当我们观察地球、其物质和生物体时，一个突出的特点是这些组成部分及其功能背后的机制的多样性。生物多样性，包括生物体的多样性，它们的基因和生物群落，是数百万年进化的迷人产物。生物多样性不是静止的，而是不断变化的。除了内在的自然原因外，地球上的生物多样性越来越受到人类干扰的挑战。关键因素包括栖息地的破坏（农业或技术发展，特别是雨林和珊瑚礁的丧失），气候变化，物种的直接迫害和灭绝（用于传统药物用途，狩猎或渔业），以及入侵物种的引入和环境污染（其中一些显然影响了我们的气候）。全球变化（土地使用和气候）和人口增长（2009年世界人口超过67亿，每年增加近8 000万）是影响全球生物多样性的最终原因。人类干预对地球多样性的确切影响可能无法实现，直到为时已晚，以拯救关键物种。[...]
When we look at Planet Earth, its material and organisms, a prominent feature is the diversity of these components and the mechanisms underlying their functions. Biodiversity, which includes the diversity of the living organisms, their genes and the biomes, is a fascinating product of millions of years of evolution. Biodiversity is not static but in continuous change. In addition to the intrinsic natural causes, the biodiversity on Earth is increasingly challenged by human interference. Among the critical factors are the destruction of habitats (by agriculture or technical development, especially loss of rain forests and coral reefs), climate change, direct persecution and extermination of species (for traditional pharmaceutical use, game hunting or in fishery), as well as the introduction of invasive species and environmental pollution (some of them apparently influencing our climate) [1]. Global changes (land-use and climate) and human population growth (with a world population of more than 6.7 billion in 2009 and an annual increase of almost 80 million) are ultimately responsible for affecting biodiversity worldwide. The exact impact of human interference on the Earth’s diversity may not be realised until it is too late to save critical species. [...]
