Forest sponge

Forests work like sponges. They can stock enormous amounts of water. Trees, even when cut years ago, keep a lot of their humidity, especially if they are underneath other trees. A rich nourishing soil allows biodiversity to thrive. It takes years and sometimes decades for these ecosystems to grow, but they are destroyed within a few months or just days in case of wildfires. We have to put higher monetary values on these ecosystems and their contributions to biodiversity in order to make the preservation economically feasible as well. The sole ecological value does not seem to stop us humans to exploit this resources beyond sustainability. The succession of seasons should be a reminder of the essential role of circularity in nature and a principal of conservation of biodiversity.

Fire engines

The collection of fire engines model cars on display in a Berlin antique shop reveal the whole dilemma of fire fighters across Europe. Lots of different models and technical specifications mean lower potentials for synergies. European cooperation is such a strong statement of hope and solidarity during emergencies. Better coordination in joint acquisitions would allow fire fighters from each Member State to be operational in other units. The power of the many could be a significant advantage to fight the fast progression of fire we have witnessed in 2026-7.

Fighting fires

In our homes and offices we are used to have electric, digital and chemical devices to assist us in fighting fires. Fires can have multiple origins ranging from faulty technical devices to human errors, behavior and volition. Some countries have terrible experiences with city fires engrained into their history. The scale of wild fires in forests in Europe, the USA, Australia or Canada have reached a new dimension. With global warming fires known in southern parts of Europe reach further north and become more intense. The fire near Fontainebleau (Forêt de Sénart, France) in 2018 destroyed 9000 hectares forest. In 2026 the fires near Bordeaux burned 10 times the size (Link). There were about 8 years to get prepared between the 2 large scale incidents. The technocrats’ answer usually is just limited to the immediate surroundings of the fire. Instead larger scale actions have to be prepared and enacted to prevent the next incidents. The technocrat’s answer is more technology like aircrafts and yet bigger aircrafts(still largely insufficient in 2026-7). Satellite and drone surveillance with infrared cameras additionally can go a long way, but the human factor remains a hard to fight beast in all such technical fire fighting scenarios. This setup seems to be somehow like a constant to take into account in all technological propositions.

VOC for VCs

The research into VOCs (short for “volatile organic compounds”) is a busy research field in biology and environmental sciences. It might be of interest to VCs (short for “venture capitalists”) as well in the near future. VOCs are those organic compounds that orginate in animal manure as well as those emanating from plants have an impact on people working there or who are living nearby. Allergic reactions cause millions of days lost in working every spring or summer season. Long-term effects are yet another critical issue in this respect. Whereas the measurement techniques of VOCs have evolved a lot, the interaction effects of different VOCs are slowly producing interesting results that might eventually become of interest to VCs.
Abonde et al. (2026) show that there is a kind of communication between different plants via VOCs, which has an impact on growth and defence mechanisms of some plants. Amateur botanists have always wondered about the anecdotal evidence that some plants or flowers grow well next to each other, whereas other ones seem to deter each other. For crops, this mechanism has been documented and more experimental research of this kind will corroborate the potential of, for example, “natural fertilizers” in future. Remember to think of VOCs the next time you experience scents from animals, plants or flowers as a wonderful research topic with VC potential.

Set and Match

The organizers of big tennis tournaments like at Roland Garros in Paris have to reach ever bigger audiences to be able to cash out the prize money for the top players and their expenses. Besides the number of spectators on site, the prime income comes from television rights and sponsorships through advertising. Gambling on set and match is also a rising annex market, just like tourism linked to the event. For such purposes Paris offers screenings, similar to the Olympic Games 2024, in the centre of Paris. The park “Les Tuileries” offered to follow the tennis matches on big screens against the background of the Eiffel Tower (image below). Of course, the “rue de Rivoli” nearby offers additional pleasures or take home goodies for spectators, which add to the overall budget spent by an average tourist in Paris. For people interested in a walk in “Les Tuileries” and the plants ( Acanthus), trees (Linden) and flowers (roses) have to choose the other parts of the park. Big cities have the chance to offer a bit to everyone within relatively short walks. 

Polychrome tree

Maybe it is just a matter of taste whether you prefer a tree polychrome i. e. in full colors in spring or more monochrome during winter in almost black against a white background. Others might argue that it is not a singular version or time of the tree’s growth cycle, but the steady change. In any case the same tree never looks the same before and after rain. The only certainty is “the times are a changing”, so do our preferences. They are changing as well from time to time. Few persons have similar preferences over the life course and business, marketing and societal changes drive such changes. Often we hardly notice them. Trees are a perfect point of reference to check your personal preferences. Our smartphones track our preferences just by analyzing frequencies of photos taken over months or years. They have a very differentiated polychrome view of us. The reasons to take ugly pictures might confuse the AI-assisted exploitation of our polychrome or monochrome preferences. 

Fontainebleau walks

In the Fontainebleau gardens it is easy to reach your daily walking goals of 7000 a 10000 steps/day. Upon entry into the park you walk around the small lake. Towards the far end of the lake you’ll discover a long waterway which takes you beyond your usual walking distance due to the calm and great surroundings. The forests around the Fontainebleau gardens are another great walking or hiking exercise. You might find companions all along the trails. Just take enough water and food with you as there are no shops around, just you and nature. A bit of advance planning is necessary to make it a great experience. 

Warming continues

The global warming continues to change our landscapes. Heat waves, droughts and flooding become more often. Average temperatures keep rising. The evidence from meteorological data is showing this beyond doubt. Our forest take the toll and reports document the worsening situation for many trees (Germany and Switzerland). An adaptation will take years if not decades. In the region around Paris some home owners have started or been forced to adapt their gardens to the warming weather conditions. Trees that do not support the consequences of warming die and we witness the changing of the landscape. Palm trees near Paris have survive for years by now near Paris and can grow rather tall.
Like it or not, the visual landscape will change despite the many great initiatives launched by the city of Paris to stop the warming of the city.

Warming consequences

The live of honey bees is rather busy and well organized. Global warming necessitates new risks and new opportunities for honey bees. The flowering season starts earlier in Europe and bees start earlier ro their collection of nectar and their service of pollination to other flowers. In early April 2025 in France near Paris we observe wild bees already in their daily routine. However, the risk of cold nights is still there, albeit those building their homes below the surface are a bit less at risk during a frosty night. Seeking a clever shelter is a good strategy for survival particularly at times of global warming. Some kinds of wild bees seem to sense this already changing homes from one season to next one. Humans remain their toughest enemies as they restrict their choices quite severely. Man-made pollution and herbicides are beyond bees’ control and cause havoc in the ecosystem of bees. Apiculture is an interesting science also for social scientists as this forerunner species of the matriarchy has evolved into a well-organized productive society. They are a bit harsh to each other and communication is rather unidirectional, but an interesting social cosmos of its own kind.

Olympics for All

The Paris 2024 Olympic Games and the Paralympic Games have demonstrated the extraordinary competence, professionalism and competitiveness of all athletes. The television spectators and live participants in the events have been involved to a great deal.
After all this hype around sports let us consider the probability of getting involved in physical activities and sports. Additionally, it is of interest, whether people are encouraged to continue sports, maybe at higher ages as well through these sports events like Olympia.
High level athletes are most likely to continue their sports activities. In many countries the extraordinary athletes of the Paralympics faced tough challenges to pursue their sport interests and passion.
However, the public health challenge is the big unresolved issue of how to best raise an awareness for the pleasures and benefits of sport for the masses. (bibliography by BNF “Santé et activité physique). It is not only a matter of suitable infrastructure, but also the question of sports in your neighbourhood. This issue has implications for urban and rural communities and how they organize the practice of sports in an inclusive way. Each step may be a stepping stone into sports for all ages and pathologies.
The pleasure and benefit to walk or something simple as walking to or walking after work, are part of the solution to many public health issues.
The visitors of the Paris Olympics walked a lot.
This fun experience in an enthusiastic city will encourage many to continue the simple exercise without thinking about exercise. This will do the trick. Just do it, without thinking to much about it.
