The Risks of Overpopulation

I kinda miss these older videos that were at a slower pace. I know it doesn't bring in the view numbers and fit audience retention rates, but it's a nice change if you want something a bit slower paced and more detailed.

Using this as inspiration for an essay and realized that this video is so old that almost every source linked does not exist anymore. Congrats on staying relevant Hank. Keep up the good work.

We just broke 8 billion. 1 billion people people in 10 years.

When he said “ 7 billion people” I thought “ damn this videos old”.

A large help would be to move our intercity roads under the surface, allowing large swathes of land to return to nature.

and all these new people are 4 yo already...damn

Japan is me. "Why aren't you having any babies?" "I don't know. I don't feel like it."

All of those babies just turned six! 😄

Although equal, free/cheap food distribution sounds pretty neat, it actually isn't. For the past 50 years the US and the EU exported food so cheaply that some really poor countries, especially in Africa, didn't see the need to develop their own agriculture any further. Small farmers could not compete with the cheap imports, went out of business and became even poorer. End of story when prices for grains increased dramatically in 2007/08 a lot of people in developing countries couldn't afford bread anymore, because they were so dependent on the world market price. In developed countries we are capable to produce food mountains but rather than shipping them, we should give knowledge and technology to the people in need.

9:29 and that's exactly why i want a hell of a lot fewer births. seriously people, how about instead of jumping through hoops have your own baby, how about you grow a heart and a brain and adopt instead to take care of the people who are already here

8 years later and we're closing in on 8 billion already. 7.84 billion human beings. Absolutely incredible.

Imagine having 15 babies, expecting 5 of them to live, then the industrial revolution happens.

Actually, I did the math. Let's say we count to a billion to begin with. It would take 1 billion seconds to count to 1 billion, if you counted one number per second. But, we're counting 2.5 numbers per second, but forget about that for a minute. Let's stay with the 1 billion seconds. Divide 1 billion by 60, and you'll get the amount of minutes it would take. Divide that number by 60, and you'll get the amount of hours it would take. Divide that number by 24, and you'll get the number of days it would take. Dividing that by 365.25, and you'll get the number of years it would take. To count to 1 billion, at a rate of one number per second, it would take about 31.68 years. Let's divide that number by 2.5, to get the amount of years it would take to count to a billion, at a rate of 2.5 numbers per second. The number would be about 12.67 years. So, we need to find out how much time it would take to count to 6 billion (the number of people born withing 200 years after the first billion people, [3:57] in the video). We can just multiply the 12.67 years by 6 to get our answer. The amount of time it would take to count to 6 billion, at a rate of 2.5 numbers per second (which is quite unrealistic, as no one can say some of the bigger numbers out there 2.5 times a second), it would take a grand total of 76.05 years.  That means (as far as I can tell), that for every 76.05 years from this point, the Earth's population of humans will grow by about 6 billion people, every 76.05 years (if the rate of babies being born stays the same).

I know this is an older video from you guys, but I just found your channel, and I absolutely love it!!! This is an awesome and informative channel, and I'm addicted!! Thanks guys...and now I'm off to binge all the vids and become a Sci-fiend!!! Lol!!

I remember seeing this video when it first came out back when. I'm glad scishow is still around. Do I sometimes miss the older, a little more looser format, yes. But I recognize longevity has a price, and I'm pretty pleased to start pointing my nephews who are now in the double digits at your content.

4:30 lol what happened to your hair? You look like Jimmy Neutron in that part haah

Dear scishow, thank you for all of your insightful videos. I like learning with you guys

I have never watered my lawn. I did, a couple times during a severe drought, water a couple of old trees. But if the grass can't survive without me, then it doesn't deserve to. It's grass.

Watching for the first time in 2019, didnt know Hank was always this awesome!
