Biodiversity: Types and Importance

Biodiversity

• Definition: Variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole
• Types of Biodiversity:
  • Genetic diversity: variation within species
  • Species diversity: number of different species
  • Ecosystem diversity: variety of ecosystems
• Importance:
  • Maintains ecosystem services (e.g. pollination, pest control)
  • Provides food, medicine, and other resources
  • Supports climate regulation and disaster resilience
• Threats to Biodiversity:
  • Habitat destruction and fragmentation
  • Climate change
  • Overexploitation of resources
  • Pollution and invasive species

Sustainability

• Definition: Meeting the needs of the present without compromising the ability of future generations to meet their own needs
• Principles:
  • Social justice and equity
  • Economic viability
  • Environmental stewardship
• Indicators of Sustainability:
  • Environmental impact (e.g. carbon footprint, resource depletion)
  • Social well-being (e.g. poverty rates, education)
  • Economic stability (e.g. GDP, income inequality)
• Challenges:
  • Balancing economic growth with environmental protection
  • Addressing global inequality and poverty
  • Managing resources for future generations

Conservation

• Definition: Preservation and protection of natural resources, including ecosystems and species
• Types of Conservation:
  • In situ conservation: protecting ecosystems in their natural habitats
  • Ex situ conservation: protecting species or ecosystems outside their natural habitats (e.g. zoos, seed banks)
• Conservation Strategies:
  • Habitat restoration and preservation
  • Species reintroduction and breeding programs
  • Education and community engagement
• Challenges:
  • Conflicting human interests (e.g. development, agriculture)
  • Limited resources and funding
  • Addressing climate change and other global threats

Ecosystems

• Definition: Community of living and non-living components (e.g. plants, animals, soil, water) interacting in a specific environment
• Types of Ecosystems:
  • Terrestrial ecosystems (e.g. forests, grasslands)
  • Freshwater ecosystems (e.g. rivers, lakes)
  • Marine ecosystems (e.g. coral reefs, open ocean)
• Ecosystem Services:
  • Provisioning services (e.g. food, water)
  • Regulating services (e.g. climate regulation, pest control)
  • Cultural services (e.g. recreation, spiritual values)
• Threats to Ecosystems:
  • Habitat destruction and fragmentation
  • Climate change
  • Pollution and invasive species
