As a non colorblind person, I would like to understand how this image could have been modified to include our colorblind brethren.
In general it is a good idea to use colour gradients that monotonically increase (or decrease) in brightness in addition to (or instead of) hue (see here for an in-depth comparison of different colour maps. It’s from a Python package, but it shows some interesting plots comparing different colour maps when it comes to brightness vs. hue). This isn’t just useful for colour blind people, but also helpful when printing in black-and-white.
If you absolutely have to use a diverging colour map, you might reach most people by using blue as a major component of one, but only one of the two branches (the map in the OP uses blue as a major component of both branches, which is why red/green colour blind people can have a problem with it). That way most colour blind people should be able to distinguish the branches, since blue colour blindness (Tritanopia/Tritanomaly) is much rarer than red (Protanopia/Protanomaly) or green (Deuteranopia/Deuteranomaly) colour blindness.
Apart from that it is also possible to mark information visually in other ways than by colour, e.g. by shapes and patterns, like dotted or dashed lines for line graphs, shaded or dotted areas for bar and area graphs, or different geometric shapes like crosses, diamonds, and circles when plotting individual data points, but that is probably more useful when different sets of data are plotted in the same graph.
In what world is a country with billionaires and an autocratic ruling class in which the workers decidedly do not control the means of production, “socialist”?
i read that something like 1/3 of all human caused extinctions are because we keep bringing cats with us
Do you have a source for that? Intuitively 1/3 of all species extinctions (keep in mind this in general includes plants and other kingdoms of life, not just animals) sounds far too high imo. Maybe you have read that number in a slightly different context, like bird deaths in urban areas, or perhaps in a more specific context similar to the one in your link? Don’t get me wrong, like your link shows, (house) cats can easily have a devastating effect on the local wildlife, in particular birds and small mammals or reptiles (wikipedia has an article on the topic, although I didn’t find anything like your numbers in it). But as far as I know the major ways in which humans have caused extinctions are historically overhunting (mostly affecting large birds and mammals), habitat loss in particular since the advent of agriculture, and more recently of course the effects of the climate crisis since the industrial revolution.
Humans have put multiple species on the verge of extinction.
That is a slight understatement:
Why would taxing a gross income of above a billion US$ by ~66% be “completely unreasonable”? Imo taxes for such incomes should generally be higher if anything.
