A plan as a result of fear for rising sea levels

Some engineers consider that two dams should be built to protect millions of people in the Netherlands, Belgium, Scotland and England at a cost of 250 to 500 billion £. The proposal comes from the Netherlands because after having sold their gas, now the country fears part of it may disappear below the sea due to climate change. I think that taking climate change actions to prevent or at least slowdown climate change happens are probably much cheaper although less spectacular but at least the result will be clean air, ground and water. Further, huge pumps will be needed to remove the large volumes of water that rivers empty in what will eventually become a freshwater lake. Thus, the result will be a rising sea level of the ocean and a low freshwater sea so we only need to wait for the moment one or both dams break so a huge tsunami destroys the whole area. Not to mention the closing of what is now the busiest sea for transport over sea.

Maybe we should consider flooding old coal mines and gas fields with seawater. Is this possible or may the mine collapse? Is this wanted as the mine will be lost for future generations while it may contain undiscovered fossils yet? Maybe salt may crystallize out the water to become fresh groundwater? Or will it result in salty groundwater as it flows to surrounding groundwater reserves so first we need to remove the salt before pumping it in the underground?

Is the sea controllable?

But again, it shows the urgency to act to showdown climate change so we have time to slowly reduce the numbers of people in a natural way via birth control at a similar speed as the sea takes land.

Effects of climate change and rising sea levels become visible in Europe

Also lower areas in Europe start to feel the consequences of rising sea levels such as in Spain. And thus we may have to start to accept that these and other lower areas will disappear below the sea. Allow it to happen in a controlled way so people can be moved to other areas or changes to our architecture may allow people to stay in those areas while this may create new unique biodiverse areas.

In UK's towns and cities people complain that no flood defences are being built to protect against flooding; but what to do when too much rains falls in a very short time?

And as a sequel to my previous post, the article shows that pumps can stop working so I'm not sure that dams to keep the sea level of the North Sea low compared with the surrounding ocean are the solution (i.e., what if the dams may break? I fear a warning system will be too slow to warn everyone).

Realistic example to combat climate change

Instead of building dams in seas to try to stop that areas are flooded due to rising sea level, I believe more in taking actions that result in clean air, water and ground and thus benefit us all. One of them is to design modern houses and cities in harmony with the sea.

In Germany a project with a hydrogen train shows a clean economy is possible as it can even move a train, something I didn't expect to be possible yet. First, it can replace very polluting diesel trains but gradually, if successful, these trains may begin to replace trains powered via electric lines and thus these trains can result in more beautiful landscapes and cityscapes, unspoiled with electricity cables.

Steam trains are no longer acceptable as better and cleaner trains exist

It shows, believe that something is possible and people will try to make it work. But, don't believe something is possible and it can't happen. Of course, certain projects may not be the best. However, I believe a clean and sustainable economy is possible. Who else believes it is? Only the voices of the masses will be able to convince politicians that change is wanted.

(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...
