global transport has facilitated the spread of organisms across the planet. The

potential danger of this aspect of globalization is starkly illustrated through

the spread of human diseases like HIV AIDS, mad cow disease, bird flu and

swine flu, but invasive plants and animals are also having a devastating

impact on native biodiversity. Non-indigenous organisms can quickly occupy

disturbed land and natural areas where, in the absence of their natural

predators, they are able to thrive. At the global scale this issue is being

addressed through the Global Invasive Species Information Network but

there is improved international biosecurity legislation to minimize the

transmission of pathogens and invasive organisms. Also, through CITES

legislation there is control the trade in rare and threatened species.

Increasingly at the local level public awareness programs are alerting

communities, gardeners, the nursery industry, collectors, and the pet and

aquarium industries, to the harmful effects of potentially invasive species.
