You read too much news. The news is designed by the ruling powers to make people lose hope and thus make people more easy to subjugate.

If you lived in WW2 or the US-Soviet Cold War, you would've thought the world was ending.

Hey you know that the Earth is eventually gonna get sucked into the sun (or flung out into space, not quite sure which is which) and everything here dies, right.

Everything is temporary.

One of the leading theories of the universe says everything will end in "heat death". So, with knowledge of this, do you just decide to give up since "everything is meaningless"?

Fuck that lol. We shouldn't be alive, the odda s arent even in out favor, but we are. So, TAKE THAT, STUPID UNIVERSE.

I'm alive and being alive is a rebellion, its rebellion against the universe.

P.S. I was born under the Once Child Policy of mainland China. I wasn't even supposed to be born, since my parents already had a child (aka: my older brother). But guess what, I'm alive. So, take that, CCP. Sometimes, I have existential thoughts about the "what if"s, like "what if I was never born". But you know what, fuck that. On this timeline, I'm alive. My life is inherently a rebellion against authoritarians, its a direct contradiction to the CCP's policies. I shouldn't be worrying about a timeline that never happened, and similarly, we have to stop resigning ourselves to a failure that hasn't happened yet, its never too late to try to fix it.

For some pespective, even if the all the polar ice caps melt and we detonated all nukes on earth, Earth would still be more habitable than, say, Mars.

So, do what you can to stop climate change, don't be too sad about it, everything eventually dies, just try your best. Be a rebel against the universe, be a rebel against authoritarians.

Do yourself a favor, and live long enough to see the demise of tyrants, and then keep on living to piss on their graves :D
