"Biological diversity"是指生物多样性，即地球上不同物种和生态系统的多样性。它包括物种的多样性、生态系统的多样性以及基因的多样性。生物多样性对于地球上的生命维持和生态系统平衡至关重要。
以下是一篇关于生物多样性的英文范文：
Title: The Importance of Biological Diversity
Biological diversity is the key to life on Earth. It ensures the richness and diversity of ecosystems, providing habitats for a wide range of species to thrive. From the smallest microorganisms to the largest mammals, each species contributes to the overall biodiversity of our planet.
Biological diversity is essential for maintaining a balanced ecosystem. When one species is lost or altered, it can have a profound impact on the entire ecosystem, leading to changes in other species and their habitats. Conversely, maintaining a diverse array of species and habitats ensures that ecosystems are resilient and able to adapt to changes in their environment.
Biological diversity also plays a crucial role in maintaining genetic diversity. Genetic variation within species ensures that they are able to adapt to changing environments and new challenges. Genetic diversity also provides opportunities for new species to evolve and adapt to new environments, leading to an ongoing process of evolution and change.
However, biological diversity is under threat from human activities. The rapid expansion of human populations and the associated development projects have led to the loss of habitats and the extinction of many species. In order to safeguard biological diversity, we must adopt sustainable practices that prioritize the conservation of habitats and species, while also promoting sustainable use of natural resources.
In conclusion, biological diversity is essential for maintaining life on Earth. It ensures the richness and diversity of ecosystems and contributes to the overall health and resilience of our planet. We must prioritize the conservation of habitats and species, while also promoting sustainable use of natural resources, in order to safeguard this crucial aspect of our planet's biodiversity.
biological diversity是指生物多样性，即地球上不同种类生物的种数、生物之间的生态关系、物种遗传信息的多样性及生物体生存环境的多样性。它涉及生物物种的遗传多样性、生态系统多样性、生物栖息地的社会、经济、文化价值等。
在英文范文里，它可能会被提及在讨论环境保护、生态发展、生物学研究等相关话题时。例如，一篇关于全球变暖对生物多样性影响的英文范文可能会指出，全球变暖导致极端气候事件频发，进而影响生物多样性。又或者，一篇关于生态旅游的英文范文可能会强调其对于保护和可持续利用生物多样性的重要性。
“biological diversity”是指生物多样性，即不同物种的独特性和相互关系，以及生态系统作为整体的生命力。
在英文范文中的用法，通常会结合上下文来理解。例如，在讨论全球环境问题时，“biological diversity”可能意味着地球上生物种类的丰富性，以及这种多样性面临的威胁。在讨论生态旅游或可持续发展的可能性时，“biological diversity”可能被视为一个吸引力和潜力巨大的资源。
