求翻译：王：海洋生态环境恶化、土地遭侵蚀以及沙化等破坏森林资源锐减也是主要原因之一，由于受自然或人为的因素而造成森林面积正在大幅度地锐减。是什么意思？

Wang: marine ecological environment deterioration, sharp decline in the land by erosion and desertification, destruction of forest resources is also one of the main reasons, because as a result forest areas affected by natural or man-made factors are dramatically reduced.
