Points from GEO-4, major UN environment report
« on: October 26, 2007, 08:40:09 AM »
Following are key points from the fourth Global Environment Outlook (GEO-4) report, issued on Thursday by the United Nations Environment Programme (UNEP)

-- Humanity's current "footprint", or environmental demand, is 21.9 hectares (54.75 acres) per person, while Earth's biological capacity is only 15.7 hectares (39.25 acres) per person

-- In Africa, per capita food production has declined by 12 percent since 1981

-- Developing countries will probably need another 120 million hectares (463,000 square miles), an area nearly the size of South Africa, to feed themselves by 2030

-- The proportion of Africans living below the poverty line rose from 47.6 percent in 1985 to 59 percent in 2000

-- Availability of clean freshwater is declining yet water use is predicted to be risen by 50 percent in developing countries by 2025

-- Ten percent of the world's major rivers fail to reach the sea for part of the year because they are so drained for irrigation

-- Fishing capacity, helped by subsidies, is 250 percent greater than the oceans' sustainable catch

-- Eleven of the warmest years since 1850 were recorded in the last 12 years

-- Global average temperatures have risen 0.74 degrees Celsius (1.33 degrees Fahrenheit) since 1906. They are expected to rise by 1.8 to 4 C (3.24-7.2 F) this century.

-- Some greenhouse gases may persist in the atmosphere for up to 50,000 years

-- 2007 will be the first year in history when the majority of people will be living in cities

-- 60 percent of the world's population lives within 100 kilometres (60 miles) of the coast

-- Coastal erosion causes Togo and Benin to lose 30 metres (33 yards) to the sea each year

-- Over the past 20 years, the world has cut the production of ozone-layer damaging chemicals by 95 percent

-- An estimated two million people die prematurely each year from air pollution

-- Of major vertebrate groups on the planet, 30 percent of amphibians, 23 percent of mammals and 12 percent of birds are threatened
