3、物多样性重要吗？科学家们为直接或间接保护生物多样性提供了一些具体的、切实的理由，支持人类社会的长期可持续性。此外，除了给人类带来实实在在的利益外，许多人认为生物多样性保护还有伦理和美学的维度。第二节 Valuable EcosystemHealthy forests can provide clean air and prevent against flood and drought.Native crops can provide against disease and drought.Abundant wildlife can attract tourists and boost econ

They use field data, lab data, theory and experiments to study the impact of humans on other organisms.第四节保护生物学它是一门科学学科，致力于理解影响生态系统内和生态系统之间生物多样性丧失、保护和恢复的因素、力量和过程。这个概念是为了应对物种灭绝率的增加而产生的。保护生物学家试图将对进化和灭绝的理解与生态学和环境系统的动态本质相结合。他们利用野外数据、实验室数据、理论和实验研究人类对其他生物的影响。第五节 Endangered Sp

12、matic benefits are such that human society could not function without them. As a result, many conservation biologists and others are rising to the challenge of conducting science aimed at saving endangered species, preserving their habitats, restoring populations, and keeping natural ecosystems intact. The innovative strategies of these scientist hold promise to slow the erosion of biod
