Examination of the World's Population with Joel Cohen

Professor Joel Cohen: Abby Rockefeller Mauzé Professor of Populations, Rockefeller University, Mathematical Biologist, Columbia University

In the next fifty years the world will face population problems that it has never faced before. Billions will live in mega slums without access to clean water or medical care. In his lecture, Professor Joel Cohen teaches you how demography can provide answers to the life or death questions caused by the world's swelling population and dwindling resources. Can we prevent an outcome where wealthy western countries are in permanent population decline, while third world cities into swell into massively overcrowded slums with no access to education, healthcare, or hope?

Dear professor Joel Cohen thank you for the ray of hope for brighter future of humanity. I hope graduates from your program are in every government cabinet. They should have real power to implement the strategies they were taught; otherwise all is lost.

What are we going to eat if we all move to the cities?

[WartsG]

I'd like to acknowledge the fact that a great deal of research and analytics, I found this refreshing and fascinating :) thank you

Absolutely wonderful lecture. Cohen is logical, factual, good-natured, and optimistic. Facts and reason beat ideological preconceptions .The critics from left and right who are rejecting him should pay close attention.

Professor Cohen, I notice you focus only on "poor" and "rich" countries. What about emerging economies and the economic differences inside those countries? Hong Kong has today PPP USD$46, 299 GDP per capita, Shangai $20, 313, Guizhou USD PPP $ 4, 674. Also, there are countries that overcame poverty and achieved development like South Korea, Singapore, and Taiwan. I admire your insight, but I would appreciate a more detailed analysis on middle income countries, which make up for 5 billion of humanity

Please YT this debate is so important, don't silence it because of political correctness, THX.

[tapyouout]

Outstanding and incredibly important lecture. Thank you Professor Cohen.

[bystroffc]

Can I learn demography as a senior level professor? As a biochemist? Yes I can. Thank you Professor Cohen.

Let be honest Africans can support themselves with all the untapped resources they have got, It's just we want those rescuers for ourselves.

[adotburr]

Did he just state fear of losing his favorite nudist colony in New Jersey?😳😂😂

[IceFurnace]

really? which scientist measured that from space and how?

[willempasterkamp]

If you look for a debate about population here on YT you find almost all reactions closed by YT. SHAME YT.

He's also not taking into account the peak oil/gas, and peak coal is going to make us have to become more rural (closer to the food sources), not less rural. So he's right in the short run view that he contemplates (through 2050), but you go to 2150, and it's the polar opposite - we're going to have to become much more agrarian in the developed countries than we are now, just to survive. There simply won't be enough gas to transport the food everywhere.

"pull up your pants, and get to work" very insightful!

[ChickpeatheTortie]

We should all become vegans,  the animals would certainly appreciate it and its not just the huge amounts of grain that are used to feed these poor brutalised creatures but it also takes up huge amount of fresh water we also need to recognise that other species have just as much a right to life on this planet as we have

Excellent Video Joel sir what a excellent prentation of valuable information, I have shared this video with as many as people in as many as ways, we (Humans) really need to combine Technology, Economics, Social Psychology to reduce population to be disciplined to take care of Environment and to use Natural Resources carefully. Joel Sir Hats off once again, excellent Video
