Small things, big effect
Dialogue Forums 2021
They are tiny but still cause a lot of fuss: viruses, bacteria, fine dust, microplastics or even CO2 molecules. Small thing with a big effect: That is definitely true for all of them. Viruses trigger pandemics. In Germany alone, fine dust kills as many people as road traffic accidents. Microorganisms have a decisive influence on the geochemical cycle of the earth and the smallest microplastics can be found in many of our foods. Tiny CO2 molecules are mainly responsible for man-made climate change.
Reason enough to look at these very small things under a very large magnifying glass. In the 2021 dialogue forums, we and our experts literally go into the smallest detail: We show important connections and explain how tiny organisms, particles or molecules unfold their great impact on humans and the environment every day.
The moderator of all events is Dr. Patrick Illinger, Süddeutsche Zeitung Munich.

The Corona crisis is only the most recent example: In our globalised world, tiny pathogens can spread at breakneck speed across all continents - with fatal consequences. How do viruses, bacteria and parasites differ and what makes us sick in the first place when they attack us? How can we protect ourselves more effectively and prepare better for future pandemics? And what have we learned from the Corona crisis so far? Washing our hands is not enough!

Whether in the oceans, in our rivers, in soils or in cosmetics: Microplastics are everywhere and are changing the entire biosphere of our planet. The water-insoluble plastic particles are smaller than five millimetres and have long since entered our food chain. How can we stem the flood of microplastics? How dangerous is microplastics in our food? What needs to be changed in our national and international environmental legislation? Can micro-organisms be used to break down man-made plastics such as PET?

Fine dust is a natural component of air. However, combustion engines, tyre wear, industry and power stations are causing the concentration of particulate matter in our environment to rise enormously - and can trigger massive health problems. Scientists have already succeeded in detecting fine dust in human cells. In addition, soot particles contained in fine dust are extremely harmful to the worldwide climate. Who are the biggest emitters of particulate matter and how can the pollution be reduced? Do we need stricter limits - in the EU and worldwide? How can I protect myself from fine and ultra-fine dust?

Carbon dioxide - a small molecule at the heart of the current climate change debate. The CO2 content of the earth's atmosphere is constantly rising and our way of life is playing a major role in this. The increase in CO2 concentration in the atmosphere is closely linked to the observed rise in average global temperature - including changes in climatic patterns. How exactly does CO2 influence the climate? Which options do engineering solutions such as Carbon Capture and Storage (CCS) offer? Are these approaches useful and target-oriented? And how effective are the nature's CO2 sinks?

5G is the new magic word. Not only the mobile phone industry is electrified by it, but also a large part of our society. With modern technology one hopes for an undreamt-of increase in data transmission speed. The exchange of information should be even better, smoother and faster. Critics, on the other hand, still see major deficiencies in the infrastructure. Many also fear the new technology because of potential health risks. But also infrared radiation, which we have been using for a long time, affects our environment. What exactly is the effect of infrared radiation? Can mobile phone radiation or wireless networks really make people ill in everyday life? And how exactly does medicine make use of such "dangerous" types of radiation?
