The ecological concept of biodiversity. An obsolete concept? What relevance does it have for our lives. What relevance does it have for the lives of other organisms. |

Peter Raven, President of the International Botanical Congress at its 16th
worldwide conference, August 2, 1999 announced: |

We pose these questions. On a scale of one to ten how important is biodiversity to you? Which is more important to you: how much money you make or how much biodiversity you preserve? Can you personally preserve biodiversity? If decreasing biodiversity affected your ability to hold a job or threatened the world's food supply, would you think more about it? How much time do you spend each day thinking about biodiversity? How often do you discuss biodiversity with family? Friends? Strangers? Would you rather the whales die of harpoons, toxic pollutants, or lack of food? While the temperature of the earth has risen just under a degree Celsius, the temperature of the Antarctic has risen almost five degrees. Due to increases in UV at the poles, there has been a 90% reduction of krill. Do you agree that the earth is not fragile and that the goodness of a tree is the things which can be made from them after they are cut down? When a tree grows, does it take a lot of carbon out of the air? How much carbon is added to the atmospherewhen a forest is denuded? Do trees have a nurturing effect on other plants, animals, and microorganisms around them? Do trees stop soil erosion and denuding of the earth? Do we feel less guilty after planting a tree? If everyone planted a tree would that increase the earth's biodiversity significantly ?
When we add four billion more people, if they all buy a car and a picture perfect American home and each plant a hundred trees, what net effect would that have on biodiversity? How many decades would be required to see any effect, however slight, from planting some trees? How important is it to you that in the last two hundred years an absurdly large number of kinds of life forms have become extinct? How important is it to you that this rate of extinction is increasing? How important is it to you that while over fifty per cent of the earth's species had lived between the Tropic of Capricorn and the Tropic of Cancer, mainly in the rain forests, 88% percent of the Asian rain forests, 60% of the African rain forests and 30% of central and south American rain forests are gone? Another 2% of central and south American rain forests have been burned so far this year(2000), which is equal to the annual rate of loss for these forest habitats. And the rate of this destruction is increasing not decreasing. Whats's the problem? Do you hope that the rain forests won't disappear because you feel sad for cute furry little animals, some of which look just like humans and can even show us their intelligence by learning tricks? Do you hope that the rain forests won't disappear because the plants may yet give us a new facial lotion or a new drug for cancer? How can extinct life forms benefit from our planting a large number of trees? Japanese school children are taught that kenafe grows faster than trees; what if we planted lots of kenafe as well as trees? Is the overall effect of destroying forests and planting trees the lowering of the earth's biodiversity? Do you try not to think about how far the people in the poor countries will push human overpopulation? Do you believe it is ok for developed countries to maintain high populations as long as they are at or near zero population growth, not including immigration? Do you think America has a high population? Are you on a waiting list to visit any of the national parks? Were you alive and looking around you in say, 1955? Have you ever talked to your grandfather or grandmother about the animals and plants that existed when they were children back in 1896? In the movie Apocalypse Now, Martin Sheen made the following comment after his soldiers had just killed a boatful of Vietnamese men, women, and children, "We cut them in half with an M-16 and then give them a Band aid." Humans have just such a band-aid approach to biodiversity. Non-human organisms pay neither taxes nor tithe. Animal rights? The right to habitat? Nope. The right to life? Nope. They have no rights. Unless they are cute, edible, or their presence contributes to the illusion that the world isn't overpopulated by humans. No other vertebrate land organism has attained a population of ten billion. Can you give one reason why Homo sapiens should attempt to be the first?

If tomorrow and every day thereafter you tell a family member, a friend or a stranger that the population of the world should come down, as soon as possible, we can just about guarantee that your intelligence as well as your motivation will become suspect. If you continue, you will likely become despised. Ask Ted Turner what it's like. Everyone is well aware of the social, cultural, economic and religious ramifications of lowering the population. Lowering the population means having children responsibly. What about you; do you not think responsible reproduction is a sound and rational idea? How much more of the earth's biodiversity are you willing to watch disappear before you consider changing your mind? |

You may wish to travel the world and gain a better appreciation of biodiversity. WWF is highlighting two special voyages. All WWF trips are designed with the conservationist in mind, and provide the opportunity to see firsthand the many wild spaces and species in need of protection. Throughout these journeys, experienced and personable naturalists will illuminate your experience and guide your voyage. Please visit www.worldwildlife.org/travel for more schedules, offerings, and further information. --Spotlight on Right Whales: At one time, the global population of right whales
(both northern and southern) may have numbered 80,000, and they could be found off the
coast of every continent. Today the northern right whale is all but extinct in the
eastern North Pacific, only a small population exists in the northwestern Pacific,
probably in the low hundreds, and approximately 300 exist in the western northern
Atlantic. The northern right whale is the most endangered of the large whales. Only in
the Southern Hemisphere are right whales showing signs of recovery. The two largest
populations are found off South Africa and Patagonia, but the species is also found in
the waters off Australia and some coastal areas of the South Pacific. Right whales most
distinctive features are their callosities - raised, thickened, patches of skin, which
grow on their head, lips, and chin. The callosities' patterns, which vary from whale to
whale allow researchers to distinguish individuals. To find out more about whales or
other species, please visit our web site: --Watch for these incredible whales up-close and personal as you travel with WWF to Patagonia, Falklands, Tierra del Fuego, and the Chilean Fjords from November 22-December 8, 2000 aboard the 110-passenger Caledonian Star. The trip also includes: visits to Buenos Aires, Argentina and Montevideo, Uruguay; opportunities to observe remarkable concentrations of sea lions and elephant seals at Puerto Madryn and the Valedes Peninsula in Argentina; 3 days exploring the Falkland Islands where many penguin species abound; and 2 days exploring the Chilean fjords' incredible vistas. Special Offer: The cost of the voyage runs from $7,990 per person, double occupany. However, if you register by June 22, WWF will reduce the trip price by $1,000 per person an excellent value for an outstanding wildlife experience. For more information, contact the Travel Program by phone(1-888-WWF-TOUR) or via e-mail: membertours@wwfus.org --Spotlight on the Amazon: The Amazon is the world's largest intact rain forest.
With its high rainfall, complex topography and soils, and meandering river systems, the
Amazon creates habitat mosaics that contribute to the diversity of the region. Each year,
the Amazon River overflows its banks and floods 116,000 square miles of forest. These
forests form the most extensive system of riverine flooded forests on Earth and their
streams and rivers contain 20 percent of the planet's freshwater. The Flooded Forests of
the Amazon host an extraordinary seasonal migration of aquatic and terrestrial animals.
Red uakari, hoatzins, pink freshwater dolphins, Amazon manatees, giant kapok trees are
just a few of the remarkable species found in those forests. The Southwestern Amazon Rain
Forests provide one of the last refuges for the highly threatened jaguar, the harpy
eagle, and the giant river otter. These forests also support as many as 1,200 species of
butterflies. Currently, the biggest threat to these crucial ecosystems is overpopulation
of the surrounding lands causing roads, logging,and agriculture to encroach on many
protected areas. Please visit us on-line to learn more about important ecoregions: --Travel through the rain forest on the Amazon Riverboat Voyage aboard the 26-passenger La Turmalina - The itinerary includes exploring a succession of rivers (the Amazon, Ucayali, Tapiche, and Sabina Rivers) full of remote areas that cannot be navigated by larger ships, walking through the rain forest to observe the incredible diversity of life, and visiting isolated villages that depend upon the forest and river for sustenance and commerce. Dates include September 30-October 8 and November 11-19, and cost $2,970 per person, double occupancy. March 31-April 8 and April 28-May 6, and cost $3,125 per person, double occupancy.
