While reading this post on LinkedIn my question did raise again! “It is one of those issues that deeply occupies my mind: the deforestation of the rainforest and its correlation with the shifting of the Intertropical Convergence Zone (ITCZ). This is a matter where the chaos theory of the famous butterfly effect, exemplified by the Morpho butterfly’s wing flapping, could […]
China was caught while digging up old vessels from WW2. They wanted tosalvage their low-background steel, also known as pre-war steel. This type of steel has low radiation and is valuable for use in medical and scientific equipment. Another possible reason is to obtain other metals such as aluminum and brass from the wrecks. Some of the vessels that have […]
Today we reached 8 000 000 000 people. Is le déluge imminent? On the day I was born, there were less than half of us as there are now. The minifigure, metaphor of my quest, allows me to imagine the unimaginable a little bit. Put 8 billion figures in a row and you have a line-up that goes around the […]
Soon it will be presidential elections in Brazil. The timing with geography education could not be better. Global deforestation and the disrupted carbon cycle thus become relevant again. So dear Jair, will you cut down more trees than before or will you still opt for a more sustainable way of making money? This old white man understands the dollar signs […]
We read it in almost every news report. Watercourses are very low.The economy is grinding to a halt because shipping is becoming difficult. Power plants are running out of cooling water. In this post I would like to talk about the parable of the little coliseum and the forest fire. You see my Spaceman standing on the edge my water […]
Today we “celebrate” #earthovershootday, the day on which we have used up all that the earth can produce. Not something to be really proud of, especially when you know that this date is coming earlier and earlier in the year.There is too little time in the geography course, but plenty of space to talk about the earth’s supporting capacity. It’s […]
The UN adjusted its forecast of the world’s population. It is not the forecast, but the better counting methods that adjusted the date. In fact, if you look at the proposed counters, you will notice the wide discrepancies in the estimates. The UN states that on Nov 15, 2022, we will officially have 8 000 000 000 inhabitants. This collage […]
On May 17, 2022, KATHO held a symposium on climate change and climate change. we The idea that half of the rise is due to the melting of the land glaciers and the other half to the expanding of the existing ocean water. This 50/50 split just didn’t taste right to me. It even made me curse! Show me the […]
One fact I always quote at the end of 4th grade: What if we were to build Australia, furnish it like the municipality of Dilbeek? A Flemish village with 1000 inhabitants per km² The earth has just over 7.7 billion inhabitants, Australia is 7.7 million km². A simple calculation shows that the population density of this vast country is about […]
The initial hype surrounding DiCaprio’s new movie has calmed down a bit. It was a nice momentum to surf along on, but to me it seems better to wait for the day when there will actually be 8 billion of us. Then I’ll do some work around preventing le déluge. Looking to the future with less somberness, is the message. […]
