Tetraethyl lead, the scandal that never erupted
Modern history is full of stories of new chemicals sold on a large scale and afterwards causing problems. Sometimes, this causes a major upheaval. But by far the largest poisoning in history, that by tetraethyl lead, never ended in a scandal. It just faded away, even though oil and motor car companies neglected well-known dangers,
Bioenergy: fine, if from side streams
Why cannot we lift all barriers for the use of bioenergy? Because the energy sector is much larger than the food sector. The 20 billion tons of fossil fuels that mankind uses each year, is equivalent to 40 billion tons of biomass; whereas our yearly harvest for food is 9 billion tons, of which 3
Can we engineer life? 4.2 Plant gene technology: Bt aubergines
Anyone attached to Greece (and I am one of them) knows moussaka, one of the most traditional dishes of the Greek kitchen. I have mixed feelings on it, even though I love all ingredients of this oven dish with aubergines as main ingredient. How come? Many Greek chefs add cinnamon to the dish, in addition
Séralini disproven – what will the EU do now?
Anyone who opposes genetically modified (GM) food can tell you that ‘in France’ they found that GM maize causes cancer in rats. This study was conducted under leadership of Gilles-Éric Séralini, professor in molecular biology at the University of Caen. His results, published in 2012, caused an upheaval. They stopped short the very gradual change
Earth Overshoot Day, or the power of doomsday messages
This year, August 1 is Earth Overshoot Day. Each year, this is the day at which mankind has used up its stock of biological resources for that year. Never has this Day been so early in the year, meaning that we have never depleted the Earth’s resources so fast. But it would be fairer to
Geopolitics of information, the next conflict zone
In four earlier articles we came to the conclusion that geopolitics of fossil, mineral and agricultural resources will become less important. But a new geopolitical dimension quickly rises to the forefront: geopolitics of information. Information becomes less reliable. People create their own worlds with social media, which leaves less and less space for generally shared
Young farmers and the lack of large-scale agricultural innovation projects
Last week I visited a network meeting focusing on rural development. This focus area lies at a somewhat greater distance from direct bio-based developments, but nevertheless will be impacted by the bio-based economy. One of the participants mentioned the lack of larger scale agricultural innovation projects. The reason I attended this meeting was that I
Cloning monkeys: slippery slope or dead end?
Last January, the news that a Chinese team of scientists had cloned macaque monkeys drew a lot of attention. Discussion was quick – too quick – to focus on the question if cloning monkeys could lead to cloning humans. But the real question might be: what is the goal of this research? And are there
