What can happen when world population reaches 18 billion?

The world will not reach 18 billion people, for the same reason that you cannot sail a yacht in your bathtub.

Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. This is based on mass refusal to give up eating meat. Around 10 billion people is the uppermost population limit where food is concerned. It's probably not quite even that many. The truth is that nobody really knows, but a world with 18 billion people would mean a lot more people starving and living in poverty, which would mean far more conflict. Things would be bad!

While it is said that all (current) 7.3 billion humans could fit inside of New York City, space isn't the issue. (And that's a terrible idea!) The real limiting factors are finite resources, especially food and water.

Other factors for limiting human growth on Earth are the nitrogen cycle, available quantities of phosphorus, atmospheric carbon concentrations, not to mention fossil fuels or whatever replaces them.

The good news is that the UN says we are a population close to being in decline. Globally, the fertility rate is falling to the replacement level of 2.1 children per woman, which is the rate at which children replace their parents and make up for those who die. If the global fertility rate does indeed reach replacement level by the end of the century, then the human population will stabilize between 9 billion and 10 billion.

Mtchew another nonsense. Were they not thesame scientists that predicted end of the world.. They eat gworo a lot.

There is a grand plan to sustain the world through the scheme of survival by elimination. The rich cabals do not want anything that will threaten their position in the food chain. Yes of course, The world will never reach hit 18 billion peeps, rather it will shrink and in the process wipe off the weak.

Maybe we will reach the apocalypse day

Cannibalism will now take over!!!

Or introduce another biological weapon

The world won't be that populated, a combination of nature and viral outbreaks will keep the population in check.

Haven't you seen enough movies ?

Earth can still take more than 15billion.
But we really need to start investing more on science instead of religion that has never done anything for us.

Imagine donating all the money we spend on churches or mosques for the course of science.
Those mega churches are turned to mega science laboratories and research facilities.

Human would have successfully explored other planets and maybe colonised them.

That's why they say, religion slows down science.

Some quarters attribute the growth in global population to a certain fast-growing religion

OK. I'll msg you when I get on Kik.

Who cares what happens if global population hits 100 billion? Religion said multiply and fill the earth. We are going to marry more wives and have as many children as possible even if they end up as almajiris, armed robbers and prostitutes. No statistical research should save us from this self destruct mode. We are obeying the bible.
