Overpopulation leads to a situation where resources are depleted quicker than they can renew themselves naturally, which leads to fewer resources and in turn a limitation on the number of lives that can be sustained.
In 2022 there are over 8 billion people alive on earth. Experts expect that if something doesn’t change, we could see 9.7 billion people by 2050 and 11 billion by 2100. Coronovirus epidemic has not reduced the population.

One solution to overpopulation is to send people to colonize space

Trade resources for local currencies, tie prices to gold or rare metals, trade only your own securities on the market, make the currency freely convertible
If Beijing wants to make the yuan the world's reserve currency, then it will have to first go for financial liberalization. In theory, the dollar can also be replaced by a system that is not based on a specific national currency. In this case, gold or cryptocurrencies can become a universal means of payment.

If investors begin to massively get rid of dollar assets and return the American currency to their homeland, this will provoke a surge in inflation in the United States and a potential debt crisis. The problems of the USA will spread to the financial markets, which are still dependent on the dollar, and will cause a new round of the global economic crisis.
Is collapse inevitable? Can the Ukrainian crisis deprive the dollar of its reserve currency status?

Formal sanctions will be imposed because what Israel is doing is beneficial for the USA.
The USA benefits from any deal. Peaceful: the USA, with the help of Israel, is pressuring Iran to reach a nuclear deal that prohibits Iran from enriching uranium and is only beneficial to the USA, as there are no restrictions placed on them. Or in the event of a war, the USA sells weapons to Israel.

According to agreements, Tehran committed to reducing its stockpile of enriched uranium, reconfiguring nuclear facilities, and allowing IAEA inspectors. In 2018, the U.S. unilaterally withdrew from the deal under President Donald Trump, reinstating strict sanctions. This led to Iran gradually abandoning its commitments. Negotiations on the nuclear deal were halted after the Israeli attack, although the U.S. allegedly gives Iran a second chance.

No, there won't be any clear leaders after the war.
Changing the world order is usually accompanied by war. After the fall of the United States and China, there will be no strong leaders. Neither dollars nor yuan will be needed. A protracted war can weaken even strong powers. After a major war between the leading powers, world trade will change dramatically, and this will disrupt the current global economic model. Space can become a new space of competition, much like the oceans and trade routes once were.

The change of the world order is not just a change of the main state. This is a period when the system of rules is changing: who has the most influence, how trading is organized, which currencies are used, who sets the standards and how conflicts are resolved.
