Wild boar continue to spread across the UK, arrive just a mile from where i live (Still sorting issues, but progressing)

I have missed writing regularly, but have been having some issues with this website. I am hoping that in the near future these will be resolved, and allow the website to reach some of its potential – however for now, back to this article.

The UK is recognized as one of the most nature depleted places on earth. never the less, there is wildlife in the shadow of humans. A very wide range of wildlife has been lost, as humans have not left the space – this is causing us issues, not least because there are no apex predators left.

Wild boar, however, were accidently released – they were bred for meat, and between a variety of escapes and intentional released populations, a wild population has been established in the UK. Domestic pigs are descended from wild boar – it is thouoght that they were domesticated twice, once in the near middle east around 8500 years ago, and again in China around 6500 years ago (though it should be noted that these dates are still pretty unclear. 8500 years is not a long time in genetic evolution, and as such they are still capable to interbreed, even though there is a significant difference in how these two groups live.

There is an estimated 2600 wild boar living in the UK. The largest populations are listed below, though it does not account for all of them

  • Forest of Dean: This area has the most established and largest wild boar population in the UK. The population is estimated to be around 1,200 animals.
  • Kent/East Sussex: This area has a population of 250-300 wild boar.
  • West Dorset: This population is estimated to be over 50 animals.
  • North Devon: This area has a smaller population, estimated to be between 50 and 100 wild boar.

Wild boar are incredibly important for the health of forests – wild boar turn soil in their search for roots and tubers, and this is perfect for the growth of new seedlings. Boar rootling areas are often full of tree saplings and shoots growing together. It is something that has been missed for a very long time, and the health of forests that the boar returns to is greatly improving.

The area that I live in, has a great deal of army land, and therefore, I believe that the area could support hundreds of boar, if not more.

This individual boar, is likely to be a young roaming male, and usually, the first visitor does not settle within an area, however, females also roam, and should a male and female meet, they are likely to become a breeding pair, and at that point the population can grow fast as a breeding pair (when they have some domestic pig genes in them) potentially having 3 litters of 10 or more a year.

Will a breeding population be established around here? It is still for the time being, chance, however at this breeding rate, it is quite conceivable for boar to be back across the UK within the next couple of decades. Pure wild boar would be better, however adaption back to living in the wild will likely slow their breeding rate relatively fast.

Oil, Gas and coal roundup ( more in future)

While these fuels power much of the creation of electricity around the world, as well as most transport and heating, they all need to either be left in the ground or 100% of their emissions. Below is a roundup of a group of articles of importance on these subjects.

Norway has released an engine that runs on hydrogen – does this end electric cars future?

Unfortunately, this is an article that does not need much work. Unless we find an insane quantity of hydrogen buried under the ground somewhere (and it would have to be infinite to really count), the question is, how much electricity does it take to make 1kg of hydrogen and how far can the car drive on it? If this is more than an electric car, then perhaps Norway has a point.

Black rhino calf born in Kenya

The eastern black rhino is incredibly endangered, with just 1000 spread across a huge area. In this region, just 8 are known to live, so to see young is incredibly rare.

Rhino horn is incredibly valuable on the far East traditional medicine market, despite the fact that multiple scientific studies have shown that the rhino horn does nothing for humans. Never-the-less, this unmet demand for rhino horn, linked with the huge explosion of wealth in places like China, means that rhino horn is incredible valuable. While eastern black rhino horns rarely weigh more than 3kg, this can still be worth $200,000, which is very tempting, in a country where the average salary is under $200 a month.

As living conditions increase in the area, the desire to poach these animals is likely to decrease. Of course, these rhino are also likely to be worth similar amounts in tourism dollars across their lifetime, but that is a long-term thing, and something that the whole area benefits from (rather than the poacher, who is often struggling to make ends meet – though middlemen are instead making a fortune).

The livestock lobby is fighting against lab-grown meat this is why we must not let them win

Livestock takes up roughly 20% of the worlds land, or around 50% of the worlds agricultural land. Astoundingly, around 1.3 billion people around the world are involved in the livestock industry.

The worlds remaining land wilderness, takes up just 25% of the worlds land – should we move toa system of growing meat in labs, we could almost double the amount of space for wildlife, which would allow many of the worlds endangered species to recover.

Apart form saving so much of the worlds wilderness, and wildlife, why should we do this? Well, firstly, the fact that people want things to stay as they are, is not new. Every new invention has lead to a change in the lives of many people – before farming came into existence, all the healthy men of each village (and in places, many of the healthy women) would have spent the majority of their time hunting. Looking at the natural world, animals like lion and leopard split their time between hunting and resting, with little else (apart from reproduction) being thought of.

As electric cars started to appear, the vast majority of car companies tried to stop their progress. Indeed, many spent their time buying inventions and smaller companies, just to kill their electric car program. This was not because they were intrinsically afraid of the electric car, but because they were afraid that if adopted, they might have a smaller market share than they did with the internal combustion engine car. As tends to happen in this situation, however, many of these companies are thought likely to go out of business in the next 2 decades (and it took a start-up, Tesla to fully make electric cars work – even now, many are still trying to go back). The same can be said for the factory production line, and many many others.

The problem is that livestock farming is only second to the fossil fuel industry, in terms of its contribution to climate change, so if humanity is to survive, it needs to change dramatically.

Why should we be worried about saving the worlds wildernesses? I think that a great deal of the population feels that we should save them for their own intrinsic value, but there is more than that. Rainforests around the world are the engine that supplies much of these areas rain, and without the rainforest often the area will collapse into desert.

Some suggest that we should all go to a plant-based diet, and certainly this would do what we want (though it should be noted, that this leaves the livestock industry in the same place – indeed, the livestock industry as it currently is, must have its days numbered, as humanity cannot afford its carbon footprint or it will continue our descent into climate breakdown). The only alternative to this is to produce the dairy and meat through other means; and these means are multiplying around the world, as it is recognized that there is a lot of money available for those who solve it early.

These range from growing meat on a scaffold from cells taken from a live animal. This idea is rapidly growing in popularity, though some think that this is a dead end, and instead a lot of people are looking at brewing microbes, which can be made to have a taste and texture that will make them indistinguishable from the real thing. This would also allow the unhealthy parts like fat to be not grown. It avoids the need for a lot of land, needs no fertilizer and greatly reduces the amount of fresh water needed (some can use salt water).

Protectionism is not restricted to farmers, with many governments getting in on the act, and in the EU a new group is pushing for a continent wide ban.

I think that these things will be developed somewhere, and we will miss out, if this happens in places like China (they have a great incentive, as their population eats little real meat, but as the wealth of people are increasing, they are demanding to eat a diet more like the west. For most of us, we are going to be watching from the sidelines, in terms of what happens next, but we can write to our representatives, and make sure that livestock owners are not the only voices that they hear.

Is Asia’s plummeting fertility rate a going to lead to a crisis, or might it help save the planet?

A large crowd

Of the slightly over 8 billion humans on earth, 4.641 billion, or just under 60% live in Asia. While this is expected to grow to 5.25 billion people in 2055 it will only be 54% (due to increasing populations elsewhere in the world) of global population at the time.

So, what is the problem? An average fertility rate of 2.1 is currently considered necessary to maintain population levels (that is, 2.1 births per female). When the fertility rate drops below this rate, there are not enough babies being born to replace all of the people dying. As environmentalists, this is good, as the human population is thought (by some) to be too high to sustainable retain long-term (estimates as to what population the earth can sustain long-term range from a relatively small 0.65 billion to an enormous 9-10 billion). Of course, it depends on what we consider as sustainable survival – for me, and I hope for most of you, what I would consider sustainable, would be a low enough population to allow all other species on earth to thrive, so I would suggest that a number near the bottom of this list is more reasonable.

Below, we will look at a range of Asian countries with large populations

Scientists think they know what wiped out the largest ever ape (a huge species of Orangutan)

Gigantopithecus blacki – the likely largest species of great ape ever to have existed

Thought to have gone extinct 295,000 and 215,000 years ago, having first appeared around 2 million years ago. Rather than being caused by our ancestors, it unfortunately became extinct as a result of the climate became more seasonal and the plant-eating primate struggled to adapt to changing vegetation.

Might this be a for-shadow for the extinction of the rest of the great apes?

The largest ever primate Gigantopithecus blacki went extinct at a time when Asian great apes were thriving, and its demise has long been a considered a mystery. A massive regional study of 22 caves in southern China explores a species on the brink of extinction between 295,000 and 215,000 years ago. As the environment became more seasonal, forest plant communities changed Primates such as orangutans adapted their eating habits and behaviors in response but G. blacki showed signs of stress, struggled to adapt and their numbers dwindled.

This species was 3m (10 feet) tall, it was around twice the weight of the the largest gorillas. It was first identified around 100 years ago, from fossilized teeth (around 2000 have been found) sold as dragon bones. Around (700,000 or) 600,000 years ago we start to see large environmental changes and during that period we see a decline in the availability of fruit.

As a result Giganto (ate) less nutritious fall-back foods. We’ve got evidence from looking at the teeth structure, Westaway added. Pits and scratches on the teeth suggest it was eating really fibrous food such as bark and twigs from the forest floor.

Funnily enough, they are not thought to have ever lived in caves, but instead had their remains carried there.

As there are no, non-cranial fossils (i.e. any fossils of any part of this species below the neck) , it’s hard to know exactly what Gigantopithecus would have looked like. Its upper molars are 57.8% larger than a gorilla’s and the lower molars are 33% larger, suggesting its body weight would have been 200 to 300 kilograms.

Given its size, it is thought to have long abandoned the tree-tops, though given its closest living relative is the Bornean Orangutan, of which, older males are often spending more time on the ground given their large weight as well.

There are fossils of homo erectus from nearby, from around 800,000 years ago, suggesting that we might well have lived alongside them. How happy or harmonious this relationship is, we cannot know. Unfortunately, given recent history, it is quite likely that directly or indirectly we had a hand in this species extinction, given our impact on almost all other species that we know.

Platinum Rhino, the worlds largest captive rhino breeding operation sold to africaparksnetwork! (update, instagram embed did not work)

Hearing this news, one might think “great, another 10-20 rhino”? Think again.

Platinum rhino holds as much as 15% of the current wild population in its operation -2000 individuals. Here is an instagram on the news!

This could be great! Current rhino numbers are estimated to be in the low 2000, down 79% since 2011. Releasing the whole herd back into the Kruger could allow numbers a sizable boost, and rapidly move the kruger back towards its former stronghold of the white rhino. However, in the first half of 2023 over 200 rhino were poached from the Kruger, suggesting that this is not going to be easy.

Unfortunately, the Kruger is already one of the best preserved large reserves in the world. Thankfully, rhino horn has dropped in value from its peak in 2012 of $65,000 per kg, down to a current $8000 per kg. It would be good to depress this further, however the risks for the poacher are very high: not only are many poachers killed by the rhino, they are also often killed by other wildlife such as lions – and the Kruger has a sizable number of man-eating specialists.

I suspect the organization will spread the rhino around, across many of their reserves. Hopefully the recognition that farms like this make no sense, will allow them to thrive back in the wild.

Education is still needed in China, Vietnam and elsewhere. Rhino horn is the same substance as your finger-nails, Keratin. Consuming it will make no difference to any medical condition, science has tried to show any positive health benefit, and can see nothing scientific – at best a placebo effect.

Below, is a video about this farm, 6 years ago back in its heyday. Hopefully, all these rhino can recover white rhino populations far and wide.

Albino panda spotted in the wild

Rare albino panda seen again

If anyone has been reading this blog for some time, you may remember me writing about an albino panda that was photographed in wulong nature reserve in China (click here to read it)

This bear has been caught on camera (see above) and appears to be doing well. It has started to display mating behaviour and appears to be extremely healthy. It has all the features generally associated with albinism, with white fur and red eyes.. It is now around 5-6 years old, and has been seen playing with other pandas, suggesting that its unusual colouring is not leading to it being shunned from other pandas.

It was filmed approaching a mother with a 2 year-old cub. As the mother was ready to mate again, and yet did not show aggression to this male bear getting close, it is likely that this female is the mother of the white cub.

Currently thought to be numbered 1800 in the wild, the panda is currently listed as threatened – having been delisted from being endangered in 2016. It is also an integral part of the Giant panda national park which is being created, and links 67 panda reserves, allowing the bears to travel between the former islands of habitat, giving them the ability to breed in a more natural way. This is important, as inbreeding would make panda conservation even harder.

Panda bear behaving like a meat eater/scavenger?

This bear was filmed, gnawing on a bone from a takin, a species of wild cattle.

For a species which is thought to survive exclusively on bamboo, this would be strange behaviour.

However, pandas do not survive exclusively on bamboo as roughly 1% of their diet comes from other foods. In fact, their digestive system is typical of a carnivore, so the remaining 1% of their diet can include eggs, small animals and carrion – like this bone. Pandas are also known to forage in farmland for pumpkin, kidney beans, wheat and domestic pig food.

The thing is, pandas eat up to 38kg a day, which means that during the week, they eat around 3kg of food that is not bamboo. This is significant, and while much of this may well be other vegetation, if the time spent on other food sources was around 1% of the time, it would suggest at least 1 hour a week spent eating other things.

One must remember that their intelligence is on a par with Chimpanzee and gorilla -like other bears, so they are capable of working things out.
