Study Notes
Biodiversity Loss
- Human Impact: Human population growth, increasing consumption, and reduced resource efficiency contribute to biodiversity loss.
- Habitat Loss: Destroying or fragmenting ecosystems damages plant, soil, hydrologic, and nutrient resources, leading to biodiversity loss.
- Invasive Species: Non-native species can disrupt native ecosystems by outcompeting native species for resources and altering habitats.
- Overexploitation: Harvesting too many aquatic or terrestrial animals depletes populations and can drive species to extinction.
- Pollution: Adding harmful substances to the environment at a rate faster than it can be neutralized negatively impacts food, water, and habitat resources.
- Climate Change: Rising global temperatures disrupt ecosystems by altering temperature and rainfall patterns, damaging icy habitats, and modifying species' expectations within ecosystems.
Ecosystem Services
- Biodiversity delivers essential services such as water protection, soil formation and protection, nutrient cycling, pollution breakdown, climate stability, and recovery from unexpected events.
Biodiversity Benefits
- Biological resources: Food, medical resources, wood products, ornamental plants, breeding stocks, future resources, and genetic diversity are all dependent on biodiversity.
- Social Benefits: Research, education, monitoring, recreation, tourism, and cultural values can be enhanced through biodiversity.
Species Interdependence
- Species rely on each other for survival and cooperation, forming balanced ecosystems.
