I wonder how well would zoo animals would fare if they were able to escape?

are these megafauna now?? i don't think these regular invasive species brought over in the last couple hundred years have replaced actual megafauna that lived when humans arrived tens of thousands of years ago and also went extinct ten thousands of years ago?

Loved this! Kind of like the Future is Wild or Life After People.

Wow, this is awesome!

Australia should introduce lions or tigers to control all populations of animals

There are no benefits. Extinct animals are extinct.

So Australia needs a larger Predator. The should start a pilot project to bring in some Asiatic Lions. They naturally live in arid areas and if they work out they could really use the increased numbers and new habitat.

Australia just needs some lions now to complete the invasive species😂

One way of looking at these ferral beasties is if we really needed them for food.

Rewilding... We do that through immigration

I know reintroducing some animals like elephants and camels is something likely not to happen but it does make a nice fantasy. Great video and new sub!

You mentioned that the largest of our sloths was around 1.5 tons. In fact, the genus Eremotherium could grow to be much larger, we're talking elephant size, with adults averaging out at about 3 to 4 tons and having a bipedal stance of at least 12 ft. Truly some of the most impressive animals to ever walk this earth.

The megafauna species I think should absolutely be returned to what is now the U.S. mainland, Canada and Mexico would of course be the modern relatives of what was here 20,000 years ago: Collared Peccaries in California and the West, basically wherever the flat-headed peccary (Platygonus compressus) once roamed as physiologically they were apparently extremely similar - The Modern Caballoid Horse a.k.a Wild Horses, a form that is Native to N.A. and in much need of recovery - Tapirs from Central and South America - The Modern Llama (genus Lama) - Camels with Dromedaries being released where it is most suitable for them to thrive i.e. desert regions while the cold-adapted Bactrian be established in Canadas far north for example - American Bison by their millions restored to their historic range, including California - And last but not least, the Jaguar (Panthera onca) who could once be found across the continent from coast to coast

Also, rabbits are a major invasive species that has caused a lot of problems. They used to number as many as 600 million!

They should introduce tigers to the far northern areas as an apex predator, since that niche isn't being properly filled.

Knew about all but the binturong though i know of its existence,i mistook for an aya aye

If we can get the lynx back and no babies or dogs get got then the wolf will be an easier sell.

The australian ecosystem had 1 very impactful megafauna which is no longer ecologically functioning the same way. Homo sapiens. Using fire to open scrub, driving herds of kangaroos, raising packs of dingos, each family managing their own collection of varying ecosystems. Humans are now doing modern agriculture on land that can’t provide in the way it does in Europe or North America, and the systems which help to regulate flora and fauna are thrown out of whack.

The problem is, the dingo, which is the indigineous dog, was common place across australia. But nowadays they are exterminated so farmers dont have to deal with them. All these megafauna can’t really be good for the ecosystem if they dont have predators :(

I thought the terror bird was the largest in south America during that time. Very interesting though. Fascinating stuff.

They're reintroducing the Moo Slim species, to their detriment.

The True "Native Americans" they killed these amazing creatures and Karma killed them back when Europeans arrived.

00:01🙄🤔 "when humans arrived in America " . humans were already in America.

Very impressive, Ecology Nerd. As an admirer of birds of prey, I approve this very much. From this, there was a very of eagles that I never even heard of until now. I’m also glad that you’ve mentioned the Haast’s Eagle, even though it’s been long extinct. Next video should be all species of owls since they’re just as special as the eagles themselves. Cheers.

Wild boar is already here in ireland though its considered an invasive species as its not pure wild boar but nevertheless its here

There is no such thing as an Australian otter.

Both the Aurochs and Tarpan should be cloned to gamete level to add to as back-breeding programs as well as gamete cloning for European Bison and Iberian Ibex..

This is actually wild, as someone in Australia who studies native ecology it is insane to me, that you are trying to justify these invasive species being here and not being eradicated.

Hell build a few large watering hole's and add some Lion's Cheetahs and leopard's or Jaguar's maybe some other predator fish and Crabs and few bird predator's fight invasive never know might work

Who let the animal's out wwwooo wwwooo wwwooo

That's what they all say bro 😅😅😅😅😅

I think all the things you suggest here would be great actually. Replacing cows with rhino's would be particularly good imo. We can't get back what was there, but we can try to replicate it

Just release lions

I hope they bring the cheetah to north america one day, perhaps with some mild gene alterations to give them a more appropriate coat, likely similar to that of the cougar as that is the surmised closest living relative of the north american cheetah. I've heard it's in the works but who knows if it will go anywhere

Lion and tiger should be on the list because both there max weight (recorded) is 313 and 317 (gorged stomach of course) respectively so why put only one

Nilgai sees regularly by indian 😂

@Econerd some people's obviously had your thoughts around 100yrs ago. Government claim's no proof but leopard and cougar are here in Victoria 100%

European talks about introducing Eurasian animals to Australia, instead we should have our own native species dominate. Any non native animals would be a horrible idea. Literally the whole history of Australia’s species being introduced has always had NEGATIVE Consequences. I can see the same thing happening with all these introduced animals.

Komodo dragons and Cuban crocodiles can help destroy invasive animals. And Asian water monitors help in the fight against the cane toad.

"Oostvaardersplassen" , This literally means 'East (sea)farers puddles'. 'Oo' in Dutch is pronounced as the 'oa' in toast, not the 'ooh' as in tool.

So.... Before the First Australian Colonists got here, 50 thousand years ago, Australia was a wild life paradise. Then they got here and fucked everything up!!!!! So... Australian Aboriginals are ecological vandals!!!!!

Why would you want to make Australia even more dangerous? Don't you think we got enough problems

We have reintroduced the European Beaver in Scotland and it is contributing a great deal of positive outcomes to our environment.

The Netherlands, despite being overpopulated is transforming aswell. The return of the Wolf is the best example of this and i for one would LOVE if we decline the population dramatically (via immigration) and let nature run its course

That’s enough just bring the elephants here

no i cant the thumbnail is to fuzzy

Hello Australian here!. I'd like to say the introducing big cats would he a horrible idea! In Australian we have absolutely massive feral cats that can get bigger than the aberage human. we can't have pets like Maine coon's since if the genes of a maine coon spreads through the population of cats that would be horrible. Also, when i come to a large predator, one of the better options would be Cat but not a big cat. Cheetahs are very distantly related to big cats and domestic cats, so they would serve wonders. Or the hyena since they are used to taking down big game
