Video 1 spoke about a Chinese vine called Kudzu. It was originally intended to help farmers fight soil erosion but it got out of control and replanted itself anywhere it could find soil and engulfed the South. The video also spoke about the Mongoose which was introduced to prey on rats but that backfired and instead they preyed on endangered Hawaiian bird eggs and and now there is a Mongoose and rat problem. The message in the video was "Be careful when introducing plants and animals into a new ecosystem without a good cause".
Maybe the most invasive species is MAN!
Video 2 spoke about the Austrailia Rabbit problem. Australia spends about 720 million dollars to try and control this population and have enlisted the help of rabbit trappers and have developed the "RHD" drug in addition there have been web sit like Feral.org.au which is to help pest animal management. They currently also use a system called "Rabbit Scan" that helps manage rabbits with people posting siteings, you can share info and find resources. It is a national approach to rabbit control. Who would have thought this would be a problem....
Video 3 is something we are all too familiar with, the Stink Bug. If they don't bit, don't get into your food or clothes, why do they exist? Farmers are losing crops, they are ugly and they serve no purpose. You can use dryer sheets if they help but those are not cheap and these stink bugs are big in numbers and there is not enough dryer sheets in the store to control them. Ok and the only preditor that can help is a Skunk? how does that really help when now you have double the smell. There seems to be no solution!
