I used to worry about things a lot — the environment, feminism, politics, et cetera.

Now i don’t worry so much. I don’t have any kids, so i’m not worried about the world for them. Whatever bad stuff is going on right now will certainly work itself out eventually — give it a few million years, and everything will be fine.

Humans are not a big deal to the Earth. The species as we know it now is probably only about 300,000 years old, with roots going back maybe 2 million years. [AI for the numbers]

The Earth is 4.54 billion years old and has had life growing on it for at least 3.5 billion years. [AI for the numbers]

Earth has been habitable for reptiles for approximately 320 million years and for mammals for roughly 225 million years. [AI]

So a couple million years isn’t a big deal to the Earth — less than 1% of the time gone by (for mammals).

And …

The Sun will not go nova because it is not massive enough to explode. In about 5 billion years, it will swell into a red giant, then shrink into a white dwarf, and eventually become a cold, dark black dwarf. [AI]

So we have some time yet; enjoy it while it lasts, humans.
