Paignton zoo in Devon has a baby Dik-Dik

The dik-dik is a small antelope, found in East Africa. I have been lucky enough to encounter them on many occasions, when on safari in Kenya.

They tend to move around in pairs, and the bond is so strong, it is not uncommon for them to follow each other out in front of cars.

A Kirk’s dik-dik in the wild

With a population of almost 1 million, this species is listed as least concern, never-the-less it is of great interest to see it in captivity.

Paignton zoo had a baby dik-dik arrive on new years day, so it will be even smaller than normal.

Is the USA beef market destined to crash?

Looking at who is eating the majority of beef in the USA is alarming for the future of the industry. This is because older generations are eating the vast majority. Beef was at its strongest in the 1970s, with the average amount of beef eaten per person in 1975 being around 90 pounds or 40kg, but having dropped to just 57 pounds or 25kg.

Chicken is now the USA most consumed meat.

While this might be bad for the beef industry, it is good for the climate. Beef produces around 10 times the greenhouse gases that poultry does, and 20-60 times the amount that is released getting the same nutrition from plants.

According to this study, just 12% of people were responsible for eating half of the beef consumed in the country.

Transforming coal into protein for livestock feed uses 0.1% of the space!

Currently, land given over to growing animal feed accounts for 40 million square kg (15.4 million square miles). Given the worlds land mass accounts for almost 60 million square miles (160 million square km( this is a significant increase). This amount of land, freed up, could potentially allow a huge improvement in the amount of space given over to wilderness on the earth.

So where would we get protein for livestock feed?

Chinese scientists have created a method which allows the conversion of coal into protein – far more effectively than with plants. 0.1% of this land is required in this new system. It is true that this still accounts for 60,000 square miles,

So the process has a number of steps.

  1. The coal is transfored into methanol via gasification (this can now be done with a near zero carbon emissions)
  2. The methane is then fed to a special strain of Pichia pastoris yeast, which ferments the methanol, in order to produce a single-cell protein complete with a range of amino acids, vitamins, inorganic salts, fats and carbohydrates. There is far more protein in this than in plants and it can be used to partially replace the protein currently used

The conversion efficiency is at a remarkable 92%. This means that it is a cost effective replacement. Now, how much of the protein can be replaced, however a trial facility has already produced thousands of tonnes of this protein.

So if we assume that it cannot replace all of the protein, it seems reasonable to be able to replace 50% or 80% of the protein.

Even countries like the USA could free up thousands of square miles.

The idea that we could free up 30 -48 millions square kilometres (7.5 to 12 million square miles) to be returned to wilderness and carbon sinks among other purposes. If just half of this land was rewilded, it would allow large amounts of the land around the world to return to a wild state, which would help us cut emissions.

Now, it is true that this coal will be emitted as carbon at the end of the line, but if enough of the freed land is used for forest and similar, the net carbon gain can be huge.

More than 20 indigenous groups have called on the Australian government to stop culling Dingoes

For indigenous communities, killing dingoes are a cultural icon, and for them killing them is tantamount to killing a family member.

This has been raised more forcefully, after recent surveys showed that the Australian dingo is actually genetically very pure.

Given their classification of being native species, they should not be culled.

It is true that there is some question as to when the dingo arrived in Australia, and whether it arrived with early humans, however that would still mean that they arrived 50,000 years ago, which would definitely make them native in almost any regular description.

Swearing parrots

Obviously not the first place in the world to have this problem, but Lincolnshire wildlife park has 8 grey parrots and they have started swearing.

The zoo has in the past, isolated the bird, in the hopes of this behaviour not spreading. Now they are trying a different tack, by putting the rude birds in with many more, in the hopes that these birds will learn some more polite words from the rest of the bird flock

This video shows them using a swear word almost instantly.

As you can see, the parrot will mimic any language, and so this is not the first time, and wont be the last.

Can simple changes help the Javan rhino recover?

Above is a fascinating video about a photographers journey to try to see this rhinos in the wild (spoiler alert, it was a success, as you can see from the thumbnail). The problem is that despite this video being from 8 years ago, the Javan rhino has not recovered a great deal in the intervening years.

So, when I say it has not recovered much in those years, what do I mean? Well in 2015 the Javan rhino population was estimated at 72, it is now thought to number 76.

A new study has suggested a number of idaes that might accelerate the recovery of this rhino.

These are captive breeding, and forest clearance to give more areas for the rhino to feed.

While the latter may well have some merit, the former may not. It should also be noted that currently 13 of the rhino show signs of inbreeding. So why not bring some of the remaining rhino into captivity, in order to breed? This has not proved highly successful in the past, and indeed often a number of individuals die in the early stages. With a population of just 76 individuals, we do not have spare rhino to gamble with.

Like the Sumatran rhino, the small population left in Java is a relict of a species which roamed a great area of Asia, until not that long ago. If we can save this Javan population there is a potential in the future to reintroduce them to a wide variety of countries in this part of Asia, both mainland and islands.

Will this happen? who knows

Is the Javan tiger extinct? Update on image

This is a post origially put out 2 years ago, however, I found the video had not worked, so here it is again.

There are still sizable areas of protected land in Java, and in 2017 a warden took the below photo.

 

 

Now it is hard to see it clearly, but to me I think it looks more like a leopard unfortunately

Now I am unsure about this picture but would be pleasantly pleased to be proved wrong.

If not, the Javan tiger is very similar to the Sumatran tiger. As such, with a recovery in the wild Sumatran population if a reserve is not suffering poaching, it would be possible to bring the tiger back to Java.

There has been no more sightings of this animal, which suggests that this sighting cannot have been real, but who knows.

It should be noted, that while rangers decided that it must be showing a leopard, this is still exciting. This is because, while a leopard is not a species declared extinct 48 years ago, the Javan Leopard is a species that is highly threatened. The current estimate of the population of this leopard species is between 188-571, most likely around 250 leopards is an accurate figure.

The video below is a clip filmed of the Javan leopard

Chinese water deer, while vanishing at home, are thriving in the UK

Certainly not native, but doing well

There are perhaps only 10,000 of this species in China, though there are around 700,000 living across the border in South Korea (slightly different subspecies).

They are also doing well in the UK with around 2000 living in the country, having been introduced by the Duke of Bedford into his animal collection, and then quickly escaped (around 100 years ago)

This makes the UK an important part of this species survival. It is particularly easy to see in the Norfolk broads, but is also found in other counties in this area.

Electric two wheelers are cutting carbon emissions by 1 million barrels of oil a day

There are a variety of different industries which need to stop using carbon. The hardest, is transport. While electrifying aircraft is incredibly hard, we have already worked out everything we need to electrify the worlds roads.

An electric scooter uses around 1/10 of the electricity of an efficient small electric car, so every person who switches from car to e-scooter will save a lot of energy each year.

Worldwide, it has been calculated, that at the current time, e-scooters are cutting carbon emissions 4 times faster than electric cars.

This makes it clear, that we need to electrify all forms of transport.
