Animal conservation

Everywhere in the worlds animals are on the brink of extinction. Indeed, animals in the wild killed for ivory while lions and giraffes are not even safe in zoos. And when animal numbers recover, humans complain and say we need to kill them. I've warned before against blaming animals for the destruction of the environment and climate change or we start to reduce their numbers - now your own species. And thus now there is a discussion about whether deer need to be killed and more specifically about the numbers of animals that should be killed. But did they study other ways? Here some suggestions:


Deer in Richmond Park, located in the middle of London, UK

  • Maybe relocate them to other parts of Europe where they went (almost) extinct?
  • Maybe reintroduce wolfs. Of course, not large numbers but sufficient so they can hunt the deer without being a treat to humans.
  • Maybe castrate a number of male deer so they can live without multiplying.
  • Maybe replant trees in enclosures the deer can't enter so they can't damaged the young trees?

As long as Europe can't manage larger numbers of animals than it should not lecture developing countries to keep their more often much more dangerous animals.


Example how biodiversity control animal numbers in a natural way

An article that shows how biodiversity can help to control a population. Higher I wrote how the introduction of wolfs in Scotland may help to control the deer population. Here an example how it may work.

Although grey squirrels are playful animals, many in the UK hates them because they drove away they red squirrels while now they are too numerous. And thus they may be shot at a high cost for taxpayers; as hunting is forbidden, other ways are needed to allow the killing of animals.



But, it seems where pine martens live few if any grey squirrels remain while the red squirrel populations recover. Indeed, as the red ones are lighter, they can escape pine martens via the smallest branches of trees while the heavier grey squirrel can't so the grey ones move away from territory where pine martens hunt.

The article also mentions:
"... grey squirrels in the region haunted by pine martens are much thinner than those elsewhere...".
Thus, may a smaller version of grey squirrels rise to live together with red squirrels so pine martens can hunt both and balance their populations?

With predators, potential prey such as squirrels for pine martens has less time to spend time breeding while young animals are easier prey and thus fewer become adult. And thus a natural reduction of what are considered "pests" until a new healthy balance is reached.

I wonder if the pine martens has been allowed to do the job of reducing numbers of grey squirrels or did hunters win so they can kill? Still, bringing unbalance is not good for the environment. And thus, what will be the result of the current major cull of badgers? Which animals will become the next "pest"?

(18l) Belgium, king Leopold II and Congo

Image
Leopold II in Congo Belgium has a terrible human rights track record because of its second king Leopold II (1835 - 1909) during whose reign millions of people in Congo died. People may say he is not personally responsible but the same can be said of Hitler. However, Leopold II could have ruled only Belgium but this he considered too small and thus he lobbied to gain Congo for himself and succeeded on the condition he would treat its people correct, something he refused to do from day one. Therefore, he is responsible as he actively searched for this expansion to enrich himself so he could enlarge his own glory in his kingdom Belgium with neglect of his "subjects" in Congo. And people in those days had already a conscience because the king had to replace the first ambassador who refused to collaborate to expand the king's personal property.   To have an impression of the terror Leopold ii allowed in Congo is a picture in this article that shows a black father who l...

(05d) PM Merkel is against Eurobonds - I agree to some extend

I'm having again Internet after almost a three months break. Finally, back to the world. Many European politicians (and certainly economists) want to introduce Eurobonds and as I understand it, the EU may take some (most, all?) of the debts of poorer European countries and spread it over Europe so that both strong and weak shoulders will carry the problems. Of course, it is only understandable that Europe wants to help countries that are in need (as it should do because they are members). But, as the German PM Angela Merkel (a woman who thinks differently than most men and wants other solutions then the usual ones), I am against spreading debts because it will weaken every country that take some of the debts (it is similar to banks using savings of people to pay off their debts so that when people want their money the banks can't give it anymore (I wonder whether rating agencies threat some countries well so those countries are prepared to take responsibilities to save count...

Buildup of Tensions in Societies Throughout the World

Image
We notice worldwide tensions are growing within societies. This is mainly as a result of growing inequality but also other factors are involved such as a virus and climate change that destroys crops so people start to migrate as essentials become rarer and thus more expensive compared with what people earn. The result is likely that increasingly people in places where the migrants move to will demand a closing of their borders. Let's discuss. Financial crisis 2008-2009 While inequality was growing as a result of what many people earned versus rising costs of products, this accelerated when the financial crisis was organised just over ten years ago. As a result, people lost work and many even their home such as in the USA so poverty increased although the rich became richer. But, while house prices dropped because many flats and houses became available, those with money were able to buy them cheaper and sell or rent them out to make money when property prices rose again. The problem...
