"It was fun at first, and then it was not!" -Hank Green

I don't know what university you are going to, but mine is like being able to watch 2 full hours of Crash Course a week for 5 different subjects.The profs are interesting and engaged, the topics are interesting... any school that fails at that is robbing you

Can you please please please make Environmental Science videos for the AP Environmental Classes

No

that process of the oxygen being depleted after a rush of nutrients and algae bloom is called eutrophication, and I was slightly disappointed that you didn't include this marvelous word. But kudos for all the education you are doing and I hope you will continue and create graduate studies after this!!

And also the Biochemical Oxygen Demand (B.O.D). The amount of oxygen required or in demand of by the ecosystem, when eutrophication occurs, B.O.D levels increase as the amount of oxygen depletes, thus pollution or quality of water can also be measured by an ecosystem's B.O.D levels.

Since it seems like John always covers things that humans do, and Hank always covers what nature does, it's so nice for Hank to cover humanity's achievements for once.

do more "our effect on the planet" type of videos

Writing to thank you very much for your videos. I use them a lot in my classes here in Brasil, even with the language barrier, they help a lot. I have use them as a review before my classes in the post-graduation course where I teach ecology.

I would have liked to see a vid on pros and cons of the variety of energy production we have. Geothermal, Solar, Hydro, Nuclear, Treadmills... Each one has pros and cons and people don't really know what methods can and can't be used where in relation to needs and resources. I wish more gyms used there treadmills and bikes to power the place though, as just a side thought.

My lazy professor linked our class to this video as well as other videos.

How I wish Crashcourse will make videos about Agriculture

Very, very, and very wonderful presentation. Precise, satisfactory and brief to the point. The presenter talk strait forward hammering out points on the subject. The presenter exactly talked like our lord Jesus Christ on mount Zion. God bless you my son to help people understand the phenomenon we faced unknowingly in this world. God bless you and your team. Emmanuel Kuol.

I can't thumbs up enough for this one.

Hey there. Just wanted to say that as a Freshman undergrad aspiring to be a Chem/life science student, Hank's one of my geeky role models. I love his videos and think he kicks major butt

could you make a vid on DDT's?

It's really lucky when there's a crash course video on what you're learning in school. I

As to what you could actually do: generally only buy that which you need. More specifically: buy organic food (against Nitrogen, Phosphorus and pesticides), use as little energy as possible or "green energies" (e.g. no car, renewable energies for electricity, don't heat with oil, efficient household machines/light bulbs, buy local foods, etc.), don't buy gold, eat little meat (reduces methane, fertilizers and pesticides). But that only avoids the natural compounds :S

Please, please create world geography videos!

Thank you Hank, for scaring the crap out of me.

Many of the 'pollutants' occur in nature and are nutrition to the ecosystem as Hank says. However, they become pollutants when they exceed their nutritious value and start to harm the environment. eg. humans need phosphorus to grow right, but if too much gets into our drinking water due to run-off from fertiliser etc it can harm human health dramatically. I guess it is about finding a balance, but nature is pretty good at doing that without our help.

This video needs way more views because this is super, super important.

you should do one on microplastics and oxybenzone. Anthropogenic imapcts to our oceans

okay so basically i've watched all the other videos abd i've got one video left to finish cc ecology and the last one's called conservation and restoration all i can say is bro, there's nothing we can do at this point. hunams messed up. there's not restart button but i'm sure we'd do it dumb the next time around as well. @humans pls stop in the name of all things earthly

Hank (And also all of sci-show and crash course, and John), please do an "education" tour. Go to different schools, and just make people aware of these resources. I want to see them being used more, and I want to see more people being able to knowledgeably engage the problems before us. My entire generation has been told over and over that it's up to us to save the planet, but most of us don't know how to do that, or where to go to start learning. This is a good starting place. Help us, Hank.

And now that you know, you can start doing something about it! At the simplest level, make it part of your voting intentions (and let your politician know), or do more and volunteer for a conservation or advocacy group.

Love this series, but the sound effects of the pop-ups are distracting.

Thank you for helping me with my law studies "group" project which I am currently doing all by myself bc no one of my age really cares about law studies but me.

Your timing with this video was impeccable

We're really fortunate to live in the golden age of post-industrialized Earth. We're still reaping all the benefits of destroying our planet for economic gain without suffering what will be catastrophic problems as a result. At least in the developed world.

Oh, men, you talk to fast :D however, is really helpful this channel and on top of what I learn from you guys I improve my English. so keep doing what you do because you are amazing and thank you!

I love the new background! Please keep it as it helps me from not going blind. Great show, please keep them coming :)

I'd like a video telling the viewer what life-style changes they can make to lessen their impact on the environment.

Impractical. We require fossil fuels to power our transport and that accounts for the majority of our sulphur and nitrogen dioxide.

Also the release of sulfur dioxide, nitrogen dioxide, and carbon monoxide are primary pollutants. After it reacts with some other element like water of oxygen in the air, usually cause by the sun, the out come is a secondary pollutant such as sulfur oxides( SO2 and SO3) that eventually enter the rain and become acid rain.

Don't forget that increasing carbon dioxide concentration in the air also increases its concentration in the ocean, which in turn increases the ocean's acidity.

The truth is, very little. The percentage of waste produced by normal people is negligible when compared to the kind of stuff corporations do, like Hank was talking about. Most of this "going green" thing that's become popular is, unfortunately, mostly psychological, and has little lasting effect on the environment. The key is to get corporations to stop polluting.

Hope this helps for my AP Test tomorrow

Biology and ecology have been awesome, Hank, I've learned more and had more fun than in any biology class I took in high school or college. Looking forward to the last episode and to whatever subject comes next.

This video highlights something I have been saying for a while. We have no proof of man causing global warming and that all anyone focuses on but there are some many more problems that we definitely did cause and we should be trying harder to solve them.

please do physics and/or chemistry videos!! please!!

If you have bath and body works antibacterial stuff, you might want to look at the active ingredients because some of it uses triclosan, which can disrupt the endocrine system

Except plastic litter is a huge problem. It never decomposes. For instance, birds eat it it and never pass it. It accumulates in their stomachs and they die, either from starvation or ruptured guts. Then of course all there's all the other animals that are affected.

This was very interesting. I never thought about all the different substances we pollute the planet with. The media tends to only ever talk about carbon dioxide.

Yaaaaay! A video on dead zones!

I'm Japanese and I use this video for studying English Thank you for uploading this video

industrialized farming. referring back to the basics for better insight isn't such a bad thing. sensible stewardship has nothing to do with banging rocks and sticks together, but humanity's 'proliferation' is also a large part of the problem. there has to be a balance found to sustain our species for the long term, and to do that humanity needs to start living within it's means, environmentally. egotism is the reason we have such an impact, intelligence is trying to limit the damage.

One documentary everyone needs to see is "Gasland".

You can also use mercury, which is a huge problem in the amazon river basin

Aaaaa thank you so much! I got an exam on this (and other) stuff this Thursday and this helps a lot!

I'm glad that you're gonna get to some solutions, I get irritated when people complain about how awful things our but don't contribute to finding solutions.

plants, animals, and the ocean: were all good on carbon Hank: It cant just go back into the rock... Me: WHAT IF IT COULD?!

can you talk about biochar and how its carbon negative? i think its very important in regards to ecology because char is a natural thing that fires do. also its the only carbon negative solution we have.

I don't think it matters when you live, the earth is still there and you can still harm it. In my day we were poisoning the air with all our blacksmiths and garbage and sewage. So seriously, care for your world.

If you did a Great Minds episode on Carl Sagan, his fans would thank you billions and billions of times!

What? only 12 episodes of Ecology? I just assumed ~40 was the Crash Course standard. but seriously, some kind of Neuroscience / Neurology class would be awesome.

Thank you for this video. It was very helpful. I just watched the ecology #10 and as soon as I heard about this video witch helped a lot. Thank you very very much!

Or we could invest in sustainable resources, such as solar, wind and geothermal energy. We can keep our energy addiction, but only if we are willing to pay the cost to receive that energy sustainably. I do not know a single person who is suggesting that we go back to horses, or that we stop using refrigeration. The people like Hank and I want energy to be drawn using sustainable resources that we already have access too. It's a short term loss, long term gain scenario.

Its amazing, I can't help but wonder if we'll ever be able to make something as crazy and beautiful and awesome as the environment synthetically.

We want a Crashcourse Physics !

I love your location shooting Hank. I'm sure its more trouble, but worth it! Beautiful vid, for such an ugly topic.

Toxic metals like mercury also play a big role in autoimmune diseases. Autoimmune diseases are growing at an alarming rate. One of them is cAlled type 1 diabetes(different from the more common type2). To find out more on type one diabetes check out type1vlog. Good video too

Hank for President!

Very well put together and explained brilliantly

I can believe you when it comes to pollution, because you use facts instead of drama

Great work! There's a difference between pollution and contamination.

Most of the processes we have to scrub crap out of our atmosphere, is dependent on some rather rare materials, or common materials which inflict lots of pollution in the process of producing them.

Dammit, John was right all the way back on Crash Course World History Ep 1. This is all a result of our choice in Agriculture (especially pollution).

Could we fix the dead zone by putting an enormous bubble curtain in the Mississippi and hyper-oxygenating the water before it flows into the ocean?

This will video always my group

BPA is also abundant in receipts and other heat sensitive papers. just a heads up...

Probably, if two things happened. If that process became economical, one. Two, if a majority of people really cared about it. Unfortunately I doubt either of those things will happen soon.

Contact your legislators! Let them know how you feel on environmental issues. Ultimately, it's only through legislation that restricts pollution that we're going to see a huge decrease in it.

"Learning has a name, and the name that is has, besides learning, is Hank." -The Mayor

When fertilizers are cheap it costs less to use too much of them than it does to monitor the amount needed. Specially since the amount needed in a field varies from one square meter to the next depending on the soil. There are technologies now that allow farmers to monitor there fields with satellites and then use gps guided smart tractors to precisely spray where its needed but, as you can imagine, that dont come cheap. Even then it can still be washed out by rain before the plants can use it.

@MrRizeAG individuals can change corporations through supply and demand, though. It's a very slow process, true, but it's lasting when consumer habits change.

Crash Course Ecology winds up to be quite short. I like the ride but I'd also like a more detailed look. Either way, I'll be sure to also like what comes after.

could you do a video of every way that rain is made by waste products in gases and every other mass industrial waste that influence rain in anyway because it is illegal to make rain in Australia but I wanna know how many companies/industry's unknowingly or knowingly do it

If this is over next week, what are we learning next?

CrashCourse is fantastic.

I'm really looking forward to the next few weeks of CC ecology, because shit is scary so far. Enlightening. But scary.

I agree, it really interrupts my concentration on what he's saying.

From the sounds of it, what we can do about it is the next lesson.
