Humans and other species: The human causes of extinction (documentary)

    1. Why are our planets untouched natural environments shrinking?
- because of pressures from human population

     2. How many species could be gone in 100 years?         Why?
-  half the species could be gone in 100 years because of the effects of human degradation of the biosphere.

 
    3. What are the consequences of humans ‘high quality’ lifestyle?
- it leads to a poorer and untenable life by most of the creatures we share the planet with. Its states that the current human consumption of the planets natural resources puts any animal walking on the ground, hanging in the tree or swimming in water at risk of extinction.
  
    4. What does the Living Planet Index measure?
-    populations of terrestrial and marine species dropped by 30 % while fresh water population went down by 50%. It tracks trends in population in more than a thousand species and also examines the consequences of human consumption ranging from fishing in Hungary to polluted rivers in Kenya
-    uses ecological foot print as a benchmark to compare current level of human consumption with past findings.
 
    5. What does the Living Planet Index blame loss of species on?
- increasing human demand of food, fibre, energy and water.

    6. How is South East Asia threatening species diversity?
-    If logging continues at its current rate these forest will be gone in less than 5 years.
-    In Indonesia and Malaysia, forests are being burnt down and will be replaced by oil palm plantations.

Your PERSONAL PERSPECTIVE: Are other species important? Explain  your opinion?


Summarise the key points…

This video is talking about the extinction of animals because of the human consumptions. It is said that half the world’s species will be gone in 100 years. Moreover, people are deforesting by logging or burning the whole forest down to either make money on logs or to plant oil palms. If this continues, the forests will be gone in 5 years. Another thing people even do, is illegal trading of animals because they no longer have a home as it is either being cut down or burnt and this happens in Bangkok, Thailand. They also mentioned that in India, the offcicials estimate that there are about 3700 tigers but the wildlife experts estimated that the amount of tigers are nearing 2000.
