  1. BBA Part1_1 (Gajaseni, 2001) Man and Environment Asst. Dr. Nantana Gajaseni <gnantana@chula.ac.th>

  2. What is environment? • Q. What is environment? • A. It depends! • Q. Depends on what? • A. Depends on "Environment of whom?" BBA Part1_1 (Gajaseni, 2001)

  3. Q. How about “environment of human”? • A.Wait and see! BBA Part1_1 (Gajaseni, 2001)

  4. Q. Who is "human"? • A. Wait until the next section! • Q. Is human a living object? • A. ? BBA Part1_1 (Gajaseni, 2001)

  5. The human animal BBA Part1_1 (Gajaseni, 2001)

  6. Q 1. What is living object? • Q 2. What are differences between living and non-living objects? BBA Part1_1 (Gajaseni, 2001)

  7. A. From biological perspective: • Life = biosystems organized by interactions between biological components interacting with physical environments, and become a unified whole with capacity to maintain homeostasis and self-perpetuation BBA Part1_1 (Gajaseni, 2001)

  8. Sign of life • 1. Highly complex organization = all other characteristics of life emerge from an organism’s complex organization BBA Part1_1 (Gajaseni, 2001)

  9. 2. Self-homeostasis = Self-maintenance of a steady-state internal environment in the variations of external environment. BBA Part1_1 (Gajaseni, 2001)

  10. 3. Self-perpetuation = Life comes only from life. BBA Part1_1 (Gajaseni, 2001)

  11. BBA Part1_1 (Gajaseni, 2001)

  12. BBA Part1_1 (Gajaseni, 2001)

  13. 4. Growth and development = the increment of volume and changes in structure and functions to suit with new form of life BBA Part1_1 (Gajaseni, 2001)

  14. BBA Part1_1 (Gajaseni, 2001)

  15. Insert larva picture BBA Part1_1 (Gajaseni, 2001)

  16. 5. Interactions = Life needs energy and matter utilization for maintenance of life BBA Part1_1 (Gajaseni, 2001)

  17. BBA Part1_1 (Gajaseni, 2001)

  18. BBA Part1_1 (Gajaseni, 2001)

  19. 6. Adaptation = Life evolve as a result of the interaction between organisms and their environments BBA Part1_1 (Gajaseni, 2001)

  20. BBA Part1_1 (Gajaseni, 2001)

  21. 7. Response = Life adjusts itself to the environment. BBA Part1_1 (Gajaseni, 2001)

  22. BBA Part1_1 (Gajaseni, 2001)

  23. BBA Part1_1 (Gajaseni, 2001)

  24. BBA Part1_1 (Gajaseni, 2001)

  25. From biological perspective, these are biological spectrum • Biotic components BBA Part1_1 (Gajaseni, 2001)

  26. Gene รูป biotic component Cell Organ Organism Communities Populations BBA Part1_1 (Gajaseni, 2001)

  27. Biotic components cannot survive in isolation. They must interact with physical or a biotic environments. BBA Part1_1 (Gajaseni, 2001)

  28. Generalized diagram of inputs, throughputs, and outputs in a system System Throughputs (flows) System Inputs System Outputs Information Energy Matter Useless information Waste heat Waste matter BBA Part1_1 (Gajaseni, 2001)

  29. Interaction between each biotic level with physical environment through energy, matter, and information produces characteristic functional system. "Biosystem" or "life" BBA Part1_1 (Gajaseni, 2001)

  30. Organizational hierarchy in nature can be seen from "universe" down to "subatomic particles". BBA Part1_1 (Gajaseni, 2001)

  31. Milky way Universe Galaxy รูป solar system Solar system Earth BBA Part1_1 (Gajaseni, 2001)

  32. The natural world is organized, diverse, dynamic, and yet complex. BBA Part1_1 (Gajaseni, 2001)

  33. Q. How can life be seen in nature? A. A hierarchy of organization of matter. BBA Part1_1 (Gajaseni, 2001)

  34. Fig 3-6 BBA Part1_1 (Gajaseni, 2001)

  35. Then, there is hierarchy of biosystems. BBA Part1_1 (Gajaseni, 2001)

  36. Q. What is the determinant of life? A. Environment by evolutionary processes. BBA Part1_1 (Gajaseni, 2001)

  37. Fig 20’ BBA Part1_1 (Gajaseni, 2001)

  38. Q. How did life emerge on the Earth? BBA Part1_1 (Gajaseni, 2001)

  39. Fig 8-11 (21’) BBA Part1_1 (Gajaseni, 2001)

  40. Chemical evolution 1 billion years Biological evolution 3.7 billion years Transparency 78 Fig 6-5 summary of the evolution of the earth and its life. BBA Part1_1 (Gajaseni, 2001)

  41. Q. Is human a hierarchy of organization of matter? BBA Part1_1 (Gajaseni, 2001)

  42. Q. What is the difference of “interaction between man and environment”and “interaction between other organisms and environment”? BBA Part1_1 (Gajaseni, 2001)

  43. BBA Part1_1 (Gajaseni, 2001)

  44. A. Organisms adapt themselves to the environments. • While “Human modify environments to suit themselves ”. BBA Part1_1 (Gajaseni, 2001)

  45. Human environment 2 groups BBA Part1_1 (Gajaseni, 2001)

  46. 1. Natural environment: 4 spheres • 1.1 Biosphere = Space occupied by life • 1.2 Atmosphere = Space occupied by air • 1.3 Lithosphere = Space occupied by solid • 1.4 Hydrosphere = Space occupied by water BBA Part1_1 (Gajaseni, 2001)

  47. How do the 4 spheres really exist? BBA Part1_1 (Gajaseni, 2001)

  48. Atmosphere Ecosphere Biosphere Hydrosphere Lithosphere BBA Part1_1 (Gajaseni, 2001)

  49. 2. Man-made environment • 2.1 Anthropogenic ecosystems • 2.2 Physical structures BBA Part1_1 (Gajaseni, 2001)

  50. What are the Functions of Natural Environment? BBA Part1_1 (Gajaseni, 2001)
