Species watch

I am intending to make this into a new set of articles that will appear on this website. Obviously, these species will not be the only ones that are covered – for those who read this website regularly, you will know that I talk about a wide range of species.

The species that I am going to look at are those which often attract visitors to see just them. With the majority of the species we will follow they are found across a surprisingly large number of countries – some however are as interesting but are found in only one country. In each instance we will look at an entire group of species that look similar. However, due to the differences in these many different countries, these species can be thriving in one country and threatened with local extinction in another. As a result it is important to give this more focus.

These articles will be marked by SW

Those species that I will initially focus on include:

Visit to local zoo, one that I know very well – Marwell zoo

If you live in the UK, there is relatively little wildlife to watch (when compared to somewhere like South Africa), which is why zoos are often such popular places.

 

An Amur tiger on the prowl

As people have come to have better thoughts about keeping animals in zoos, these places have greatly improved. Long gone is enclosures such as “bear pits”. Now zoos give the animal relatively large enclosures with (as much as possible) plants and other items that make the area similar to the animals wild habitat. Also a great deal of progress has been made in understanding the various conditions that are required in order to make the animals happy enough to breed.

I have, in the past, been a wildlife educator at the zoo. This has consisted of me visiting the zoo a few times each month, and spending a few hours beside specific animals. I am there to engage visitors – in some cases help them see the animal, as well as talking about its wild habitat and the threats that the animal faces to its ongoing survival. Due to covid, this has been impossible in the last few years.

 

Marwell zoo has been particularly good on its big cats. Unfortunately since our last visit, they have lost their Amur leopards and their cheetah – however, as with both of these, the animals were old, and the zoo is perfectly set up for breeding of these species, therefore if new cheetah or Amur leopards arrive this can continue. One of the main ways that these zoos can work in this way, is to have two enclosures next to each other, this allows the connecting gate to be opened or closed depending on circumstances, allowing male and female to spend times apart and together – as close to mirroring how they would behave in the wild as possible.

 

The Amur leopard is a stunning animal and with its wild population being so threatened (a superb decade has allowed the population to grow back above 100 (WWF estimates that there are now about 100 wild adult Amur leopards) from a population of as few as 20 adults at the turn of the century. As such breeding is essential, and I hope that in the long run, the zoo can have similar success with another pair. Cheetah, while less endangered overall (though the Saharan cheetah and the Iranian cheetah are both this endangered) is famously hard to breed, so we can only hope that in the future cheetah will once again live in this place.

 

When visiting a zoo, I like to go on a very quiet day, as the animals tend to behave more naturally so I like to go outside weekends. However with children that is not currently possible due to school. Nevertheless we had a lovely day, and despite the missing wildlife saw many lovely things.

 

Whether you believe that animals should ever be caged or not, it should be clear to everyone that at the current time, without zoos many species might well be lost from the world. It is also true that many zoos do essential work in the wild to conserve remaining wilderness.

Looking at the capability of the world being powered from solar or wind

The sun sends 470 exajoules of energy to the earth every 88 minutes. This is how much energy the earth uses each year. If we captured just 1% of the sun’s energy this would still give a 6 times more electricity than we need. 

In a similar vein, if wind turbines collected just 20% of the wind energy on earth this would be 8 times what the entire world uses each year.

In terms of area, to generate all the power that the earth needs (using current efficiency) we would need roughly 1 million square km or about 11% of the Sahara desert. Obviously, this is an oversimplification, but it shows that the world is more than capable of running on clean energy.

The energy is there to be used, we just need to undertake it at speed. Vested interests in fossil fuel companies have fought aggressively against this move for decades. Their time must be over, the world can and must clean up its act.

Bwindi impenetrable forest threatened by road plans

Ugandan authorities are considering two roads that will pass through Bwindi. These roads are likely to have two devastating impacts.

Currently this forest consists of unbroken forest – but will it?

Firstly, these roads are likely to splinter the park from the connected park across the border in the DCR. As with the proposed Serengeti road, neither side of the road is big enough for large ecosystems to survive long term, therefore you are threatening one of the biggest draws of tourists to the country – these tourists if well managed bring the means to pull millions out of poverty.

If these roads go ahead, then much damage will be done. Of greatest concern is a road that would run north to south in the far west of park, cutting the park off from its sister reserves across the border in the DRC. This could well lead the the rapid loss of the mountain gorilla population

The other problem is that roads ease the progress of poachers deep into the park. It has regularly been shown that a road is often the easiest way to remove the wildlife that lives in an area.

Tesla has made more sales than Audi BMW and Mercedes combined in their home market

In September Tesla sold more cars in Germany than Audi A4 BMW 3 series and Mercedes c class combined.

Why is this important? Well firstly the Tesla cars are more expensive. As a result they naturally compete against similarly priced cars with a combustion engine. This is why this news is so exciting – it is clearly taking an enormous part of this well established market.

What is particularly concerning, is that these are the people which car companies make their most profit from. Those people with less money, will tend to either buy used cars – no extra money for the established players (though with supercharging and various other things like data, Tesla can profit), or buy small runabout cars – these tend her very small profit margins, and anyway even if you managed to make 20% profit when you’re only talking about to the car that costs £5,000, you still have to sell an awful lot of them to make substantial rewards.

Indeed the next few years are perhaps their last chance to fight back. This is because with the Tesla gigafactory in Berlin, the number of cheaper Tesla cars will explode in the next few years. 5 to 10 years after this many of those will join the used car market at prices that could quickly reduce cheaper cars demand as well.

Where are we (my family and I)? We have been liking the idea of going electric for some time. Unfortunately someone wrote our car a few years ago – too soon for us to go electric. However (as I wrote about a few weeks ago), we have just jumped in having found an old tesla s for far less than normal in the UK. Indeed with the current price of petrol, we think that it will only be about 7 years before we save the purchase price in reduced cost of travel

Saving the Persian leopard

Leopards once roamed through Africa and Asia and even up into parts of Europe. Now their range is diminished and many of the subspecies are either endangered or critically so.

The Persian Leopard (also referred to as the Anatolian leopard and the Cascina Leopard)  Iranian Plateau and surrounding areas encompassing Turkey, the Caucasus (Armenia Azerbaijan and other parts of southern Russia), Iran, Israel, Turkmenistan, Afghanistan and possibly Pakistan.

These ancient Iraqi forests are under threat, and with it the last stronghold of the Persian Leopard

Today it is thought that the population only consists of 1000 adults, though their population is highly fragmented. One of its strongholds is the Iraqi Kurdistan forests, unfortunately as much as half of these forests has been lost to illegal deforestation.

Unfortunately if the Persian Leopard cannot hang on here there is little hope elsewhere. Numbers have roughly halved (as habitat has similarly halved).

Tigers are still moving between reserves, we must make it easier

Tigers once numbered 100,000 in India. My great great grandfather spent time in India, and I grew up hearing my great grandmother talking about the time that she went with her father on her pet elephant (as you do) to find a tiger that had been maimed during a failed hunt. This was essential, as a maimed tiger (or indeed lion leopard or jaguar) is of great danger to those living nearby. A maimed tiger cannot hunt as it normally would, and humans are far easier prey.

We have never learnt to live alongside tigers. As a result, as the human population has grown, the tiger population has been squashed into less and less land. If a healthy population can survive for the next century the human population may fall again and allow the tiger to thrive once more

These days the situation is very different. Currently there is a little over 3000 tigers living in the wilds of India, a number that has doubled in a surprisingly short period of time.

When was human caused climate change first noticed?

There are still a large number of people with vested interests, who are arguing that climate change science is not settled and we need to wait a bit more.

How long should we wait?

Guy Callendar released a paper in 1938 – considered revolutionary at the time, which linked fossil fuel burning to the warming of the earths atmosphere. Indeed in 1896 Svante Arrhenius a Swedish scientist first predicted that increasing carbon emissions could significantly increase surface temperatures.

In other words it is now 126 years since a scientist predicted that global warming would be likely if we continued to release carbon emissions, and a paper was released 84 years ago confirming that Scvante Arrhenius prediction was correct.

So why are we still arguing about it? Does the free market truly allow profit to be prioritised over a scientific fact that was proposed more than a century ago, and confirmed nearly a century ago? Had the world dealt with carbon emissions back then we would be looking at a very different situation.

We have bought a used electric car: does it make financial sense? Why should you consider doing the same.

So we have recently bought an electric car!

This is what a tesla looks like

For any regular readers, you would have seen my article from a few days ago. When people are writing articles comparing the emissions from generating electricity to the tailpipe emissions of the combustion engine – any one with a brain is asking why? Given you are not comparing like for like. We estimate that our carbon emissions reductions from replacing our car may reach 10 tonnes a year. Each fill up of our petrol car meant about 40kg of petrol, which took 110kg of emissions to dig it out of the ground and transport it (often around the world).

So from an environmental position, yes it certainly makes sense.

But what about from a financial position?

Fossil fuel cars make ‘hundreds of times’ more waste than electric cars – according to a Guardian article, despite what most media tries to claim

This should not be news to people, but because of the rubbish that is spread by many with vested interests in the current situation, it needs to be dealt with again.

So the argument is that because electric cars battery does not last forever, but every part of the combustion engine car does, the electric car is going to make more waste.
