Biodiversity: Who cares?

Biodiversity refers to the variety of life on Earth and highlights the interdependence among living organisms. It includes three main components: genetic diversity, species diversity, and ecosystem diversity. While biodiversity is vital for providing essential resources like oxygen, food, and medicine, it is facing severe threats due to habitat destruction, pollution, climate change, and exploitation. Alarmingly, species are going extinct at a rapid rate, with estimates of up to 20,000 extinctions each year. This underscores the urgent need for conservation efforts to protect our planet's diverse life forms.

  10. Biodiversity What does “Bio” mean? Life Bio =

  11. Biodiversity What does “Diversity” mean? Diversity = Variety

  12. Scientists have identified more than 2 million species. Tens of millions -- remain unknown • The tremendous variety of life on Earth is made possible by complex interactions among all living things including microscopic species like algae and mites. Biodiversity is the variety of life on Earth and the essential interdependence of all living things

  13. There are 3 components of biodiversity • Diversity of genesChihuahuas, beagles, and rottweilers are all dogs—but they're not the same because their genes are different. Beagle Chihuahua Rottweilers

  14. There are 3 components of biodiversity Diversity of speciesFor example, monkeys, dragonflies, and meadow beauties are all different species. Golden Skimmer Meadow Beauty Saki Monkey

  15. There are 3 components of biodiversity Variety of ecosystemsPrairies, Ponds, and tropical rain forests are all ecosystems. Each one is different, with its own set of species living in it. Paines Prairie Florida Sand hill Pond Hoh Rain Forest

  23. Biodiversity has Intrinsic Value Intrinsic Value = Something that has value in and of itself

  24. Biodiversity also has utilitarian Value Utilitarian Value = the value something has as a means to another’s end. • Utilitarian values include: • Goods • Services • Information

  25. What do we get from biodiversity? Oxygen Food Clean Water Medicine Aesthetics Ideas

  26. Should we be concerned about biodiversity? What we know:The Earth is losing species at an alarming rate • Some scientists estimate that as many as 3 species per hour are going extinct and 20,000 extinctions occur each year. • when species of plants and animals go extinct, many other species are affected.
