Conservation and Restoration Ecology: Crash Course Ecology #12

Hank wraps up Crash Course Ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the moves we've learned about in the past eleven weeks, and applies them to protecting ecosystems and to cleaning up the messes that we've already made.

Hey there! I'm a chemical engineer doing a PhD to try to move into environmental engineering, so I've had to try to very quickly catch up on a lot of biology and ecology knowledge that I was missing. I've just finished going through the whole biology/ecology series, and it was really helpful. Thanks Hank and friends!

[@PixelCortex]

"let's try to uncook this unbelievably large pile of bacon we've made" Frikken best analogy I've ever heard!

[@FuzzyPanda962]

I really like what you do with this channel, you explain biology concepts at a comfortable level of depth but in an easy way and its making my 200's biology class a lot easier to understand. I also really enjoy your balanced approach to ecology topics especially restoration ecology which tends to be either praised or condemned making good information tricky to find. Thank you

[@Nothing-bl7bj]

Great course! This really raised my awareness not only on ecology but life in general. Thanks a lot guys

[@MsKillersexy]

i have my IB ESS exam tomorrow and you have no idea how much this helped me. you're a great teacher and so passionate about the subjects you talk about. please keep up the good work!

[@emstar780]

yeah i did conservation biology work with an endangered population of seals in greece. honestly, it's such a rewarding field. There are so many aspects to conservation biology; there's the genetics, the history, and the ecology. it's a very underrated topic that not many people know about so it's great that it's been covered on crash course!

[@Fenrisson]

I can never have enough Crash Course.

[@karenlee473]

just watched the entire ecology playlist to study for my ap environmental sci exam tomorrow LOL i think it helped..a bit. better than nothing :)

[@josephledbetter9915]

Man that was really informative thank you to everyone who helped write direct and film this you guy s are great and what your doing to to teach us and help us learn is even greater. Keep up the good work and I’ll keep watching and trying to get more people to watch as well!!!!

[@queergeologist8207]

4:38 I've actually seen a live black-footed ferret, in 4th grade we had a unit on Colorado wildlife and a guest speaker came in with a large tank that had a black-footed ferret.

[@snakes9110]

Hank, It would be great if there were audio podcasts of these. Then I could listen to these while driving, running, cleaning my room, and other activities that involve using your eyes. P.S. You guys are better than Khan Acadamy :)

[@tony39802]

You can make them yourself from current videos

[@milowhynott5002]

[@radat6711]

crash course is on khan acadamy

[@patterson2.2]

IT's ironic that khan academy presented this...

[@rohwaneros]

Can't you all just appreciate the fact that both of these platforms are offering us free education? There are children who struggle to feed themselves, get proper access to education, and access hygiene. Where I'm from, our education system ranks 3rd worst in Asia and it has been in the top 10 worst education quality list for years - you can't imagine how exhilarated I was to discover these platforms. I don't mean to offend anyone, but I'm just suggesting you all be appreciative of the work that these platforms put into ensuring free high-quality education for children of all backgrounds.

[@fluffmcmuff6801]

Thank you for educating people about this important science. We're as healthy as our environment & must treat it with respect. Water's worth more than money.

[@joshn2564]

Thank you for presenting your ideas and theories to all & encouraging debate/conversation about each topic.

[@ritalennon4596]

I was lucky enough to call Missoula my home from 2006-2012. I clearly remember them digging up this location. I've been watching Crash Course for several years, recommending it to my students and posting your Biology videos in my pharmacology course. Gotta say, I've been a huge fan, and now I'm an even bigger fan. (Go Griz)

[@laurabergman6674]

oh wow does that area of milltown look different now! i grew up in and around missoula, including milltown, and have lots of friends still up there, i'm glad their kids will have a clean river ecosystem to watch regrow.

[@nintendow1]

This series has really helped me in my AP Biology course, either by helping me review or introducing me to new topics and ideas. Here's to more great series to come!

[@PianoForteKitty]

I was in Butte Montana for a while. They have the Berkley pit there that had a similar situation of a copper mine closing and because the pumps were then turned off all the water that has seeped into the pit since is super contaminated. This mine, however, closed in the 1980s and they really haven't done anything about it until recently. They had just started building a treatment center before I left to help treat the water before it overflows and drains into nearby lakes and rivers.

[@izzy3945]

This series was amazing. Thank you for being such a good teacher!

[@diamaudixaudioltd.299]

watched every single episode - TWICE. The beautiful delivery is a tragic irony with the nature of the news

[@alexandrasvdavis]

This was an awesome group of videos, great AP ENVIRONMENTAL review sesh!!

[@AndersonBrosVlog]

I don't know how much you're making in the process of creating these videos but you should be making more. Thank you for doing this. I feel like it's making a better species out of all of us.

[@hannaderijke5902]

Thanks a lot for this series of crash course, I learned whole new bunch of stuff.

[@dhanma3953]

This video is awesome you explained it clearly hope you post more videos about ecological restoration!!

[@fatfrog449]

I FINISHED!!!!!!!! Wow amazing, thanks Hank for your super ecology course

[@jacobdolloso5875]

This is awesome videos! I learned a lot for this crash coarse on restoration ecological and conservation biology, thank you for this video!

[@MartinXKid]

Thank you! I love you guys so much and I've also learned so much! I probably need to listen all your videos again to completely understand everything (and maybe remember some scientific terms) but that's OK! because that's how interesting you make your crash courses! Thanks again! I owe you people a bunch!

[@leonorapaderes1062]

Ecological conservation can be brought about by Developing best management practices for sustainable resource development and land use, Monitoring and restoration techniques for wildlife, developing techniques to monitor and manage invasive species. I was thankful that i watch this video. It really helps me and the students or people to know the importance of ecology. What we should and must do in conserving and restoring our ecology. Thank you.

[@idontdoquiet22]

Really enjoyed this series. I'm sure I'll watch it again throughout next year, due to my newly declared minor in environmental science. Thanks, and keep up the good work!

[@Startzc]

These videos are awesome. They make what can be very boring reading into something more interactive and fun.

[@mishat5405]

Welp I just decided. I’m gonna go to college

[@Soysauceb4ketchup]

Here I am, 7 years later, using this video as a lecture supplement for a college lab class that just got moved online. Bless you, Hank Green

[@heatherfrank4291]

SO helpful. Very good at breaking everything down into simple terms.

[@hazamabdul2319]

this environmental playlist talks about the true happening that truely happen if we just only watch and unprotect environmental species on our ecosystem thankyou for educating about this important science were as healthy as a environment & must it with respect. water worth more than money

[@ballroomboy]

I watch for entertainment too. I love to learn and sometimes this is my source of news which I feel is better then any major TV news. Thank you and don't forget to stay awesome!

[@4mpersan]

Great series, Hank. Thanks for being so blunt about things.

[@InnocentVodalia]

How to uncook bacon: 1) Eat bacon. 2) Use energy from eating to build a farm and raise a pig. (or go boar hunting, if you're so inclined) 3) Slaughter pig to create uncooked bacon.

[@liwendiamond9223]

Warning, the following is an epic depressive internet rant. There is a TL;DR version at the bottom if you want to spare yourself the 10 minutes of reading followed by a bitter ending. Thanks. Yeah but the problem here is that it's not bacon that needs to be uncooked, it's a planet that needs to be restored. This is your analogy applied to the problem of saving the planet 1) Eat the planet 2) Use energy from eating the planet to build another planet (Or go hunt one, if we are feeling so inclined) 3) Populate new planet but this time don't mess it up too much. That is one of 3 possible solutions to fix the future and the second most reasonable. Leaving the Earth to find another suitable home that hopefully were are wise enough to preserve this time. The most reasonable solution that I sincerely hope we will implement even if it also happen to be the most boring one is trying to rebuild the planet, which would require a monumental shift in global culture. Right now, even if a lot of people are being made aware of the problem, too few are working towards a solution. For every activist ecologist out there trying to restore a given habitat or save a particular species, there are a hundred humans actively destroying habitats and species to turn a profit on the particular slice of glorious wasteful industry they built. Those are the one calling the big shots, saying X amount of forest needs to be cut down every day for this or that, and we need to harvest Y amounts of oil by the next semester to supply the increased demand. The rest of the plebeians, those without the resources and social position and mostly money required to make change happen in our society, are 90% focused on scrapping by, living out their lives as comfortably as possible and the 10% left is for helping out their immediate family and friends. The best we can do to improve the situation as individuals is teach our children and ourselves to STOP consuming excessively, STOP building new industries harmful to the world, STOP making too many babies because the planet can't sustain too many of us, etc etc. We need to make sacrifices to our lifestyles, and that's not easy, especially if too few are following the example and would rather keep their optimized capitalistic lifestyle because it's more competitive. Take for example the car. If 90% of humanity decided to stop using cars, that alone would likely save a lot of bacon from being cooked wastefully. Obviously we would want some of us to keep using vehicles to transport large amounts of goods and for emergencies, but let's face it, the car, for most people, is a convenience, not an obligation. I do not own a car, even though if I really wanted one, I could currently afford it. This has locked away some possibilities for employment and forces me to walk or use buses to go to work and back. I need to make more frequent trips to the grocery store because I can't carry as much food at once as someone with a car and any time I need to go somewhere fast, I need to either ask a lift to somebody I know who is willing or call an expensive taxi, or just accept the fact that I can't go to that place in a timely fashion. In general, not owning a car as made my life more miserable. Or perhaps I should say it's obligates a lifestyle that is less crazy fast and full of stuff. Because it takes me longer than other people to move around, I can do fewer things in a day and I need to plan ahead and focus on the things that are the most important, like sleeping, eating, hygiene and my work. I'm left with on average about 45 fewer minutes of free leisure time per day than a person with a car. That's 28.5 days per year of "time lost" walking around town or sitting in a bus, nearly 1/12th of my life is being "sacrifice" by the decision to not own a car. For practically anyone alive that I know off, that sacrifice is unacceptable, but you'd think giving 1/12th of their lives away to ensure the next generations will HAVE a life would be a decent enough deal. Plus it's not really wasted if you consider that walking an hour a day is a good exercise that's likely to keep you healthy and alive a few more years and you can always pluck some music in your ears to make it more enjoyable. It's not completely wasted. And on your day off if you decide to stay at home doing fun stuff at home you don't waste any of your time in transportation! But NOOOOOOO. Humanity in general is not willing to make the tiniest of sacrifice. Of course it's not just about personal time lost, just like an ecosystem, our lives are neatly intertwined. For instance, the fast pace of our lifestyles is a significant boost to the economy. People with more free time consume more goods, which creates more jobs, which reduces unemployment. If we take the cars out of the equation, suddenly a ton of people are out of a job, and by a ton of people I mean probably at least HALF of us. The entire car and oil industry would collapse into a speciality industry to provide only essential services for the military, hospitals, fire departments, etc etc. Lots of shops would have to reduce their stocks or close completely because when it takes you 3 hours to make a trip to the mall you tend to go there less often... it would be the greatest economic crash OF ALL TIME. Only topped by the economic crash caused by the third solution to the problem of saving the world, the simplest and least reasonable of the 3. The Ultimate Solution to Humanity Screwing Up the Planet : Get rid of humanity. Most of it anyway. About 80-90% of humanity needs to die. Horribly. This might happen regardless of popular opinion thanks to the myriads of ways in which our species is likely to kill itself of be killed by something. Global warming is likely to ultimately prevent further growth and relatively slowly reduce the global population. Growth itself will increase stress levels over the distribution of the increasing limited resources and must we not forget, we have 3 classes of super weapons available that would do a pretty great job at killing lots and lots of humans quickly : Nukes, engineered bio weapons and chemical weapons, ALL of which have been tested successfully on human populations before. (cue Nagasaki and Hiroshima getting nuked, anthrax in our mail and deployment of white phosphorous bombs. You're welcomed to google all of it for a bitter reminder that humans hate humans.) But, mother nature is also fully capable of killing us horribly. Big chunk of rocks from space, super volcanoes eruptions, random black hole from space, tsunamis, random aliens from space (You'll notice a lot of stuff from space might show up to solve all our problems, thanks space). Basically our future is grim. And likely to get grimmer and grimmer, which is why most people have already given up on the idea that things could improve. All of them would be long dead before seeing the truth fruits of a possible restoration, so what do they care? Selfish short sighted bastards. TL;DR : 3 solutions to save the world. A) Escape the world and find another one, last resort, unlikely to actually work. But could make for a nice unpredictable future. Or maybe we find the Tyranids and cry. B) Doing a 180 on what we've been doing as a species for the past 4 centuries, focusing on preservation and restoration of the natural world and letting go of many destructive habits like owning cars and wasting 50% of our food production. aka : DIE YOU CAPITALIST PIGS!!! Unlikely to happen until at least a lot of us have paid the ultimate price for somebody else's greed. C) Die. Most of us anyway. This is what happens if we can't keep our selfishness in check and apply plan A or B in time. Likely the survivors, if they are any, will experience a new dark age. Think fallout but with less awesome and mostly starving. This sucks, but sadly is also the most probable future. Sometimes I wish I would be a devoted religious person and genuinely believe that being a nice person will award me eternal paradise when this body bites it and that all will be okay. Sadly, science has made me slightly more cynical. I still try to be a nice person anyway because I love you all, even if we are heading towards a lot of pain together, and it's the fault of some greedy twats.

[@InnocentVodalia]

Wow, you read WAYYYY too far into that - I was just commenting to be facetious, since it's ridiculous to assume that a pile of bacon can fuel you enough to build a farm and raise pigs - there's too much to be done! (and the hunting *could* work, but no one knows how, except expert hunters, i.e., scientists)

[@USAltefore]

Amy Bliss I could tell you were being facetious and I got a nice chuckle out out it.

[@liwendiamond9223]

Amy Bliss Oh don't mind me. I just like to write a lot.

[@jameslong4012]

LiwenDiamond This is all true. But this is the very reasons why people gave up on doing their part to deal with the matter. If one billion people stopped doing harm to the earth, it is better than one billion people doing harms. Everyone has the ability to effects anything whether it's good or not that depends on the choices they've chosen. There is always a solution to a problem. It's just sit waiting for someone to think of it. The solution can be made to please people as well. If no one is doing something, there will be nothing to be notice and to people to follow. If you have a leader to lead people to do something good for all. Soon you will see followers coming slowly to do it too. You can make a little sacrifice for a lot of good. It will be so hard in the beginning but things do get better later on. If the solution that you came up with didn't do so good. Then keep looking for a better one. Until you have come to a solution that can do a lot of good. But never be in the mind set like what you have described. Changes is what we all never wants to do. You said that if the old ways are changed, more chaos will come. It is not true. It's just that the old will be replaced by something else. If we don't use oil we have to use the alternatives. The alternatives need man power to creates. Oil digger can become digger of Earth to create a different kind of roads for different kind of transportations system that will not harm the earth or anyone's pocket. If only people are busy thinking for good solutions, the problem would be quickly solved. Ancient human beings have tried to do monument changes but failed. But that fail lead the way for us to find better solutions.

[@afinnandfaunaproductions6557]

I love these educational channels! Thanks for this video

[@arjanbanerjee]

They worked brilliantly together during the evening of awesome so I don't think there would be a problem but yes, it would be cool to see them actually do a crash course series together!

[@tcsaile]

You are awesome for putting these short segments together. This I the kind of stuff all humans need to be aware of! I love the bacon analogy btw

[@akashlinadey1128]

Thank you for the awesome videos! Really like CrashCourse. :)

[@CatalunaLilith]

Thank you for the great lessons Hank! I'm really looking forward to the next class, whatever it is. I'm hoping for Chemistry, though.

[@applesewer2684]

Thank you CC! Another great course

[@OnlyHarleyRose]

Thanks for talking about this Hank. My university degree is conservation biology and management, so it's quite close to my heart.

[@ltericdavis2237]

I have a test on this monday. Thank you Hank! You have made studying fun!

[@errorsinconduct]

I learned the basics of all these subjects at a non-English school. Your history and ecology sections were easy to understand, but the biology section i need to revise because i have to google what everything is in my language. thanks for these videos

[@codytdwt]

Hank, these videos give my generation hope :)

[@scottp6437]

Thank you. I enjoy all you and your brother do!

passing my exam is the main reason I am watching this. also I realy like most of the videos made by Hank Green

[@Gizzm]

I absolutely love this!

[@rulerOFtheSKIES]

It's weird how well this series synced up with the A2 unit 4 biology syllabus in England. And the exam went well, so, thanks Crash Course team. Also, it was funny, so there's that too.

[@WilliamOh1021]

Hurray!!! More Crash Course!!! :D

[@Piano_Albert]

Thank you very much for this crash course on restoration ecology and conservation biology. It's a very nice summerary about alot that I needed to learn for an exam I'll have in a few days :) P.s. the math is not that difficult...

[@SweetBabyMonkeys]

My mom taught me in the kitchen that you clean as you go so that when you're done the you leave the kitchen just like you found it! Thanks Mom! =D Thank you Crash Course!

[@AndrewRedroad]

"Like un-cooking bacon" is probably the best simile I've ever heard! Even though I know you didn't write it, I hope John is proud it came from your mouth!

[@HolyGoucky]

Hooray more Crash course!! ^_^

[@ShaedeReshka]

Another interesting take on biodiversity is the not-so-well known biocultural diversity. This concept is born out of the growing awareness that human beings are PART OF natural ecosystems, and incorporates human language and culture as an important component of biodiversity. As this video mentioned, knowledge about ecosystems is paramount to protecting and restoring them. Much of that knowledge is written into languages and cultures which are disappearing, giving us something else to protect.

[@buggy65x]

When you mentioned math I smiled. I do mathematical biology research and I work on these exact problems. Once again, math is awesome.

[@167Maverick]

Can't wait for the next crash course.

[@duhhxxxiloveyou]

thanks for helping me with AP Environmental Science!!!!!!!!!!!!!!!!!!!!

[@Katiebobadie123]

I don't know if Hank talked about extremophiles in the biology series, but if he didn't, he definitely should find a place to fit them in! They're fascinating!

[@JamieMusso]

Co servation biology is the next class I have to take after regular biology. My major is environmental science.

[@sfarzanyar]

Jamie Me aslo studied bachelor of science in Natural resources with the concentration of Environmental engineering in Iran. This was one of the best decisions of my life. Specially because it was mostly consisted of environmental science courses.

[@TheBlackrose1989]

The show Extraordinary Dogs once aired an episode about a Manchester terrier named Ozzie who is one of only three dogs trained to locate cane toads. He's utilized when incoming shipping containers to Australia arrive that often have these poisonous amphibians on board. Amazing how nature can sometimes provide potential solutions for our screw-ups.

[@Nerdfighter416]

I've been trying to find a job in conservation biology and it's been hard. I was sad so I watched this video and it made me happier. :-)

[@laurijacquelineleivers3706]

any chance you CC guys would consider an Environmental Impact Assessment (EIA) vid?

[@supercj476]

Thanks for helping me pass my midterm!

[@typacsk]

Hey all, I found a series called "New Zealand Odyssey" about restoring sites there to attract/support native birds. The videos are pretty well made (no Thought Bubble animations though), but only have about 150 views each, so I figured this was as good a place as any to plug them.

[@shahmeerhussain7438]

sir u are an excellent teacher

[@yellowcat25]

[@Teuwntjuh]

Hank, I sincerely hope you would consider a crash course chemistry. Besides the learning opportunities I'd wish to see you guys at crash course goofing about with experiments. Best wishes

[@LuckySmurf]

Sometimes the most simple approach is the best approach.

[@z4k4z]

Interesting (7:49) to hear the term "leach out" used to mean "to take in". I always hear it used in the reverse, such as "chemicals leach out of waste material into the environment". I had to look this up and see it has both meanings. Confused? I was.

[@audreysimmons3399]

[@DeniableFate]

I want to see either Hank or John give a commencement speech, it doesn't even matter what college. That would be awesome!

[@michelleh9003]

You should do a series on mythology!

[@mikeypox]

Hey Hank, you got 18K views on this video. I bet that I am not the only one of your viewers within driving distance of your work. What is the chance that you could put together a face to face tour of some of your current projects in Montana? Love yours & your brother's Crash Courses, Michael from Calgary, Alberta, Canada

[@umnodirection]

yes thats what im hoping for :) thanks very much xx

[@zaw408]

Definitely great idea

[@derderrr7220]

how about trying filtering the differeing things flowing through for certain regions of a system? so theres a concentration differential

[@RaeSan_Art]

I'm not really that into ecology. I just like and understand your videos.

[@Malyra]

Yay! Hank is working on a time machine! ;)

[@chiblast100x]

Man would I love to see a good series on linguistics, anthropology, sociology or psychology. Religion, philosophy, economics and political science all have some strong necessity here in the US, and I suspect elsewhere as well, where they get under-taught prior to the collegiate level though I'm unsure of the Green brothers' background in any of these.
