What Are Ecosystems? Crash Course Geography #15

Damn.. This is so technical 🤯

I'm amazed at well explained 😊 I really enjoy your course ❤ thank you!

ok

1- what is an ecosystem?
Answer: A community of living organisms in an area interacting with their environment.

Didn't think I'd have to mention the Brazilian election here :))

Hey everybody! It has come to our attention that there are a few discrepancies within this episode worth acknowledging:

First, yes, you are correct. Jaguars don’t hunt gorillas and their natural habitats are on different continents. We decided to generalize our discussion to all rainforest biomes in the Thought Bubble, but that breaks reality. So sorry for the confusion!

Also, in this episode we’d like to emphasize that we’re only discussing terrestrial global biomes and their productivity - some of the patterns we draw here are not the same for aquatic biomes.

And lastly, yes, that fish tank we illustrated is too small. Please check back regularly for our goldfish’s grand escape! -brandon

That dress is awesome!

Thank you!!!! Agroforestry for the win 🙌🏼

Please don't present a water bowl as an acceptable living space for a goldfish. This is an educational channel, it's a shame to perpetuate misconceptions leading to aminal cruelty.

I love this series!

I like her ear rings.

Im getting real Ms. Frizzle, magic school bus vibes and I love it lol

How did the jaguar get to Africa so quickly - or was the gorilla already waiting for it in South America? ;) Seriously, great video, as always! :)

Even if you have the most sustainable way of growing food, humans will reach the limit and go over it with population. Only human depopulation can save the world.

Fantastic episode!!

Great explanation! I just wanted to add that this size fish tank is only appropriate as a thought experiment, but not for keeping fish in real life! Please if you want fish as pets keep them in a big enough aquarium with other fish, plants and enough space to swim around :) thank you

I love you and crashcourse your are the best teachers in the world. I love geography too. Thanks for sharing your knowledge.

Amazing video!

I always knew about how critical a balanced ecosystem is but what your comparison of shifting cultivation with mass cultivations was so interesting. We are essentially sucking the nutrients dry from our most precious resources

A jaguar (panthera onca) eating a gorilla is a strange example... as Jaguars lives in the American continent and gorillas on Africa... maybe a leopard (panthera pardo)🐆 would hunt a gorilla? ;)

Thank you for all the info...! This is very helpful.. :D

What is your opinion on vertical farming locally which uses organic means with A.I, optic and humidity modifications?

👌👍

Hi...crash course...pls plug in the subtitle of Chinese or mandarin. I love ur video so much but mostly I hard to understand. Thanks

Thank you!! This is a very informative video

A) awesome shirt
B) awesome video
C) jaguars hunt gorillas? I thought jaguars were exclusive to the Americas and gorillas to Africa

Aliens delivering us gas? or are they farting at us??!!

It was truly delightful to learn about nutrient cycles, biomes, and the geobiosphere—especially that the quantity of nutrients is capped but can be sustained by clever farming and land use.

Educational!

These are so good. If only Crash Course makes courses on biochemistry and microbiology.

Jaguars eating gorillas?

Did you transport a poor innocent gorilla to the amazon? Or did you confuse jaguars with leopards, the other big cat with spots that lives in Africa and Asia?

Or maybe it's an abstract rainforest, with animals from everywhere?

*what were ecosystems before humans existed

crash course is so amazing tbh. the footages are always so diverse and show a lot of representation, and they also never fail to mention indigenous people's rights in according topics like in this one and the linguistics series. so grateful for crash course's works! ❤

I really enjoy how this course makes the information fun, accessible, and still feels like it's teaching me something new and important each time.

Ah yes, another excellently informative video.

Is this video saying Slash-and-burn, is an ok thing?

Please never keep any fish in a bowl that small

Man, I was taught that Slash-and-Burn agriculture was a lot less sustainable and thought out. Though, that might be because land rotation was left out in my instruction on the matter.

👍👍👍👍👍

As a 28 year old adult, I find these videos both endlessly fascinating and incredibly resourceful....and to think I knew all this stuff when I was a kid...

I hope my school teachers were half as good explaining these topics in class

Putting the onus of enviromental protection on people instead of corporations and States (as in "you have to find out where your meal is produced before eating it) is unfair and makes no sense regarding the actual means of each part to do harm and change.

THANK YOU, this is awesome

Such a humongous intelligent behind our creations.

Screwed up how humans tear down forests to get more land and make more money...

hope yall are safe in your homes :)))
