  • 1. Why biodiversity is important
  • 2. Because……all life deserves toexist in its own rightand is more beautifuland mysterious than anything the human mind can conjure.“One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvellous structure of reality.” Albert Einstein
  • 3. Because……just as genetic diversity increases the odds of survival within species, species diversity increases the odds of survival for life as a whole. When a species exhibits great genetic diversity, it has a larger pool of genesavailable to it. Having more genes makes the species better equipped to respond to changing conditions. In the same way, species diversity is nature’s way of assuring longevity for the existence of life on earth. Species diversity is life’s way of protecting itself. Humans are only one tiny strand of this magnificent strategy.
  • 4. Because… …humans are genetically predisposed to value life, and by presiding over species extinction, we deny our own nature. Evolutionary biologist E. O. Wilson, says species loss may go against biophilia, or the tendency of humans to focus on life and lifelike processes. If this is true, then contributing to the destruction of living things goes against what it means to be human.Source: http://science.howstuffworks.com/environmental/conservation/issues/biodiversity-important1.htm
  • 5. Because… …all the progress ever made by humans has drawn its inspiration and materials from nature’s bounty. Humans rely heavily on the great variety of organisms that share the planet with us. Plants, animals, bacteria and fungi provide raw materials for human use. We base our diets on food crops and the animals that eat them. We clothe ourselves using material derived from plant and animal fibres. We take advantage of single-celled organisms, from bacteria to yeast, to drive important industrial and manufacturing processes. Almost 40 percent of all prescription drugs sold worldwide contain natural compounds found in different plant, animal and fungal species [source: USAID]. Penicillin stands as a classic example of how humankind has benefitted from a drug obtained from another organism.Source: http://science.howstuffworks.com/environmental/conservation/issues/biodiversity-important1.htm
  • 6. Because… …a species-rich ecosystem is more sustainable than one which is species- depleted. Pollination is just one service provided by the complex interplay of living things. Ecosystem services also purify water, generate fertile soil, break down wastes, help control pests and moderate weather extremes.Source: http://science.howstuffworks.com/environmental/conservation/issues/biodiversity-important1.htm
  • 7. Because……every species plays a unique part in themagnificent biosphere that sustains all life,including humans.• The biosphere is an awe-inspiring and delicate system, the complexities of which we cannot hope to understand. Despite all our ingenuity, we have never come close to emulating nature’s beauty, sustainability and balance.• Systems thinking tells us that changing one part of a system can wreak unintended consequences in another part.“Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect.” ― Chief Seattle, 1854
  • 8. Because… …humans and all other forms of life are interconnected, evolved from the same source.…extinction is final and represents the loss of millions of years of unique evolution. …there is a virtuous circle at play herewhere more life begets more life, and less life begets less life. When we destroy other forms of life, we destroy ourselves.
