Slide 1: HAS MANKIND CONSERVED
BIO DIVERSITY??? RUBY HOUSE AGAINST THE MOTION Slide 2: present FUTURE Slide 3: WHAT IS BIO DIVERSITY? Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. This includes genetic diversity within and between species and of ecosystems. Slide 4: CHANGES IN BIO DIVERSITY
OVER YEARS This figure is called the Living Planet Index; it was compiled by the World Wildlife Fund in 2005, and is based on data for several groups of marine, freshwater, and terrestrial animal species. As you can see, abundance of all has declined since 1970 levels Slide 5: THREATS TO
BIO DIVERSITY?? DEFORESTATION
RAPID KILLING OF ANIMALS
AND MAN Slide 6: RAPID CUTTING OF FORESTS Slide 7: Deforestation is the clearance of naturally occurring forests by the processes of logging and/or burning of trees in a forested area.
There are several reasons deforestation occurs: trees or derived charcoal can be sold as a commodity and used by humans, while cleared land is used as pasture, plantations of commodities and human settlement. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity Slide 8: RUTHLESS CUTTING
FOR GROWING POPULATION Slide 9: What do you understand
From it ?????? Slide 10: Cruelty to Animals Animal cruelty is a worldwide problem rapidly growing in today's society. Animals are being beaten and starved everyday and millions of helpless animals die each year because of heartless owners. Slide 11: ELEPHANTS and RHINOCEROS are widely killed all over the world for their tusks an skin
They are on the edge of becoming extinct Slide 12: A few extinct animals DINASAURS MAMMOTH DODOS Animals in the race of becoming extinct ETC. PANDAS RHINOCEROS POLAR BEAR Slide 13: Loss of bio diversity has
Resulted in Global Warming PICTURE OF GLACIERS
50 YEARS AGO PRESENT CONDITIONS OF GLACIERS Slide 14: HOTSPOTS OF BIO DIVERSITY 1 Rainforests are experiencing biodiversity loss at rates greater than most other habitat types. The primary cause of rainforest loss is deforestation for timber, cattle grazing, and farming 2 Wetlands are another habitat being lost at great pace. Wetlands are very important to humans for a number of reasons, including storm mitigation and water filtration Slide 15: 3 Coral reefs are extremely sensitive to changes in ocean temperature, and “coral bleaching” results when temperatures get too high; this phenomena will eventually kill corals if the temperature does not return to suitable levels SPECIES 4 Increased human use and pollution of the river degraded its habitat to the extent that it has been declared extinct The Golden Toad was a small, brightly colored toad .It has been extinct since 1989 Polar bears are one of the most well-known victims of climate change, because of global warming, they could be extinct by the end of this century. Slide 16: DARKEST SIDE OF LOSS OF BIO DIVERSITY Drowning of Earth because of melting
THIS DAY IS NOT FAR Slide 17: M a n's f u t u re
