| 总结: | The agricultural species that form the basis of the economies of most of the
countries of the world have been largely introduced from other areas, clearly
demonstrating that importation of alien species is not inherently detrimental at
least from the human standpoint. However, many pests have been transported
around the globe as well and cause a great amount of damage. It is estimated that
the loss caused by invasive species globally is about US$1.4 1012 or 5% of the
world gross national product (Pimentel et al., 2007). Although tens of thousands
of species have invaded other lands, millions have not. Undoubtedly a great many
potentially invasive species could cause significant economic and ecological
damage to the diverse countries of the world. Phytosanitation aims to keep that
damage and the number of new invasive species as low as possible through
regulation of trade of items that could carry invasive species. But these
requirements are a primary impediment to international trade, a key and
growing component of most economies (Fig. 1.1). Mumford (2002) points out
that domestic consumers ultimately pay for quarantine restrictions in higher
prices for quarantined goods while domestic producers of those goods or, we
might add, reasonable replacements for them, benefit. |
