2. “ The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.” _____________________________ Thomas Malthus, 1789 THE VERTICAL SHIFT: AVOIDING THE MALTHUSIAN CATASTROPHE BY GORDON GRAFF

5. Linear Consumption of Land Dust Bowl – 1930s USA William B. Greeley, The Relation of Geography to Timber Supply, Economic Geo. 1925 DUST BOWL – 1930s US MID-WEST

6. Linear Consumption of land About ½ of the mature tropical forest cover of the earth has been destroyed, somewhere between 750-800 million hectares

7. Linear Consumption of land AFGHANISTAN 70% loss Between 1990 and 2005 Afghanistan lost 33.8% of its woodland habitat. In total, 70% of its forests have been destroyed.

8. Nigeria presently has the highest rate of deforestation of primary forests, according to the UN. Between 1990 and 2005 the country lost 35.7% of its forest cover. All together, 79% of Nigeria’s primary forests have been destroyed. Reasons: Logging, Subsistence Agriculture, Collection of Firewood Linear Consumption of land NIGERIA 79% loss

9. Linear Consumption of land MADAGASCAR 94% loss Madagascar’s rampant deforestation has resulted in extensive desertification, water resource degradation, and soil loss. Approximately 94% of its biologically diverse lands have been destroyed, nearly all of which has occurred since claiming independence from France in 1958. This is disheartening when considering 5% of the earths plant and animal species are located in Madagascar, most of which are endemic.

10. Linear consumption of land PHILIPPINES +90% loss At one time 95% of the land area of the Philippine archipelago was covered by tropical rainforest Today, over 90% of this diverse ecosystem has been destroyed The Philippines is ranked as having the most severely endangered mammal and bird faunas in the world
