This series is so good! Alize is such a delightful host! Every series you guys have made has been absolutely stellar, and I need to thank you more often. Thank you crash course!
I study a Master’s program in Geography and know all of this already but still watch every single video, bc they are nice little overviews! Super nicely made and well-researched! :)
Just a thought (they might be too simple), should the UN be the one to hire a company from somewhere to come and clean up the garbage patches? Or am I putting too much faith that they would actually WANT to get those patches cleaned?
Basically there are 2 parts to this--firstly, we have to reduce the plastic entering the oceans in the first place. We can do this by reducing our consumption, improving waste management systems and physical barriers, such as finer filtration at water treatment plants and placing mesh barriers at the outflow of rivers. Secondly we have to figure out how to get the plastic out of the water--there are really cool tech based solutions emerging for this, like the ocean cleanup project and Fionn Ferreira's microplastic extraction mechanisms. At both of these stages however there is the issue of practicality and how environmentally friendly these solutions are. They have to be efficient, effective and cheap enough to fund (as this is something that governments don't really want to invest in), but they also should do minimal harm to the ecosystems. There are worries that these solutions may impact migratory fish (nets over river outflows), or impact small animals known as zooplankton and small plants called phytoplankton (in the case of removal technologies). Most of the oceanographers I have talked to about this think that reducing plastics entering the ocean is the most important and practical step. Everyday people can do this by being responsible with our plastic waste, and reducing microplastics (such as microbeads in cosmetics and washing clothes at lower speeds/with guppy bags). It is also important to note however that about 50% of plastic entering the oceans is from boats, and nets are especially harmful, so reducing fish consumption is also beneficial in this respect. Hope this helps😊. Edit: International agreements on marine debris do exist, however often there power is limited and enforcement is low, however they are getting better
In the Northern Hemisphere, ocean gyres rotate _clockwise_, due to the Coriolis Effect. In the Northern Hemisphere, cyclones rotate _counter-clockwise_, due to- the Coriolis Effect...? I'm missing something here.
What I never understood is how the Bahamas have crystal clear ocean water while on the east coast you cant see the bottom at waist level ? Isnt everything circulated ?
Most bays (or inlets) are like that. With slow moving water areas you don't get that flushing action. Also you may get a lot mud, river runoff and human activity that contributes to cloudy water near shore.
Don't know about this specific example, but the energy of different habitats, as well as the sediment tyoe really effects how clear the ocean looks. Outflow of rivers, shipping/trawling and phytoplankton blooms can also reduce the visibility
Informative a sad, another example of how earth has such a uniquely stable environment and how it continuously recycle material to keep that stability, And humans come along to ruin that stability.
Not related to this but could you do a video about Eudaimonism? I have ethics but I think crash course makes topics like the one I mentioned make more sense.
Fascinating episode, but it was hard to not focus on the giant trash problem going on and kinda overshadows the awesome science of ocean circulation lol 😅 rip.
About who is responsible about pollution caused by container ships its easy. We know what's the proportion of ships that belong to any given country and their routes. Poor countries don't have container ships.
Is anyone else pleasantly surprised by how interesting "Crash Course: Geography" is? 💕
@Josephine Enders Not really surprised, but definitely pleased
yes!
I was not expecting it to be as diverse a topic.
@@dudadrehmer9964 indeed. I studied Geography (over History) in high school and I remember it being a broad topic.
Absolutely yes!
0:56 "I'm Alizé Carrère and this is Trash Course Geography." - The pun I wanted
Ha! Excellent
The constant references to ocean trash upsets me. I suspect this was the point, so good job.

Me: currently in my 3rd year of an oceanography degree and know all of this
Also me: ohh crash course *click*
My school days are long behind me and I know 90% of what's discussed in most of these series. Doesn't matter, I watch them anyway
I have also that reaction even though I‘m in my second Master‘s degree in Geography :)
It’s been a while since I watched a crash course episode and gosh this music is so sentimental
I can’t thank crash course enough for relating the subjects taught to issues of today. It helps contextualize why these things are so important
I just created some ocean current videos for my earth science curriculum, this is really cool to see!
I can't find them? Could you please put a link?
Glad to hear it! Hope this is helpful additional content for your ocean current material
Didnt know geography was this cool🔥🔥🔥
Such a great show! Thank you for being here every week
0:03 well this began on a bummer😭
Okay but seriously it's awesome you guys mentioned the garbage patch. The first step toward activism is awareness!
Well explained..
Love from India ❤️
Geography is awesome!!!
Even though i already know this, I like watching this. It is called “interested in a certain subject”
Geography is my fav subject at school
I seriously love crash course helps my students.
Crash Course, you are amazing!
Just a thought (they might be too simple), should the UN be the one to hire a company from somewhere to come and clean up the garbage patches? Or am I putting too much faith that they would actually WANT to get those patches cleaned?
Very much precise. I keep coming back to this video..very well explained. extending my thanks to the host.
Nifty, i was just wondering about this actually
Crash Course Geography is freaking interesting. Thanks guys! You're doing a great job. Love the teacher.
Thank you guys so much
Thank you ❤️
Love these videos🎥!! 😌😌
Fascinating
thermoclines and salinity differences
Love the matching shirt!
Awww, Crash Course, you always know what I want to know about.
This is really neat! thank you 💗💛
I feel like we're living in the dark ages because of how ridiculous it is to just throw garbage in our oceans.
So, what must be done across the globe from now on to completely get rid of all these trash patches in the oceans?

@@sharks2571 couldn't have said it better myself! Thanks for your detailed and thoughtful response
Stop using plastics.
Large barges that have on board pyrolysis plants to process the waste it collects, and run off the fuel oil it creates.
This is literally so fascinating, like omg
Would oceanography be the correct Major that relates to this stuff? So interesting!
oceanography is cool
Love it
Good to know that Pokemon: 2000 actually did teach me something about ocean currents :D
....pretty sure gyres rotate clockwise in the southern hemisphere, not counter-clockwise 6:53
In the Northern Hemisphere, ocean gyres rotate _clockwise_, due to the Coriolis Effect.
In the Northern Hemisphere, cyclones rotate _counter-clockwise_, due to- the Coriolis Effect...?
I'm missing something here.
Coast Guards of the World UNITE!
Responsibility must go to the producing company and the end user combined. They both with synergy could tackle the problem.
What I never understood is how the Bahamas have crystal clear ocean water while on the east coast you cant see the bottom at waist level ? Isnt everything circulated ?
Theres a lot of mud and debris from rivers and streams draining into the oceans. You can see this from satellite images of coastal areas.
Most bays (or inlets) are like that. With slow moving water areas you don't get that flushing action. Also you may get a lot mud, river runoff and human activity that contributes to cloudy water near shore.
Don't know about this specific example, but the energy of different habitats, as well as the sediment tyoe really effects how clear the ocean looks. Outflow of rivers, shipping/trawling and phytoplankton blooms can also reduce the visibility
I think that water temperatures and salinity also play a roll here, as well as the plant life under the water, along with the other comment here.
Coastal upwelling plays a role. Rising deeper, colder water is rich with phytoplankton and zooplankton, which make the water appear cloudy.
sometimes, I watch crashcourse just because I can- not because I'm in school
A hill of water? "Truth is stranger than fiction" has never been so right.
Just wait until you hear about tides.
RIGHTEOUS! RIGHTEOUS! 🐢

The final episode of Crash Course Philosophy dealt with this. The whole series is worth watching.
I'm not reading any comments, I just chimed in to say - How on this earth, how on this good, great globe, do flat earthers exist!!!???
Can you do a video on engineering physics
Cool video!
Fascinating episode, but it was hard to not focus on the giant trash problem going on and kinda overshadows the awesome science of ocean circulation lol 😅 rip.
It's so ubelievably sad that after so many years of awareness, plastic is still being used...
Please make crash course mathematics
just asking, when is crash course kids updating again?
Did I need this info? No. But I surely will gobble it up 😅🤦♂️
Hello 142 like thanks for this good video stop the plastic save the planet
Im rlly sorry to say this but why is the thumbnail a bit pixelated? Though i love the content and effort u guys put in!!
Im currently watching a video on currents while curling and eating curry
👍

Trash is Trash
did you ever hear the one about the rubber duck that floated around the world
Hey crash course, not every of your fans live in the us, so stop comparing sizes with US’s states, please do it with countries around the world 💕
Hi everyone 🙂🙂🙂🙂🙂 just wanted to say I'm here because of pear from annoying orange 😊😊😊😊
Wow
hello
Make mathematical videos
What a trashy episode.......
Why??
first
First
Not true bud
I turned 14 today
This isn't "geography".
"Geography" literally means "earth description", and the hydrosphere is part of that.
It is.
It literally is by definition.
Oh but it absolutely is :)

Crash course? More like trash course, amirite?
