Human Influences On Ecosystem | IGCSE , O Level Biology pptx
This comprehensive presentation examines the profound impacts of human activities on ecosystems. It details how agricultural practices—such as the use of fertilizers, pesticides, monocultures, and intensive livestock production—can lead to reduced biodiversity, soil degradation, and increased pest resistance. The presentation also discusses habitat destruction through deforestation, resulting in soil erosion, flooding, and loss of vital ecosystems, along with issues like eutrophication from nutrient runoff and various forms of pollution that disrupt water quality. In addition, it highlights threats to wildlife from overharvesting, invasive species, and climate change, and outlines conservation strategies such as sustainable resource management, protected areas, and reforestation.
