Nature can be approached without competence. Emotional attachment is fine. If we delve deeper into the issue, we realize that a lot of processes that have evolved over years or even centuries are hard to study. The learning about nature is manifold and many scientific disciplines deal with nature in the broad sense of the word.
Today the study of nature is scattered across so many disciplines that an overall view of the field seems hard to achieve. This creates a problem to teach a competence to deal with topics around nature. Water, air, species, soil, climate or reproduction are all topics in which we have to make far-reaching individual and collective choices. This requires adequate competences to allow judgments about opportunities and risks involved.
For more than 100 years now we have researched education systems and processes, but the competences to talk and explain basic processes in nature are still scarce. Classification systems are a static way to sort nature into categories. Processes of evolution and development have more or less human input.
We all gain if we keep an eye on education and learning processes that have been applied years ago. The field of the history of education provides clues about some forgotten approaches. Learning about nature and how to acquire competence in the field has been an issue in this field for at least 100 years. It is time to test some of these approaches again to see what went wrong in learning about nature. Man-made climate change is only at the end of a causal chain of things and people moving in the wrong direction. We probably have to press the reset button and start from scratch with the learning and the tracing of wrong decisions. Maybe, the start is the appreciation of a splendid bouquet of flowers.

Competence Gardening
Primary Schools in Berlin have the possibility to participate in the “Gartenarbeitsschule”, the school with learning goal of gardening. It is an interesting option to go out into the real world and deal with nature, sustainability, consumption, climate and many other topics. Voltaire could complement the curriculum in philosophy with his biographical links to gardening. The access to the fields is easy next to one of the central train stations and a larger urban reforestation project as just one example of the 15 overall in Berlin in 2024. (Südkreuz, Südgelände). Hands-on experience of gardening can address multiple forms of problem-solving competencies. Beyond the use of AI, a major advantage is the possibility to train collaborative problem-solving. Beyond the multifactorial approach in determining what to plant, the organization of the implementation and individual contributions towards the realization, all these elements are learning goals. The scope of learning qualifies gardening for learning well beyond primary school as well. It is a nice example of lifelong and lifewide learning even a hundred years after their wider applications in Berlin.
Killing me softly
The problem with pollution is, it is killing you softly from inside. It is almost impossible to escape air pollution as it is pervasive in cities, but also in the countryside where you do not expect it that much. This is the result of the study by Kuzma et al. (2024) published in “The Lancet Regional Health Europe”. Based on a data set of 8 million persons from Eastern Poland the effects of air pollution on myocardial infarction incidence was analysed. The use of the “European Union’s Earth Observation Programme” contributed data on air pollutants like PMs, BaP (benzo(a)pyrene), SO2 and NO2 concentrations. The multi-level data of 5 voivodeships, 101 counties, and 709 communities in Poland allows to differentiate the effects of damage to the heart tissue on cardiovascular disease. The other well-known factors are arterial hypertension, diabetes, obesity, chronic kidney disease, hyperlipidaemia, and smoking as most of us know already. The effects of BaP (benzo(a)pyrene) is shown for rural areas despite the lower observed traffic density in these areas. The killing occurs softly from within our bodies by just breathing in and out, and in and out continuously. The disease burden in these regions is observed with “recorded 63,154 hospitalizations and 5921 in-hospital deaths (9.4%) due to STEMI; and 76,543 hospitalizations and 4079 (5%) in-hospital deaths due to NSTEMI”. In short, the need to reduce air pollution further is an urgent demand that saves lives eventually.

Silent Pandemic
There is a pandemic that is silently spreading across countries and continents. It only indirectly related to the Covid-19 pandemic. The medical journal “The Lancet Respiratory Health” (2024) has an editorial about the inequities of asthma as they develop over the life course. The development of asthma has pre-natal, genetic, environmental, life-style and socio-economic co-determinants. The study of respiratory disease, therefore, is a multi-factorial issue, which needs to disentangle the specific influences. Smoking as well as obesity have an impact on asthma, instantaneously or with delayed time effects of sometimes many years. Hence, it is important to take the whole life course into account, if we want to address the rising disease burden of asthma. Air pollution and heating-up of the planet are important drivers of the silent asthma pandemic across the globe. The social distribution of people working in “asthma- prone” work environments and/or living in highly polluted urban, suburban or rural areas near high frequency traffic is another latent factor causing huge costs to persons and society as a whole. Health inequity is growing over the life course. This is not easy to tackle as policy target as the onset of the disease has no single trigger, but rather a combination of influences that contribute in varying amounts to the evolution of respiratory diseases.

Infinite Landscapes
The “Alte Nationalgalerie” celebrates the 250th birthday of Caspar David Friedrich in Berlin. With a considerable effort to unite in one exhibition many paintings and drawings that stem from other collections of public and private origins. This particularly remarkable as a section of the exhibition is devoted to paintings that were intended originally to be seen next to each other (compare catalogue p. 233). Comparing 2 images from the same painter evolve into a narrative. This raises curiosity as in some instances the 2 paintings do not treat the same subject. Your very own interpretations and associations will make for an individual journey through the sheer endless spaces. The exhibition allows to grasp some of the many questions posed by the period of enlightenment not only in Germany. After “God is dead” what will happen? How is mankind defined? What is its relationship to nature? Are we just left alone or what comes after individualism? Even for painters, much like scientists, it is just as important to pose the right questions. Leaving the exhibition with more questions than answers will put you in the “Berlin state of mind” of 200 years ago. Greiswald, Dresden, Rügen and Copenhagen as well as nearby mountains were influential locations and landscapes for Caspar David Friedrich. Berlin 1906 „Jahrhundert Ausstellung“ made him famous again, despite decades of being forgotten. Yet another question to ponder and wonder about. An additional merit of the exhibition is the section on painting techniques and the use of his sketches and drawings for the preparation of the oil paintings. The final riddle to be solved is the price differential between the German and English version of the catalog in the bookshop next to the usual merchandising props.
Barbie Chemical
Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.
Hannover Fair
The annual science fair at Hannover is a kind of a show of things to touch and of those things that come to the public market in the near future. Most of the annual hype is about potentials of production. Rationalization, using few resources or innovative solutions of digitization are high on the agenda. Create your digital twin, save energy, make production more safe or cyber secured.
Robotics is another reason to visit the fair. Some 7 years ago I had my Sputnik experience there. The robotics company KUKA had demonstrated live the that assembling a car from pre-manufactured components takes just 10 minutes for the robots. Shortly afterwards the whole company was bought by Chinese investors. Roughly 5 years later we are swamped by cars from China. It was not that difficult to predict this at that time. Okay, we need to focus on more value added production and take our workforces (not only) in Europe along on the way. Reclaiming well-paid, unionized jobs in manufacturing, as Joe Biden does, will not be an easy task. Robots and their programming is expensive, but skilled workers, too. Hence, the solution is likely to be robot-assisted manufacturing as a kind of hybrid solution for cost-effective production systems.
Following the proceedings of the 2024 fair we are astonished to realize that visiting the fair is still a rather “physical exercise” walking through the halls. After the Covid-19 shock we expected a lot more “online content”. Instead we keep referring to webpages and newletters rather than virtual visits and tours. The preparation of the visit in advance remains a laborious adventure. However, the in-person networking activities in the industry are largely advanced by ease of exchanging virtual business cards and the “FEMWORX” activities.
This year’s Sputnik moment at Hannover is probably most likely related to the pervasive applications of AI across all areas of the industry and along the whole supply chain. Repairing and recycling have become mainstream activities (www.festo.com). Robotics for learning purposes can also be found to get you started with automating boring household tasks (www.igus.eu).
Visiting Hannover in person still involves lengthy road travel or expensive public transport (DB with ICE). Autonomous driving and ride sharing solutions might be a worthwhile topic for next year’s fair. Last year I thought we would meet in the “metaverse fair” rather than in Hannover 2024. Be prepared for another Sputnik moment next year, maybe.

Repair Building
All buildings need repairs from time to time. For most of them the basic structure is solid enough so that isolation or maintenance will do. However, 100 years old buildings that have lived through 2 wars might have deep rooted deficiencies that are not visible at first glance. This can be observed in Berlin near the city center in a popular neighborhood with many visitors in „Schöneberg“ sometimes translated as „pretty hill“. The building at the crossroads seems to have been renovated only a few years ago, but the static of the building is so unstable that the city council has decided to block the whole crossing for circulation due to the danger of an imminent collapse of the building. The neighborhood has mixed feelings. It is great that the danger has been identified in time and blocking the road reduces the nuisance of traffic in the surroundings full of restaurants and cafes. The cover up of the repairs and renovation at the building is shocking as there appears to be just paint over basic structural faults. Construction work has failed to detect and prevent the static risks. An inspectorate that acts promptly to avoid bigger disasters is a societal asset.
Citizens Gardens
There are multiple ways to link citizens to gardens. Most people would link citizens to the property of their own garden. This is more the perspective of people from the countryside. The aim of citizens who can afford it have a garden, many others wish to have one and all of them enjoy public garden spaces. An intermediate version of the public versus private property of citizens’ garden is the joint ownership of groups of like-minded people to work together in the shared property or rented garden space. The recreational and health effects are well documented, if care is exercised with utensils etc. Spring is the ideal time to join projects again as the results of a little bit of gardening will be visible and enjoyable for several months afterwards. Gardens are also meeting points for people of all walks of life as in the vicinity of the European Parliament in Brussels. The Citizens’ Garden has a different function to people gardening there. When you puzzled about Europe after a visit to the Parliament or the Museum of the History of Europe, then it is time for a stroll and relax in the garden nearby.
Alternatively, the Exhibition Centre of Tour & Taxis in Brussels not too far away from the North train station has an impressive indoor garden for the times of rough weather conditions. At the time of the book fair culture in the indoor garden made a splendid combination. There is a green version of Europe. It is like a small plant. It needs a lot of time and care to grow. 
Forest Management
Responsible forest management is key. To safeguard against the loss of biodiversity the management of forests can achieve a great deal as the study in Nature of 2024-4-10 has demonstrated. Reducing hunting by humans in dense tropical forests allows bigger species to survive and thrive compared to forests with easy access by roads. FSC certification of forests helps significantly to protect wildlife. The ability to ameliorate biodiversity of forests is assisted by the Forest Stewardship Council (FSC) through the responsible management, preservation and limitation of access to wild forests. This is an important message that in fact it is still possible to preserve wildlife also of larger species if we only really commit to the cause. It is well worth to support such initiatives and monitor the progress. Of course, any such success attracts new hunters and a continuation of the FSC efforts is needed for the benefit of the whole biodiversity on our planet as there is no planet B.
