Hint: it is not CO2

China is the largest consumer of concrete, and they build a lot.
Because buildings have value, it is a way to create quick money in their weird economy.

In China they add also a lot of sand to the concrete.
That is why the Chinese buildings fall apart.
But you don't hear about it on the Chinese media due to the immense censorship.
Instead you see news about how great the economy is doing, mainly due to the imaginary value of all the hazardous buildings.

That censorship and propaganda is kind of similar to how we (in the west) are continuously warned about CO2 and climate.
It is all bullshit.
There is absolutely no science in it, but young "scientists" are easy manipulated to support it, because there are some cycles that take a few generations (50 years).
Young "scientists" are also very eager to get their career going, and writing bad things about CO2 or farmers or concrete is really giving them a lot of social credit in the system.

But scientists that look a bit further than the funding or the hype, can tell you very clearly that it is all a scam. CO2 is very low to what it has been historically. And the temperatures are very low compared to a few thousand years ago.

The scam is simply meant to fully control the energy system and convert it to a complete monopoly governed by "elites".
They also want to control the water supply, the food supply and everything else.
