This isn't really a problem, because most people live in the Northern hemisphere (Europe, Asia, and North America).

This involves co-evolution where prey and predator evolve together. A caterpillar becomes poisonous and then a certain bird learns to not eat it. The bird may have trouble telling the difference between poisonous and non-poisonous caterpillars. The poisonous one may change color to help the bird tell the difference between the 2. The non-poisonous one uses camouflage while the poisonous one choses a different color which may be a bright color. It doesn't consciously choose a color, but it is easier to understand when I phrase it that way.

I'm not sure about phrasing this issue in psychological terms.

> consider doing a “spring clean” every year, and schedule a time to spring clean your digital footprint

In January, I moved stuff to a directory called "\Old\2021" and deleted some stuff from active directories. I didn't delete anything, so I'm still hoarding, but at least I got stuff out directories I use every day.

> reduce unnecessary digital content

Searching for duplicate info is a pain. Occasionally, I'll do it, but I don't catch everything.

> come up with simple mechanisms to organise your files, emails, pictures and videos

I do that, but I still hoard. It takes time to label pictures; I rename files to include a description. I also use folders. I copy pictures from my phone to my PC, because I have a system on my PC. Periodically, I'll delete some pictures from the phone.

This is an unrelated issue.
