The former head of the British financial services authority has suggested population decline and smaller families are good for the Climate; and?…

According to Lord Adair Turner, population decline should not be feared. It is certainly true that if the population of the UK were to shrink, so would our carbon emissions. Of course, this suggestion might have come with more authority if it had been made while he was still in post.

We have, in the last couple of centuries, unfortunately set up the financial world in such a way as to need a growing population. An increasing size of financial market in each country is required (according to current expertise) yet while there are some gains to be had in efficiency by each person, it is not possible for people to become more efficient endlessly. Furthermore, by this metric, a falling population would be a bad thing, as this would necessitate a shrinking market – even if it were shrinking slower than the population.

Has the Pandemic forced a new way of working on the BBC natural history unit?

In filming for the BBCs mating game, the film-makers for the BBC were forced to work in a different way to normal.

Given rules that were put in place to stop the epidemics spread, it was impossible in many instances to send film makers on trips all over the world. As a result, they were forced to rely on local wildlife film-makers.

The producers of the series, found that not only did this make it easier to get the footage required, but also meant that it was easier to know timings of when specific parts of the series would be complete.

Over the last couple of decades high definition cameras have become the norm and in recent years, local people around the world have been trained to use them. With the advance of 4G signal in wilder parts of the world, it is now possible to stay in touch with crews even when they are in the field. This also means that the carbon price of the production can fall dramatically.

The British government claims that 30% of of UK land is set aside for nature; what rubbish

At the current time 26% of the UK is designated as a national park, area of outstanding beauty or other form of protected area. However, to claim that this whole area is set aside for nature, is absurd. British national parks, unlike African ones still have human habitation within them.

Will Cop26 over shadow Kunming?

Cop26 is essential, there is no doubt, however there is a similarly important threat that the world is facing, and if we are not careful we wont start fighting it until it is too late.

What is Kunming there to fight? It is there to fight loss of biodiversity. Biodiversity is essential for the well running of ecosystems around the world which can often collapse without enough biodiversity.

Indeed, it is actually a problem that Kunming and Cop26 have been split. What we need is for the two fights to be fought side by side.

I have written in the past, about the problems for the Congo rainforest that have been caused by the local extinction of forest elephants. Without many of the wild animals that exist in these landscapes the forests and peat lands and grass lands will fail, releasing their huge carbon stocks back into the air.

These two must be tied together

Only 10% of the $17 trillion spent on Covid recovery went toward projects that would cut carbon emissions and restore nature

There is a constant complaint from vested interests, that the price of greening the world economy is just too high. Of course, when the world-wide economy needs a boost, these concerns go out of the window (until the emergency is over, then even these costs might be used to argue against saving the planet).

A tesla plane? what impact would this have

Elon Musk has talked about creating an electric plane, I think that this is a fantastic idea, but not from a tesla fanboy point of view.

Electric planes are in their infancy. There are a range of extremely light weight aircraft for learning to fly. There are also an increasing number of island hopper jets, which can allow easy access for small communities – at prices that are affordable, and therefore long-term as well as the far more environmentally friendly setup.

The other big move in this arena, is Ryanair. They are a budget airline operating throughout Europe, but they are building an aircraft which should be able to carry 186 people (31 rows of 6 seats) that would cover 80% of their routes. My hope is that this is a move into them behaving in a more compassionate way – they have a reputation of treating people poorly (I have experienced that first hand but that is another story)

Elon Musk envisaged a vertical take off and landing aircraft, and one which would fly high enough to travel at supersonic speeds. He did state that he thought batteries needed to reach 400wh/kg and the batteries that run tesla cars are currently 260wh/kg, so were still some way off. Having said that, tesla has some of the best battery research going on, and they are confident that the batteries will be ready in the next 3 or so years.

So what impact would a tesla plane have? Well what Musk is describing is largely a private jet, not a passenger jet. Never-the-less Tesla cars started and high cost and came down. It is likely that a Tesla plane would do something similar. Certainly, with the weight Tesla can bring to bare, it is likely that any involvement by Tesla would push the electrical aviation market place to new heights.

Could fusion arrive in time?

Fusions is the safe version of nuclear power, indeed it is what happens in the sun. Fision is much easier to get going – this is why it is able to operate in nuclear weapons.

We still aren’t at commercial point, but it suggests more and more clearly that this could power the human race in the future.

Fusion is the promise of limitless green energy in the near future. Cutting our electricity use, as well as making electricity in a greener way shouldnt stop, but it may arrive to help in the future.

Gains in the Virunga national park of the DRC are encouraging but threats continue

For the last 3 years there has been a significant baby boom in the forests of the Virungas. This is highly encouraging for the long term survival of the mountain gorillas that live here.

Unfortunately many threats remain. Parts of the park are potentially about to be reclassified for mining, and there are invading armed groups in various parts of the forest.

Currently, the DRC section of the park contains roughly 350 gorillas, though this number includes all mountain and lowland gorillas. However, the armed groups often make money by hunting wildlife both for bushmeat and the pet trade.

In recent years, Mountain gorillas have been moved from critically endangered, to the endangered list. However, this generally is in relation to the reduction of the population over the last few years. If the population reaches a small size, then reductions of any level are likely to wipe them out. This has not happened, thankfully, but given a population of only 350 animals, it is foolish to think that this wildlife population is out of danger, quite the contrary, it would take very little for this population to disappear – STILL and so we must not relax.

Current threats thought to exist for the park long term, do not worry about poaching, so much as land lost to oil and mineral extraction. Remember that an area can be deforested in a matter of a few weeks, it can take a century for the forest to return.
