3.2 Legal basis The legal basis is Article 6 Paragraph 1 Letter e GDPR.
3.3 Duration of storage All data is recorded only within the learning application. They are stored on the HTW-Berlin servers and will be deleted when the project or possible follow-up projects expire.

Das Wachstumsmodell
Die Weltbevölkerung wächst und dieser Prozess kann man mit Hilfe von Exponentialfunktion (wenn auch sehr vereinfacht) modellieren. Folgende Formel hilft dabei die zukünftige Population \(P(t)\) nach \(t\) Perioden mit dem Anfangsbestand \(P(0)\) und Wachstumsrate \(r\) pro Periode zu verbinden:
\[ P(t) = P(0)(1+r)^t \] dabei kann \(r\) positiv oder negativ sein. Ein negatives \(r\) würde bedeuten, dass die Bevölkerung schrumpft. Im Jahr 2000 betrug die Weltbevölkerung etwa \(5,2\) Milliarden mit \(r>0\), demzufolge weist sie ein positives Wachstum auf. Je nach dem, welche Schätzung zugrunde gelegt wird, gilt \(r\approx 1.6\%\) pro Jahr.
Im Jahr 2021 lag aber die Zahl der Menschen auf der Welt bei \(7,85\) Milliarden (Quelle: Statista).
Die Wachstumsrate
Die Weltbevölkerung im Jahr 2000 kann man natürlich nicht im Nachhinein verändern. D.h. die Wachstumsrate muss anders gewesen sein!
Wow! Die Weltbevölkerung wächst rasant! Man fragt sich, wann die Marke von 10 Milliarden überschritten wird…
