Reasurched Argument: Invasive Species

My paper was on Invasive Species that was taking over Australia. Its kind of hard for me to decide how to go about the argument part for this essay but i think i found the right approach. The big debate that is going on with the different types of invasive species is the fact that there are many ways to deal with the problem but which way should they go about it. In the case of the cane toads, there are two ways in which they can be controlled. One way consists of the method of clubbing and freezing the toads and the other is using carbon dioxide to kill the toads. I believe that clubbing and freezing the toads to death is more painful and gruesome than to just exposing them to a chemical that will automatically kill them without the toads feeling a thing. The only problem with the method of using carbon dioxide is that there are findings in which some cane toads have actually woke up from it. I also think that using carbon dioxide will allow us to kill a wide range of cane toads as opposed to clubbing and freezing that consist of actually finding the toads and committing these grusome acts. The Cane Toad Killing Committee argues that clubbing and freezing practices physical harm to the toads and thus makes it more painful than using carbon dioxide.

The issue that is argued with the foxes is within the debate to use feralmone in bait or to just rely on the method of trapping and shooting. On this debate I will have to argue on the side of using feralmone in the fox bate although it attracts wild dogs as well. That would have to be a small sacrifice in order for us to control the foxes more effectively. The art of trapping and shooting the foxes does not do a whole lot of damage to the fox population as you would have to physically look fro the foxes and spot them out. What about the foxes who don't come out in the open? With the method of poison bate, the IA CRC expects the damages of Australia done by foxes decrease by 10%.

When it comes to the Rabbits, the debate is fairly simple when describing the issue on controlling them. Our current method for controlling them is RHD which is a disease that is currently spreading throughout the rabbit population. The problem with this controlling method is that it is currently spreading to areas of the world where it is not needed. In order to save their domestic stock, Europe and China give their rabbits a vaccine to protect them against RHD. It is also recorded that RHD may not act as a spreading disease as they hope. I argue and urge for another method to be found to be created as trapping and shooting still holds little to no effect on the rabbit population. A method that will only focus on Australia and not other parts of the world.
