1. Food Supply

2. Crops 3. Livestock 4. Fishing 5. Forestry Seeds- Wheat, rice Leaves Lettuce, Celery Roots- Carrots 6. Pest Control Using animals instead of harmful pesticides 7. 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 8. Quinine comes from the cinchona tree has been used to treat malaria. 9. Morphine from the poppy plant gives pain relief. 10. Economics 11. In Industry Fibres for clothing 12. Wood for housing 13. Animals may be used as transport or labour 14. Tourism Biodiversity is a source of economic wealth for many regions of the world. 15. Nature Reserves (Kruger National Park) 16. Forests and parks (Kirstenbosch) 17. All of these result in economic growth for a country. 18. Poaching 19. Poaching Is the illegal killing of animals to eat or sell. Due to this species may become extinct 20. Habitat Destruction 21. 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. 22. 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 23. Golf estates/courses They may be grassy and beautiful but they have very little biodiversity. When they are built the original environment is destroyed. 24. Mining: As South Africa grows so does the peoples demands for goods and more factories are built. Habitats and ecosystems are destroyed when factories and mines are built. 25. 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. 26. 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 27. Invasive Alien Species 28. 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. 29. 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. 30. 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. 31. So what is there to do? 32.
