物种灭绝、森林砍伐、河流筑坝、洪水、臭氧层损耗、海洋系统恶化和许多其他变化都在加速发生。
The rate of species extinction is accelerating to dangerous levels.物种灭绝的速度不断加快,已经敲响了警钟。
There is no natural foresight, no mechanism for warning that present selfish gains are leading to species extinction - and indeed, 99 per cent of all species that have ever lived are extinct.没有自然的深谋远虑,没有什么机制会警告当前的自私收益将导致物种灭绝——事实上,99%曾经存在的物种现在都已经灭绝了。
