Biodiversity and Ecosystem Services

Mr. Anderson discusses ecosystem diversity, emphasizing its role in providing essential ecosystem services. He explains biodiversity measurement through species, genetic, and ecosystem diversity. Speciation and extinction processes are detailed, highlighting evolution's role. The video underscores the importance of ecosystem services, such as supporting, provisioning, regulating, and cultural services, and the impact of human activities on biodiversity, urging conservation efforts.
