A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

- Use NSFW marking accordingly
Laittakaa meemejä tänne.
- Odota ainakin 2 kuukautta ennen meemin postaamista uudelleen

I think it’s a variant of #2: the ozone layer is much more susceptible to damage from space flight than we yet realize, and it’s a trade-off between keeping a hospitable home world and interstellar travel. By the time a species is scientifically advanced enough to be technologically capable of it, they learn the risks and decide it’s not worth it.
