Study Notes

Biodiversity: The Tapestry of Life

  • Biodiversity refers to the variety of life on Earth, encompassing plant, animal, fungi, and microorganism species, and their inhabiting ecosystems.
  • Intended learning outcomes include discussing biodiversity benefits and determining everyday tasks' contributions to biodiversity and societal well-being.
  • Biodiversity depends on factors like temperature, precipitation, altitude, soils, geography, and other species.
  • Levels of biodiversity include species diversity (variety of species within a region or ecosystem), genetic diversity (variation of genes within a species), and ecosystem diversity (variety of ecosystems within a region or the planet).
  • A species is a group of organisms capable of interbreeding and producing fertile offspring.
  • Species diversity describes the number of different kinds of organisms within ecosystems.
  • Genetic diversity is the variety of genetic information in plants, animals, and microorganisms. It's the raw material for microevolution and environmental adaptation.
  • Loss of local populations decreases genetic resources and threatens species survival.
  • Ecosystem diversity encompasses biotic communities, habitats, ecological processes, habitat differences, and diverse environmental processes.
  • Grasslands, reefs, and tropical rainforests are examples of ecosystems, differing in species composition.
  • Ecosystem services include air and water purification, climate regulation, erosion control, recreation, and resources like wood, water, and food.
  • Biodiversity is crucial for a variety of economic benefits including direct economic value obtained from plants, animals, and groups as sources including food, medicine, clothing etc, and indirect economic value that arises from ecosystem services.
  • Ethical and aesthetic value means that species, regardless of use, have an inherent right to exist; inspiring biodiversity preservation for their own benefit.
  • Biodiversity conservation aims to preserve biological diversity, prevent species extinction, maintain ecosystem characteristics, avoid unplanned developments that damage ecosystems, carry out careful scientific exploitation of natural resources, maintain essential ecological procedures, ensure the preservation of aesthetic and recreational aspects, and ensure valuable natural resources for the future generations.
  • Conservation efforts include establishing protected areas, restoring habitats, managing species, and protecting endangered species through captive breeding programs, habitat conservation, and anti-poaching efforts.
  • The future of biodiversity necessitates ongoing conservation efforts for sustainable futures of a thriving biosphere.
  • A key point regarding the biodiversity crisis from human activities (such as habitat alteration, introduction of invasive species, increased population growth, pollution, over-exploitation) and climate change.
  • The acronym HIPPO (Habitat destruction, Invasive species, Pollution, Population, Overharvesting) summarizes the key threats to biodiversity.
  • Reasons for the biodiversity crisis include the country's development objectives (road networks, irrigation, power and energy projects).
  • Aimed at protection, upliftment, and scientific management of biodiversity, to maintain its threshold level and derive sustainable benefits.
