  4. 4. Your Logo or Name Here Extinction Dying off or extermination of a species Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world - the species has died out. This is a natural part of evolution 4
  5. 5. Your Logo or Name Here Endangered A species that is seriously at the risk of extinction 5 • Endangered means for a species to be at risk of becoming extinct from Earth meaning the species population has dropped so low that it is at risk of becoming extinct in the wild.
  6. 6. Your Logo or Name Here 6 Causes
  7. 7. Your Logo or Name Here Habitat Loss Destruction, fragmentation or degradation of habitat 7 • Deforestation and urbanization combine to create two reasons why plants and animals become extinct. • Deforestation is leveling forests to harvest the wood or create space for building or agriculture, while urbanization is the turning of once-rural areas into cities. • As the human population grows, more and more land has to be cleared and urbanized for living space.
  8. 8. Your Logo or Name Here Global warming Global increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs and other pollutants. 8 • Global warming is the ongoing increase in the Earth's atmospheric and ocean temperatures created by the greenhouse effect; • a temperature increase of even 1 degree can affect plant and animal life.
  9. 9. Your Logo or Name Here Exotic Species An introduced species that is found outside of its natural range. 9 • When animals and plants that are not native to a region are introduced to the ecosystem, they can cause serious damage to the local plants and animals, and potentially contribute to their extinction. • Native species must compete with the exotic species for basic needs such as food and water. • If the exotic species is more aggressive than the native species, the native species then runs the risk of extinction.
  10. 10. Your Logo or Name Here Overexploitation Harvesting species from the wild at rates faster than natural population can recover. 10 Overexploitation, also called overharvesting, is the excessive harvesting of an animal or plant species, making it harder for the species to renew its numbers.
  11. 11. Your Logo or Name Here How To Protect Them From extinction 11 • We should educate people from the young age about the importance of plants and animals in maintaining the ecosystem and biodiversity. • Young people should be educated how to protect our environment in general and how to protect endangered animals in particular.
  12. 12. Your Logo or Name Here How To Protect Them From extinction 12 • They should be told about the things that threat the safety of wildlife so that they can avoid doing them. • This should be included in their curriculum at school. • One of the most important ways to help threatened plants and animals survive is to protect their habitats permanently in national parks, nature reserves or wilderness areas.
  13. 13. Your Logo or Name Here How To Protect Them From extinction 13 • There they can live without too much interference from humans. It is also important to protect habitats outside reserves such as on farms and along roadsides. • Each nation must enforce stricter law with more serious punishment- capital punishment, for example- to prevent people from poaching rare and valuable animals.
  14. 14. Your Logo or Name Here Routine Measures To save plants from extinction or being endangered 14 • Plant trees. This will help create homes for animals. Planting trees can also help curb the impacts of climate change – one of the major drivers of biodiversity loss. • Save on energy. • Save on paper. • Save on fuel. • Learn more about biodiversity and share it
  15. 15. Your Logo or Name Here Routine Measures To save plants from extinction or being endangered 15 • with your family, friends, and colleagues. • Do not patronize wildlife products (fur, tusks, hooves, etc). • Recycle and re-use. Better yet, spearhead a recycling drive. • Turn off the lights in an empty room. • Stop using plastic bags.
  16. 16. Your Logo or Name Here Because . 16 • Biodiversity is the variety of life (its ecosystems, populations, species and genes). • Saving endangered species (plants and animals) from becoming extinct and protecting their wild places is crucial for our health and the future of our children. • As species are lost so too are our options for future discovery and advancement. • The impacts of biodiversity loss include clearly into fewer new medicines, greater vulnerability to natural disasters and greater effects from global warming.
