by Thames Water. They could be hoping that KKR's 'investment', given the current anti-environmentalism evident in the US, makes it more difficult for the UK government to bring this monopoly back into public ownership (where it belongs). 

A Lawn Isn't Just For Christmas?

Like a pet, a lawn has to be kept year-round. The immaculate UK lawn of yesteryear, has now gone out of vogue. Celebrity gardener, Monty Don, is consequently working with the Royal Horticultural Society to design a hardy 'robust lawn' for the coming Chelsea flower show. Its resulting grassy area, is intended to be occasionally mown but still be resistant to trampling by dogs. A working formula, consists of combining a hard-wearing rye grass variety with daisies, clover and dandelions. The intention is to produce areas usable by humans and their pets but that also support insect pollinators, such as bees and butterflies  (https://www.inkl.com/news/rhs-develops-robust-lawn-that-works-for-people-pollinators-and-pets). The old, monocultured lawns basically suppressed many other organisms. The hope is that these robust lawns will facilitate biodiversity. Any lawn, however, is better than gardeners replacing their grass with hard-standing for cars. This makes areas more flood prone, as drainage is prevented.

After the Fall

 

Adults, when reaching 65, tend to fall once a year (like leaves). Risk of falling is increased by both internal and external factors. Internal factors include drops in blood pressure, often linked to medication or dehydration. Low blood pressure can cause dizziness, blurred vision and even fainting. These all increase the risk of falling. Getting up too quickly from sitting or laying positions can also increase the chances of a fall. External factors include uneven pavements (sidewalks) or steps. Most falls occur in the home, a place often littered with risks. If a person falls, chances of a subsequent fall are magnified. Folk can reduce their risk of falling. They can have their balance and strength assessed. Being able to stand on one foot for at least 6 seconds, dramatically reduces risk. Inactivity increases the probability of a fall. For example, walking slower than 1 metre/second increases the likelihood of falling. Simple and relatively cheap modifications can be made to homes. This can include improving lighting, putting in strategic hand rails, shower chairs etc. Folk also need to be educated on how to safely get up after falling. In the home, this may involve crawling to a sturdy piece of furniture. Fallers may need subsequent medical assessment  (https://www.theguardian.com/global/2025/mar/31/falling-how-to-avoid-and-what-to-do). I was told, several years ago, that the most dangerous activity in the house is putting on a pair of trousers or tights.

Going to the Seeds?

 

The seeds of many plants are rich in oils. These oils provide plants with the energy for germination. Sunflower; soya bean; corn; grape seed; rice bran; sesame and safflower oils are marketed as 'Vegetable oils' in the UK and 'Canola' in the US. The current US Health Secretary has swallowed many of the conspiracy 'theories' about seed oils. He claims that the US population is being 'unknowingly poisoned' by seed oils. He advocates folk reverting to 'traditional' fats (butter; lard and beef dripping) for better health. He even suggests that the current obesity epidemic can be linked to increasing seed oil in the diet. These conspiracy 'theories' have claimed that hexane, used along with pressing, to extract some oils, persists in the sold products. It doesn't, as it's easily removed. It's also maintained that seed oil lineoleic acid  is 'inflammatory'. This is simply untrue. In deed, a study showed that replacing a spoon of butter by rape seed or soya bean oil, reduced death risk by 17%. This substitution also reduced cancer risk. Since the 1950's seed oils have been increasingly used in human diets. Over the last 70 years, the use of seed oils has increased 200 fold.  Claimed associations with ill health are, however, generally correlational rather than causal. There's been many changes in human diets over this period. Seed oils only appear to be problematic, when converted, by adding hydrogen, into trans-fats. This is the case in the production of some margarines and many 'ultra-processed' foods  (https://www.theguardian.com/science/2025/mar/29/rfk-jr-says-they-are-poisoning-us-influencers-call-them-unnatural-but-what-is-the-truth-about-seed-oils). The elephant in the room is the distinction between saturated and unsaturated fats. The 'traditional' fats are saturated with hydrogen, making them solid at room temperature. Seed oils are unsaturated, making them liquid at room temperature. Saturated fats greatly increase the risk of arteriosclerosis. Arteriosclerosis is the build up of plaque on blood vessel interiors. These occlusions interfere with blood flow, increasing the probability of clotting. Coronary heart disease and stroke risks are correspondingly increased. Replacing seed oils by butter, lard and beef dripping, will consequently increase ill-health and premature death.

Bringing Them to 'Eel?

 

The migratory European eel (Anguilla anguilla) is on the red list as a critically-endangered species. In spite of this, for 50 years, the UK Glass Eels Company have exported these transparent larval eels from the Severn estuary to Kaliningrad  (Russia). Glass eels are the earliest stage that hatches from eggs and  transform into elvers (the next developmental stage) as they return to the ocean. European eels are thought to mature in the Sargasso sea before returning to the river left by the glass eel. In 2024, the UK company exported circa 3 million glass eels to Russia. These were supposedly to help a reintroduction programme in the river around Kaliningrad. Glass eels are, however, a delicacy in some restaurants. Fifty years is also a very long time for a reintroduction programme. The UK government has finally banned the export of eels to Russia. What took them so long? (https://www.theguardian.com/environment/2025/mar/28/export-of-endangered-eels-to-russia-ends-after-uk-government-ban). Red-list species need all the help they can get! The UK ban only seems to have materialised after extended pressure from environmental groups.

Slaaping Down Greenpeace?

 

Steven Donziger was an observer at the recent Greenpeace trial in North Dakota. Greenpeace were accused of being responsible for  losses incurred by the Energy Transfer Pipeline Company. That company wanted to build their Dakota Access pipeline partially across ancestral land owned by the Standing Rock Sioux Tribe. The pipeline was intended to carry crude oil from the Bakken oil fields in North Dakota, to Patoka in Illinois. The Standing Rock Sioux and environmentalists were concerned about the strong possibility of contamination to water courses. Greenpeace were briefly consulted about organising peaceful opposition to the pipeline. After what some expert observers have described as "the most  unfair trial ever initiated", Greenpeace have been fined $667 m. Energy Transfer Pipeline Company executives have effectively admitted that the trial was a SLAPP. They claim they were sending a message to Greenpeace. A 'Strategic Lawsuit Against Public Participation' is a device used by rich companies/individuals, to effectively deter their opponents by threatening them with bankruptcy. This dubious ruling has  been described as "a direct attack on the climate movement, indigenous peoples and the first amendment" (the right to free speech). SLAPPs have been used to try to prevent journalists revealing the truth about rich folk. This appears to be a really bad case of their current effectiveness  (https://www.theguardian.com/commentisfree/2025/mar/28/greenpeace-verdict-pipeline-north-dakota). It's strange how opponents to the climate movement are very selective in their interpretation of  the US's first amendment. The law shouldn't be used to encourage them. Legal costs and the lengths of trials, however, make it a very effective device. Perhaps the practice of law needs to change?

Vaccine Cuts to the World's Poorest?

 

The cuts in USAID will have devastating effects on vaccination programmes in many parts of the world (https://www.theguardian.com/us-news/2025/mar/26/trump-vaccine-aid-funding). These cuts come hot on the heels of the UK's  aid budget, to pay for increases in defence spending (https://www.theguardian.com/global-development/2025/mar/05/cross-party-group-of-mps-express-deep-concern-over-cuts-to-uks-aid-budget). A study in Lancet HIV estimates that almost 3 million more folk will die before 2030 as a consequence of these and other aid cuts. These cuts will also impact on vaccination programmes for malaria and tuberculosis in children. Reducing vaccination programmes won't just impact on countries in the developing world. Failure to vaccinate will provide pathogens with opportunities to spread to developed nations via tourism. Climate change will also bring these infectives (and their vectors) nearer.

The Best Thing to Do With Oyster Mushrooms?

Feral Miniature Dachshund

 A Miniature dachshund (Valerie), that escaped in 2023 from a campsite on Kangaroo Island (Australia), is apparently still at large some 18 months later. Folk appear to be amazed at the resilience of the little (4 kg) dog, who reportedly rarely went outside. Valerie seems impossible to catch. Dogs, however, are very resourceful, opportunistic animals. It's thought that she may be surviving on road-kill and dam water (https://www.msn.com/en-au/news/australia/experts-amazed-at-survival-of-valerie-the-miniature-dachshund-on-the-run-on-south-australian-island-for-more-than-a-year/).This story reads like an adventure yarn. It's generally not a good idea, however, to have companion animals roaming the Australian scrub. Dogs (and cats) can constitute problems for indigenous wildlife. 

If Space Is Your Oyster?

 

The Fram2 SpaceX mission will carry an an Oyster mushroom culture into space. These fungi, grown in microgravity, will be compared to counterparts remaining on the ground in Florida. Mushrooms require no special fertilizers and relatively little water. Each day, they also double in size. Mushrooms, especially when exposed to UV light, are one of the few foods, naturally containing Vitamin D. This vitamin is important for astronaut bone health, compromised by weightlessness. Mushrooms are good sources of potassium (as are vegetables) but also of selenium and copper (found in nuts and seeds). Growing them in space, could provide astronauts with a reliable, nutrient-dense food source  (https://www.theguardian.com/science/2025/mar/26/perfect-space-crop-australian-company-to-attempt-to-grow-first-mushrooms-in-orbit). It's obviously important to establish potential sources of fresh food, especially for longer space flights. Oyster mushrooms appear to have lots of potential. Anyone can grow them in kitchen kits! 

It's Not Tackling Climate Change That's Going to Cost an Arm and a Leg!

 

Critics of net zero policies often rail against their costs. A joint Organization for Economic Cooperation and Development and UN Development Programme report, however, notes that one third of global GDP could be lost this century if the climate crisis is allowed to run unchecked. The report concludes that taking strong action to tackle climate change will increase economic growth rather than damage a country's finances. It predicts a net gain of 0.23% by 2040.  The report also notes the gain would be greater by 2050, if one adds the benefit of avoiding the devastation caused by runaway climate change. Benefits would be seen in both advanced economies and in lower income countries (https://www.theguardian.com/environment/2025/mar/26/tackling-climate-crisis-will-increase-economic-growth-oecd-research-finds). A problem has been the seductive power of politicians who can't (or won't, because they can see votes in it) see the difference between running the economies of a country and that of a household. Add to the equation the well-financed propaganda of consortia who benefit from fossil fuels, and you have the conditions for stasis. 

A Plague On All Your Houses!

 

The UK Health Security Agency (UKHSA) has named 24 microorganisms that pose an increasing threat to the country. These include the viruses causing Dengue, Ebola, Marburg and Zika, as well as the bacteria causing Anthrax and Plague. UKHSA believes that climate change. increasing drug resistance and, in some cases, the spread of mosquito vectors, make UK outbreaks more likely. Foreign pandemics could also cause the UK problems. Developing vaccines, tests and treatments now, could  greatly improve the current situation (https://www.theguardian.com/science/2025/mar/25/uk-experts-urge-prioritising-research-into-24-types-of-deadly-pathogen-families). The UKHSA list seems entirely logical. The difficulty, however, will be getting finance to develop vaccines, tests and treatments. Pharmaceutical companies tend to put their money into projects where there're predictable short-term profits. Governments also spend their limited available funds on current medical emergencies. We've never been good at preparing for possible future problems, even when the risks are growing.

Life On Mars?

 A mudstone sample was taken from Mars's Gale crater. This rock was billions of years old, from what may have been an old lake. A location with conditions for life. Mass spectrometry revealed the long-chain ketanes, decane, undecane and dodecane, in the rock. They have respectively 10, 11 and 12 carbons. Such molecules can be produced by abiotic (non-living ) processes. On Earth, however, they are generally breakdown products of fatty acid components of membranes around and within cells. On contact with water, these phospholipids (fats with a phosphate group) self-assemble into bilayers. These double membranes, control what goes into and what leaves cells (https://pubmed.ncbi.nlm.nih.gov/40127274/). These mudstone ketanes are longer than others found elsewhere on Mars. The evidence isn't, by any means, definitive but it suggests that, billions of years ago, there could have been life on Mars.
