砍伐

PA-457 was not just another Taxol, the anticancer drug that required the controersial felling of rare yew trees until a semisynthetic substitute was found. Panacos did not need a steady source of Taiwanese herbs. Betulinic acid could be extracted from ubiquitous plane and birch trees, and a subsequent processing step yielded the desired molecule.

PA-457不像抗癌药物太平洋紫杉醇：在太平洋紫杉醇的合成代替品出现前，砍伐罕见的太平洋紫杉一直引发争议；Panacos并不需要有稳定供应的台湾药草，桦木酸能从普遍存在的悬铃树和桦树中提炼，并且只要一个后续处理步骤，就可以制造出所需的分子。

However, as a result of human activity especially moorland is reclaimed, the aggravate that uses favourable geographical position waiting for earth of chemical fertilizer to use an activity in great quantities, and large-scale disafforest and habitat are broken the change that spends favourable geographical position waiting for earth to use structure, played havoc with natural landscape, the change moves floral to live environment, make ecosystem function degrades, brought about the forfeiture of biology diversity finally.

然而，由于人类活动尤其是荒地开垦、化肥的大量使用等土地利用活动的加剧，以及大规模砍伐森林和栖息地破碎化等土地利用格局的改变，严重破坏了自然景观，改变动植物的生存环境，使生态系统功能退化，并最终导致了生物多样性的丧失。

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

其中，形成于第四纪河湖相沉积沙的疏松土壤母质，为日后土壤风蚀奠定了深厚的物质基础；干旱多风的气候条件构成了草地风蚀沙化的自然营运力；而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。

So unless the world can eliminate emissions from all other sources--cars, power plants, factories, even flatulent cows--it needs to reduce deforestation or risk an environmental catastrophe.

因此除非世界能消除其他诸如汽车、发电厂、工厂、甚至是食量巨大的乳牛所致的碳的排放，否则，就应当减少森林砍伐，不然将导致一场环境灾难。

The intensely lovely little Jiuzhaigou complex of chromatic lakes in glacially awled mini--valleys is already nearly bereft of the tubby black-and-white pandas that once thrived here—an animal now trumpeted by the government as "our national treasure" but displaced wholesale by heedless logging and a die-off of bamboo during the last decades of the past century; more than one Tibetan described the decimation to me.

冰川期形成的小峡谷中星罗棋布的分布着众多色彩缤纷的湖泊，这里最受喜爱的标志是几近绝迹的胖乎乎可爱的大熊猫，这里曾经数量众多。大熊猫现在被政府宣传为&我们的国宝&，但上世纪九十年代却对砍伐竹林和任由竹林死去不管不顾；不止一个藏人对我描述过大规模的毁林。
