  • We humans love to meddle. We just get our little homosapien brains workin' and the next

  • thing you know BAM. Disaster.

  • What's up people, Trace here for DNews -- How do you feel about invasive species? Thanks

  • to humans meddling with the environment we've got nutria all over the damn place, rabbits

  • in Australia, the Kudzu vine here in the US, cane toads, nile perch, asian carp, zebra

  • mussels... We're... not awesome at this invasive species thing are we?

  • An invasive species is one that is brought to an area and outperforms the native species,

  • often pushing them out as it consumes resources and out-breeds the locals. There are so many

  • invasive species around the world that here in the US we have a National Invasive Species

  • Council and information centers from the EPA and the Department of Agriculture -- they

  • affect every aspect of natural life all over the world.

  • Before our tendency to take stuff with us natural barriers like mountains, oceans and

  • the like kept many species at bay -- no pun intended -- but now we bring them all over!

  • Burmese pythons are an invasive species in Florida. In case you never realized... their

  • name is BURMESE. As in Burma. South Asia. They were either accidentally or purposefully

  • released and now there are as many as 100,000 of these 20+ foot behemoths slithering around

  • down there in the Everglades.

  • Even doing something as simple as moving firewood can bring with it an invasive species, like

  • the Emerald Ash Borer which is native to Asia and thanks to us humanos has devastated the

  • ash population in 14 states and Canada causing $3.5 billion dollars in damage, every year!

  • How'd it get here from Asia? We're not exactly sure, but it's likely they hitched a ride

  • on an automotive parts crate shipped to Detroit.

  • So now that we know that invasive species are bad, we should like.. stop them and stuff,

  • right? So. How... [eyebrows]

  • ... Exactly. It's really really hard!

  • State and Federal agencies have spent millions attempting to contain species with a smattering

  • of success, and now we're getting ready to play this game again. In California and Florida,

  • they grow citrus fruit. It's a thing they do. But the Asian Citrus Psyllid (ACP) is

  • just reaving all over their crops. And no one likes reavers. The pest gets into their

  • trees and carries a bacterial infection that attacks the fruit causing it to shrivel up

  • and taste terrible. Kill the psyllid, save the fruit! So now the growers have imported

  • a wasp from Pakistan to do the dirty work -- the Tamarixia radiata has been released

  • periodically since 2011 and SO FAR it seems they're ONLY attacking the ACPs. Since then

  • fruit yields have improved and the University of California Riverside says the wasps have

  • only migrated about 65 miles from their release points... so far...

  • Knowing what we all know about invasive species, Is the industry pulling a 'Crazy Ivan' to

  • save their fruit trees? Could this actually work? Or are we just kidding ourselves? Tell

  • us what you think and thanks a bunch for checking out DNews today! See you next time. Bye guys!
