Joe Rogan | Can You Bring Back Extinct Animals?

now what do you think about these guys that are talking about bringing animals back um like as a scientist sure the extinction is it's a weird word it is it has its reintroduction is that they call it the extinction so that's what they call it yeah the extinction is to me it's fascinating especially if it's something like say the passenger pigeon right we used to have billions of them in the United States wiped them out and now they're saying you know they can take the closest living relative isolate some genes and make a new passenger pigeon is that worth it because it's something we wiped out in the last hundred years yes I feel like that's we should heal the ecosystem by putting that back right that being said we still need to learn from our mistakes like we need to take into account what we did and why we did it and like do I think there should be a Jurassic Park and a bunch of mammoths and t-rex is absolutely not that's a waste whether we can or cannot do it to me that's a waste of scientific resources that could go towards conserving things that are on the brink now when you say like heal or mend the environment or the ecosystem when you would bring back something like a passenger pigeon isn't like 90% of everything that ever existed extinct sure absolutely so does the ecosystem adjust and evolve and would reintroducing something like a passenger pigeon would it kind of [ __ ] things up that exists now where new animals have taken a different position on the hierarchy it's too short in evolutionary time so we are in what's called the sixth mass extinction event right there's been five others before us the one we're in now it's happening at 80% greater rate than it's ever happened before so we are wiping out things more quickly than the world can adapt so you know you go into an environment and you take out all the apex predators the prey explodes the prey explodes the grass gets eaten down everything collapses now if you left that environment overtime a revolutionary time it would adapt right maybe say say all of the Predators got a disease and they died out died out over 300 generations during that time something would evolve within the environment to adapt the prey so that it didn't wipe out the environment that's just kind of the nature but when you go in there and do it in ten years or five years it throws off the equilibrium so when you in theory when you reintroduce something that's been and it's not theory it's it's science they've shown this even right here in the California Channel Islands when you put something back that's missing from the ecosystem it's like you're putting a piece of the puzzle back right and then you can allow it to do its thing over evolutionary time what did they do in the Channel Islands so I was actually a big part of that and I loved loved the project so the California Channel Islands were settled by agriculture there were sheeps goats pigs bla bla there was everything brought over there right and so not catalina but think about the northern Channel Islands what happened was when all these animals were brought in all the farmers were there then Golden Eagles started coming over Golden Eagles came over to eat the pigs and everything else flew across the ocean yep flew across the channel started preying on pigs and everything else there was an animal on the Channel Islands called the Channel Island Fox a very gorgeous cute cuddly little Fox you can see him if you go to Santa Cruz Island there's loads of them now thanks to the work that scientists have done anyway they were like okay the Fox is being there it is oh so the Fox is being wiped out through habitat destruction through all these undulates that have been brought in so scientists got together and what undulates like cows yeah yeah domestic animals cows sheep goats etc so scientists came in and said you know the habitats getting destroyed the and that that's just the keystone there were several species that were on the decline the cows are getting the livestock is wiping out the habitat the foxes are declining what do we do well obvious answer let's remove all the livestock so we removed all the livestock right through helicopters it was a lot of pigs that were causing damage all that kind of stuff we removed it all then the Golden Eagle started preying on the Foxes because their main habitat was gone so now the foxes are under even more pressure so then we remove the Golden Eagles this is a very abridged version of what happened but now we've got the Golden Eagles also pushed out the bald eagle which are fish eaters which lived on the island so now after loads of years of removing golden eagles like relocating them removing all of the livestock now you have a healthy population of Channel Island foxes the bald eagles are back they're eating fish the whole ecosystem is back in balance had it been left the way it was what you would have found at the California Channel Islands over say 20 or 30 more years 40 or 50 more years No foxes no no bald eagles a ton of golden eagles and a ton of pigs and likely over time pigs would have exploded to the point that they Easter Island themselves right they ate up all the resources destroyed all the habitat population collapsed Golden Eagles collapse nothing left on the what do you mean by Easter Island themselves so you're familiar with Easter Island in South America I know what those statues are and all that stuff but I'm not familiar with what happened to cherylin so that Island is was an ancient civilization that was the mecca had everything off land had big trees tons of food blah blah blah blah people settled there and they said this place is incredible it sits paradisiacal and then they started cutting down the trees to fish they started eating all the mammals and what actually happened is because they were so remote the middle of the ocean nowhere near South America nowhere near anywhere else they cut down the last tree there were no more canoes there was no more food on the island and the population collapsed the island was barren it was void of trees void of life void of anything and they didn't have the canoes or anything to leave anymore because they cut down the last tree to build build a boat or make firewood and everybody there died oh [ __ ] so that that's what happens when you use up every last resource God so Wow when did this happen I couldn't couldn't tell you yes I thought it was like a mystery to like what happened to the population of Easter Island so they're pretty that's your that's the accepted that's the scientifically accepted understand and do they get this from fossils they get this from bones and as I was so they they've sort of pieced it together yep they took they take you know isotope samples and measure carbon dating and yada yada I think that the heads are still a pretty big mystery why I think certain people believe that the heads were like a nail you know calling to the gods to help save things because they were going so badly yada yada but I believe the heads are still a pretty big mystery but the actual anthropology the population to collapse is is known to be due to running out of resources how long did it go for good hole I do they have an idea of how long the population lasted I think it's all I think it's all published yeah I don't know off the top of my head but it was it was a thriving population that you know flew too close to the Sun is they said because of Easter Island small size only 63 square miles it quickly became overpopulated and serese-- sources were rapidly depleted when Europeans arrived on Easter Island between the late 1700s in the early 1800s it was reported that the moai were knocked down and the island seemed to that I say that right moai be the night knocked down and the island seemed to have been a recent war site hmm lots of lies yeah see the next one their constant warfare between the tribes a lack of surprise and resources disease invasive species and the opening of the island to foreign slave trade eventually led to Easter islands collapsed by the 1860s Wow so it didn't take long 1700 to the 1860s that was wrapped Wow it was annexed by Chile and so they've never tried to repopulate the island with trees or anything else and they're just kind of leave it alone I believe so I know you can go there and visit it and see the heads and I think there are some things there now but it's it's barren there are no trees there's no you know it's all been depleted
