19 Despite Gains, Millions Go Hungry

20 World Totals (million hectares) Vegetation Removal579 Overexploitation133 Overgrazing679 Agricultural Activities522 Industrial and Bioindustrial 23 Degraded Soil Means Less Food

21 Food Supply Increasingly Relies on Irrigation

22 Farmed Fish Are a Growing Share of the Global Fish Harvest

23 What Do Industrial Economies Use?

24 Paper Use is Growing Worldwide

25 Paper Recycling: Rising Volume, Growing Importance

26 Vehicle numbers are rising dramatically

27 Motor vehicle use is highest in developed countries

28 Surface temperatures have warmed over the past century 60 59.5 59 58.5 58 57.5 154 152 150 148 146 144 142 18601880 1900 1920 1940 1960 1980 2000 Temperature (Fahrenheit)Temperature (Celcius)

29 Greenhouse gas warming

30 Per capita CO 2 emissions are small in developing countries (metric tons of carbon dioxide)

31 Developed nations have altered the atmosphere most

32 Stabilizing CO 2 means steep emission cuts eventually

33 Success story: CFC production has fallen sharply

34 Backsliding: Halon production is rising again

35 Excess nutrients may spur algal blooms Pre 1972

36 Excess nutrients may spur algal blooms Post 1972

37 More fertilizer: More food, but more pollution too

38 SO 2 emissions in Asia could triple

39 NOx levels are still a problem in Europe and North America

40 Forest Loss Is Severe in the Tropics

41 Amazon Deforestation Remains High

42 Many of Earth’s Forests Have Been Cleared or Degraded

43 Water Demand is Growing, But Supplies Are Limited

44 Agriculture Dominates Water Use, But Its Share Will Decline

45 Low-Income Nations Are Especially Vulnerable to Water Scarcity

46 River Habitats Have Been Heavily Altered

47 How Much Are Nature’s Services Worth? Global GNP (US $18 trillion) Ecosystem Services (US $33 trillion) Ecosystem Services (US $33 trillion)

48 Reef Threats Are Extensive

49 Some Fish Stocks Have Collapsed from Overfishing COD CATCH NON COD CATCH

50 Bird Populations Are Under Siege Worldwide
