Ecosystem Diversity

Mr. Anderson discusses ecosystem diversity, emphasizing its crucial role in providing ecosystem services that support human life. He explains how biodiversity is measured through species, genetic, and ecosystem diversity. The video covers speciation and extinction processes, highlighting evolution by natural selection. It also addresses human impact on biodiversity, suggesting we are nearing a sixth mass extinction. The importance of ecosystem services, such as supporting, provisioning, regulating, and cultural services, is underscored, with a call to protect biodiversity for both ethical and economic reasons.
