While there can definitely be some legitimate discussion and ambiguity over which culture/country gets to inherit Mayan artifacts, for example, saying that the British, for example, should inherit it is a very weak argument. It’s not like the entirety of an extinct societies people just dropped dead. Some survived and after some time rebuilt new societies. Using Mayan artifacts as an example, Mexico, Guatemala, and Honduras have a better claim to them then the British. It’s not propaganda or useless to say that items of cultural heritage should be returned.
So how about this what about-ism, if you live in the United States, the British took cultural artifacts from your lands too and aren’t giving them back right this moment. Where did you think all those native American artifacts in British museums came from? They didn’t make them and it’s not like North America was spared from British plundering. Might be nice to get that stuff back.
It depends on the bacteria, when in it’s lifecycle half of it is killed, and what half is killed. To keep things short, the odds are in the bacteria’s favor. Suppose if half the bacteria in your gut died right now how long do you think it would take for the bacteria population in your gut to return to pre-snap levels? A month? A year? Decades? How about less than an hour. Bacteria reproduce exponentially and on average, a bacterial generation lasts 20 minutes. Meaning that every 20 minutes the population doubles, assuming there are no deaths in the population during this time. If there is space for bacteria to grow, they will.
