全球入侵物种成本知多少？最新研究称过去60年间每年约350亿美元

Core Insights - The study published in the journal "Nature Ecology & Evolution" indicates that the global costs of invasive species may be significantly underestimated, with an estimated annual cost of around $35 billion over the past 60 years, comparable to the costs associated with extreme weather events caused by climate change [1][2] Group 1: Economic Impact of Invasive Species - The research is based on data from 162 invasive species, revealing that the global economic costs of specific invasive species could be as much as 1646% higher than previously thought [1] - The total estimated costs over the past 60 years are highest in Europe, amounting to approximately $1.584 trillion, followed by North America at $226 billion and Asia at $182 billion [2] Group 2: Categories of Invasive Species Costs - Invasive plants, such as water hyacinth and zebra mussels, account for the highest estimated costs over the past 60 years, totaling approximately $926.38 billion [2] - The second and third highest cost categories are arthropods at $830.29 billion and mammals at $263.35 billion, respectively [2] Group 3: Need for Management Strategies - The authors emphasize the necessity for regional management strategies and policies to mitigate the impacts of global invasive species, highlighting the importance of understanding the economic costs at a national scale [2]
