但是这份报告哀叹道：当前有数不胜数的交易及收获中的野生产品严重缺乏监督，结果导致生物栖息地退化，物种资源衰竭。

But the report laments that far too much of the harvesting of, and trade in, wild products is poorly supervised, with the result that habitats are degraded and stocks depleted.

数值效应是明显的：退化地区的鲑鱼数量比原始地区少；然而，栖息地的丧失也有可能减少遗传多样性。

The numerical effect is obvious: there are fewer salmon in degraded regions than in pristine ones; however, habitat loss also has the potential to reduce genetic diversity.

由于栖息地的丧失或退化，外来物种、气候变化、过度采伐、环境污染以及野生物疾病的影响，各类物种正在受到威胁。

Species are being threatened by habitat loss and degradation, invasive species, climate change, over-exploitation, pollution and wildlife disease.
