This. Earth left for the brown hordes (except China maybe), Mars for keeping the light of civilization alive.

Musk is from South Africa, and he knows what is happening in that country, so he left to the US. Now the same thing but in slow motion is happening to the West in general, and Mars colony will be the escape.

200 million kilometers of hard vacuum is the best immigration policy.

melanites wont stop breeding, and climate change will result in (((politicians))) inviting an unabated swarm of borderline apes into higher latitude states, washing out the higher races and drowning the world in darkness

We could solve a lot of problems if gene therapy could fix genetic diseases. Pic related is a great filter and the only way to stop it is by using gene therapy to artificially boost intelligence.

>Why don’t climate change activists ever talk about India, China and Vietnam?

Because even you are woefully unaware of the REAL crisis, the African Population bomb.

Eugenics is the only way to prevent a dysgenic collapse of civilization in the long term, Idiocracy style. Too bad it got unfairly tarhished by association with the nazis.

However, we almost have the technology to implement eugenics by routine whole genome sequencing and embryo selection. No need to sterilize people nowadays. So maybe there is a chance.

Idiocracy is coming.

Idiocracy is what we will become.

Africa is not allowed to grow because they are growing their population into a way larger total than Europe and America, and because they are stupid on average (IQ 70-80).
