  2. The Earthis fragile and unique GL/2010

  3. The universeisemptywith a few exceptions !The Sun is essential to life itsdiameteris 1 392 000 kilometres. If the Sun was as big as a grapefruit, the Earthwouldbe as big as a pinhead. GL/2010

  4. Whatwouldbe the distance between the grapefruit and the pinhead to have the equivalent of 149 600 000 km? 15 metres ________________ GL/2010

  5. Plutoisat the boarder of the solar system atwhat distance woulditbe ? 605 metres ! Pluto is only 5/10thmm and is hardly visible : . It is so far from the Sun that its average temperature is -229°C. Life is impossible. ________________ GL/2010

  6. Wherewouldbe the Sun’snearest star ? 4050 km ! _____________ Proxima Centauri is a red dwarf, it is situated at 4.22 light years from the Sun (speed of light: 300 000Km/S) GL/2010

  7. The Spaceisexactlylikethat – First you place a « Sun/grapefruit », youflyduring 4050 km and you place the second star. Between the twothereisabsolutelynothing - emptyness ! GL/2010

  8. If humanitythrows the Earthaway, therewillbe no otherEarth, if another one existsitwillbetoo far for our rockets! GL/2010

  9. Our Sun belongs to the MilkyWay, itis OUR Galaxy, look atit ! GL/2010

  11. This photo wastaken by Hubble spacetelescope, itisshowing the inside of the Universe, each point is a galaxy. The photo’s field of view is the size of a button which would be positioned 25 meters from an observer. GL/2010

  12. At the end of its life a star explodes and becomes a Supernova and itsendsitsatomseverywhere In 1054, the Chineseobserved the explosion of this star which has become the CrabNebula. Eachcolouris made by a differentgas. _______________________________________________________ GL/2010

  14. Humanbeings are made of 65% oxygen, 18% carbon and 10% hydrogen – sowe are all made of « star dust » ! Pioneer probes left the earth in 1972. This golden plate wasnailed on themsothatextraterrestrialscouldseeit! The two Pioneer probes went out of the solar system in the 80’s. _____________________________ GL/2010

  16. But Humanitydeclaredwar on Nature GL/2010

  17. Night life on Earthseenfrom a satellite. It shows humanactivities. Urban lights Oil wells Forest fires Fishing by lamplight (You fish at night on boats, and you light up the sea to lure fishes) GL/2010

  18. During the last 100 years people have burnt more thanhalf of the oilthatEarthspent 100 millions years to make. GL/2010

  19. Deforestation of Borneoprimaryforest. GL/2010

  20. People fishtwice as manyfish as beingbornt. « Fish supplies » cannotberenewed. Fishing by lamplight is so productive that it is emptying the oceans. GL/2010

  21. Humanbeingsrejectstwice as muchgreenhouseeffectgas as nature canabsorb. The excess of gasremainstrapped in the atmosphere This picture was taken from the space shuttle, it shows the very thin coat of atmosphere around the Earth, only 100 km. GL/2010

  22. The greenhouseeffectgaseven if they come from nature itself are responsible of global warming. GL/2010

  23. Global warmingcanbeseenwith the melting of glaciers Grinnell Glacier ‘s melting in Montana (USA) 1938 1981 1998 2005 GL/2010

  24. In the past, the Earthhad 5 major climatechangingsleading to massive extinctions of many animal species. The Cretaceous period (dinosaurs,ammonites) 60% 50 40 30 20 10 0 Disapeared species 542 500 450 400 350 300 250 200 150 100 50 0 million years GL/2010

  25. It looks as if a sixth massive extinction of animal speciesisatworkat the moment, itwouldbebetter if humanbeingswere not part of it! • The world population is 6,860 billions of people on June 20th 2 010 • 4 babies are bornevery second • Wewillbe 9 billions a littlebefore 2050 • Evolution live: http://www.geopopulation.com GL/2010

  26. The fear of a demographic explosion is going away, human fertility is going down and the growth of the population is stabilizing little by little GL/2010

  27. The question is « how are wegoing to be able to feedcorrectly the world population ? » GL/2010

  28. Even if we do not consider religious ideologies, human beings are the first beings able of compassion, they deserve to stay on the planet! GL/2010
