>he doesn't know that by 2030 41% of live births will be in Africa, 40% of all humans under five, and 37% of all humans under 18 will live in Africa
>he doesn't know that even low-end UN projections models have well over 50% of all humans under the age of 18 being African by 2100. That is, living in Sub-Saharan Africa, which will have more people than all of Asia by then, eventually eclipsing all of Eurasia and Australia early in the 2100s.
>he doesn't know demographic projections have been quite accurate sans major war or migration
>he doesn't know this includes 200 million Africans leaving for unnamed locations due to climate change and economic reasons.
>he might know that the UK, France, and Germany will all become majority non-European by around 2080, but he probably thinks of MENA migrants when it is in fact black Africans who will become the plurality group after Whites decline, on a path to becoming the new majority shortly after 2100.

You fail to realize what has already changed. Half of all children born will soon be Black. Migration will increase massively because the pool of people that created the 2015 flows was well under a billion and will rise to several billions, with all the net growth being Black.

BBC already IS the ultimate revolutionary advantage. Look at the growth for large cities.

The replacement of Whites as the majority of Europeans from the advent of mass migration in 1970 to around 2100 will have taken substantially less time than the replacement of Native Americans. The shift won't be to multiracialism with Whites as the largest group, that period will be just 20-40 years. It will shift to majority Black.

Talk about some massive reversal if it makes you feel better. Some sort of garrison state, walls and armadas all around Europe. It won't happen. Pensions come first and migrants will be needed to keep wages down and rents up so that the Boomers get their returns and the elites are happy.

BBC won.

*Surfing retirees to working people

Also, Africa will dominate European and world history from 2030 on.

Sub-Saharan Africa just passed a billion people in 2015 but is on track for 4.3 billion in 2100. Long term demographic projections are actually fairly accurate except when war or migration dramatically effect them. At the same time this population booms, climate change will begin hammering the region, sending hundreds of millions looking to migrate. This is 2015 x 50 in terms of flows.

Africa will also drive world economic growth because:

1. Currently rich nations will all slow dramatically due to aging populations and huge pension liabilities.
2. Poor countries that haven't hit diminishing returns on capital have higher growth potential due catch up growth.
3. By 2100, over half of all humans under 18 will be African, but they start making up more than a third of all young people even earlier.

The later 2020s is when US retiree expenses really explode while college enrollment peaks and then plunged in 2025 due to less young people joining the pool. Europe has an even harder drop off due to less migration.

This will cause major political instability as nativists attempt to put minority rule in place and falling living standards and surging inequality (migration helps the pension problem but hurts equality, trade off) drive politics wild.

Forget the 2020s, a crisis dwarfing WWII later this century is staring us in the face.

Give it to me straight /sci/, is overpopulation going to kill us and cause an ecological disaster?

We're going to add billions more in the coming years.

>Inb4 innovation
Innovation to stop pollution requires wealth though, look were the population growth is.

Sub-Saharan Africa just passed a billion people in 2015 and is going to perhaps have more people than all of Asia by 2100. Pic related is people aged 18-59 population.

By 2100 more than 1:2 people under 18 will be African. By just 2040 2:5 children born in the world will be born in Africa.

So it seems like stopping ecological disruption might require wealthy nations to share to get any innovation stood up abroad.

I am doubtful. It seems like we are sleep walking into a disaster.
