Just a piece from an email that I received today regarding invasive species. Makes you think.
Hi Ruan
Comment by Alan Urban of PPRI on LinkedIn Insects and Entomology group re strict new pet-keeping laws about to be promulgated in West Virginia US. I like the Russian Roulette comment! But anyway this is why I am so very anxious about the general public and exotic pets, which I know you know. So few people understand this point of view.
The broad view is that, second only to habitat destruction, invasive alien species, be they plants, invertebrates or vertebrates, are the most important factor reducing aquatic and terrestrial biodiversity and ecosystem stability and services worldwide. Some individuals in these non-native plant and animal populations always escape, or are abandoned, or are transported and released into the wild, where a small percentage of alien species become naturalized and invasive and wreak enormous damage to indigenous ecosystems. Numerous invasive alien species such as yellow starthistle, kudzu vine, green tree snake and Burmese python have damaged various parts of American ecosystems very seriously.
We're not against them because they're alien, but because they're potentially invasive, and therefore potentially ecologically damaging. Exotics may be attractive and interesting to possess, but one is playing Russian roulette with whole, invaluable, indigenous ecosystems. And most invasive alien species are impossible to eradicate, so the damage is cumulative and permanent. The ecologically responsible thing to do, is to prohibit/refrain from the importation/aquisition, propagation/breeding, transport and release of all non-native species that have the potential to become invasive, and to harm indigenous species, somewhere on one's land-mass or territorial waters.
Tsk, I also know you know that I know you are a responsible pet keeper, but what if you fell under a bus? What would happen to you ornamentals?
Cheers
