Wow, 39 is much shorter than I expected.

I guess it makes sense, because how else could you keep up with demand, but my view of animal lifecycles only has stuff like bugs fully maturing so quickly.

Interesting stuff.

Now my question is why are bananas so cheap? They come all the way from like Brazil, but they're still cheaper than the apple that is grown just a couple hours from me.



Regarding bananas, I would recommend taking a look at the history of the United Fruit Company: https://en.wikipedia.org/wiki/United_Fruit_Company

It's really a fascinating but tragic history of the exploitation of "banana republics" where banana exports become so profitable that a US-based company owned more land in some Central American countries than anyone else. They had (have?) huge fleets of ships solely for the purpose of bringing bananas into the US.

It is quite a long and complicated story, and there are more than a few books written about it.


The book The Fish That Ate the Whale was a pretty good read about all that. https://www.amazon.com/dp/1250033314/ref=cm_sw_r_sms_awdb_t1...


Bananas are very easy & cheap to transport which led to them becoming a more popular fruit, accelerating demand and supply, etc, etc.

They can be delivered while they are green and sturdy and then they are kept in ethylene atmosphere which makes them ripe so they can be instantly sold to the consumers.


Bananas in the U.S. come from Guatemala, Ecuador, Costa Rica, Colombia, and a few others, but not from Brazil. As for global production, India, China and the Philippines account for almost half of the world's production. The majority of Brazil's production remains in the country.


Bulk transport is amazingly cheap.

Those bananas are transported from the tree to a hub, from the hub to another, and from the second hub to your shop. The price of transport is almost independent of the distance involved in the middle step.


Terrible pay and work conditions for the people who work the fields and huge economies of scale.

That can be said about a lot of products, but bananas are still cheaper..


With an impending disease that is wiping out Cavendish (the most popular kind of banana), they may not be cheap for long!

The same reason a T-shirt made and shipped from China is cheaper than one manufactured next door to you.

The contribution of international transport to the cost of pretty much any consumer good is minuscule compared to other factors, so the starting premise that something should be cheaper just because it's grown locally is false from the outset.


One thing that's very informative is to look at the HP per ton of various modes of transport.

Emma Mærsk: 156,907 DWT, 150000 HP total, or about 1HP per ton fully loaded.

With the engines running full tilt she'll make 29.3 mph.

Compare with a truck that weighs 20 tons with 400 hp, so 20 hp per ton.

100 miles by truck == 2000 miles by ship.


I'd imagine it's the cost of paying migrant labor to sweep a field in Brazil vs an hour away from you.


Bananas are dependent on a chemical (ethylene or acetylene) in the air around them to ripen.

If you keep bananas in an acetylene/ethylene-free environment, they stay green.

Green bananas are quite hard and sturdy, which makes transporting them easy and cheap.

When the time comes to sell the bananas, you just need to provide them with acetylene and they will turn yellow and pliable in about 12 hours.


Here is an excelent video explaning why bananas are so cheap. Mainly because Container Ships https://www.youtube.com/watch?v=DY9VE3i-KcM


Apples are also more expensive than oranges, which I too find strange.


Cheaper by what metric? Also, it depends on the variety. FWIW, my experience is that oranges are usually more expensive than apples, except for the few weeks that oranges are in season.
