applies on a large scale: remote sensing, but also environmental samples of the microbi
ome of ecosystems (metagenomics) not only create new floods of data, but I also know
more and more precisely where which object is located and how it is currently changing.
This also makes it increasingly possible to understand how our environment is chang
ing and in what direction. This also increases the possibilities to actively change it. We
must not be under any illusions. Even if we all “do nothing” (Plan A: “Business as
usual”), the general activity of humans has a strong influence on our environment locally
and also globally on the climate and biodiversity (Barnosky et al. 2011).
At present, it is clear that we have not yet achieved this stable basis for life. We are still
living on borrowed time. We are steadily increasing our carbon dioxide emissions, we are
struggling with global warming, overpopulation and dangerous nuclear armament, raw
materials are becoming scarce, and electronic waste and environmental toxins are on the
increase. But for these complex problems, there are good answers not only from technol
ogy, but also from biology and bioinformatics. It is clear that this must now be imple
mented decisively before our basis of life is irretrievably damaged and our current,
outdated technology collapses, but also positive trends become visible (Lehman et al. 2021).

Model and Mitigate Global Problems
Bioinformatics approaches can contribute a great deal to global problems. This is because
our entire world can also be viewed as an overall ecosystem and modelled in systems biol
ogy using computers. In addition, all the typical steps that otherwise have to be taken in
bioinformatic modelling are there. In particular, one is forced to simplify strongly in some
cases. One performs many simulations, and when the solution space becomes even more
complex, one tries to represent and explore important combinations of conditions in indi
vidual models (so-called “scenarios”). Important problems, unfortunately, arise especially
because of our success as a modern, technological civilization. This success, and in par
ticular a certain prosperity, was increasingly achieved after the Second World War. This is
also centrally important to pull the poorest strata of humanity (these have only one dollar
a day at their disposal) out of hunger and disease, especially since only with four dollars a
day of earnings is it possible to go to school and with 16 dollars a day to study, and only
with at least 32 dollars a day is there so much prosperity that there is time for reflection,
reading and real planning for the future (Rosling et al. 2019; illustrative: there is only dif
ferent prosperity, otherwise all cultures are always the same people, to be seen in Hans
Rosling’s “Dollarstreet” https://www.gapminder.org/dollar-street/). The solution must not
be to go back to the past (after general collapse only hunger and suffering) but to advance
sustainability, digitalization and environmental and species protection as well as interna
tional cooperation and education. This is particularly important in the case of the five
systemic risks of global war, global warming, economic crisis, pandemic and dictatorship
(supported by digitalisation, for example). In contrast to smaller catastrophes, the systemic
risks pose the danger of weakening our civilisation as a whole to such an extent that a
downward spiral can occur.
