3. Food Supply

4. Crops

5. Livestock

6. Fishing

7. Forestry
Seeds- Wheat, rice
Leaves – Lettuce, Celery
Roots- Carrots

8. Pest Control
Using animals instead of harmful pesticides

10. Medication
A wide variety of plants, animals and fungi are used
as medicine
Over 60% of world population depends on the plant
medicines for their primary health care

11. Quinine comes from the cinchona tree has been
used to treat malaria.

12. Morphine from the poppy plant gives pain relief.

13. Economics

14. In Industry
Fibres for clothing

15. Wood for housing

16. Animals may be used as transport or labour

17. Tourism
Biodiversity is a source of economic wealth for many
regions of the world.

18. Nature Reserves (Kruger National Park)

19. Forests and parks (Kirstenbosch)

20. All of these result in economic growth for a country.

22. Poaching

23. Poaching
• Is the illegal killing of animals to eat or sell.
• Due to this species may become extinct

24. Habitat Destruction

25. Habitat Destruction:
 It is difficult to control habitat destruction because
people and other organisms compete for the same
land.
 More people need more and more space to live
and grow food, therefore destroying habitats.

26. Farming Methods:
Monoculture
 Most commercial farms practice
monoculture (meaning they only grow
one kind of crop)
 Is the most effective method of growing
food
 Most wild animals and indigenous plants
are not suited to live in farmlands

27. Golf estates/courses
 They may be grassy and beautiful but
they have very little biodiversity.
 When they are built the original
environment is destroyed.

28. Mining:
 As South Africa grows so does the
people’s demands for goods and more
factories are built.
 Habitats and ecosystems are destroyed
when factories and mines are built.

29. Deforestation:
 People cut down indigenous trees to:
-Sell the wood
-Clear land for building/agriculture
-Use wood as an energy source (rural SA)
 Def: Is the permanent destruction of
indigenous forests and woodlands.

30. • The plants and animals that are adapted to their
environment will die out.
• Some species will become extinct
• It will result in a loss in biodiversity

31. Invasive Alien Species

32. Impact on ecosystems
 When invasive alien species increases, the number of
indigenous species within that particular habitat
decrease.
 This leads to less food (plants) for the animals to feed on.
 The local food web is then disrupted and some
indigenous plants may become extinct.
 The invasive alien species may not be palatable for the
local animals, therefore the animals either die out or
move away.

33. Threats to fynbos
 Fynbos is threatened by the increase in
urbanisation and agricultural land.
 Many species have such a small area in
which they grow that building a house
may make the species go extinct
 Invasive alien plants compete with the
Fynbos and use a lot of water.

34. Overall what threat to fynbos
leads to:
 The over exploitation of plants may lead
to the extinction of that species and can
have detrimental consequences.

35. So what is there to do?

36. Support our cause, and
save Biodiversity
