繁殖力超强且缺乏天敌，北美浣熊在法国泛滥

Core Viewpoint - North American raccoons are proliferating in France, causing significant agricultural and environmental issues, leading authorities to classify them as an "invasive species" [1][3]. Group 1: Origin and Spread - North American raccoons were likely introduced to France decades ago by American soldiers stationed at NATO bases or by Germans for fur trade [3]. - The raccoons have adapted well to their new environment in France, rapidly increasing in population due to their high reproductive capacity and lack of natural predators [3]. Group 2: Impact on Local Environment - Raccoons are causing damage to crops, preying on birds and rare amphibians in nature reserves, and potentially transmitting viruses to humans [3]. - Estimates suggest there are thousands of raccoons in the Gironde department, possibly descendants of those that escaped from an "exotic farm" in the early 21st century [3]. Group 3: Challenges in Control - Local authorities have struggled to find effective methods to control the raccoon population, with the local nature conservation association noting that complete eradication is extremely difficult [3].
