I lifted this information from an article I found on he internet. It was presented as a primer for those interested in the context for the global 20+ Rio Environmetnal Summit slated for late June, 2012.
- POPULATION: Seven billion today, a
doubling since 1950, and set to rise to 9.3 billion by 2050, of which
two-thirds will live in cities. The population in poor countries has increased
more than fourfold since 1961. Forty percent of the world's population today
now lives within 100 kilometres (62 miles) of the shoreline.
- ECOLOGICAL FOOTPRINT: Mankind
today is gobbling up 50 percent more of the biosphere
for our resources and waste than it can sustain. Brazil, China, India and
Indonesia have seen their per-capita footprint increase by two-thirds over the
past half century. The United States and China together use up nearly half of
the global biocapacity. In per capita terms, rich countries' footprints are around
four or five times greater than that of poor economies. The hefiest impacts per
capita are made by Qatar, Kuwait and the United
Arab Emirates respectively.
- POVERTY: The number of people
living on $1.25 (one euro) a day fell from 1.9 billion in 1990 to 1.289 billion
in 2008, or 22 percent of the developing world. For the first time in 20 years,
the proportion of Africans living in extreme
poverty has fallen, with 47 percent living below this threshold in
2008 compared with 52 percent in 2005. But 43 percent of the population in
developing countries live on less than $2 (1.6 euros) a day.
- BASIC SERVICES: More than 2.5
billion people are in need of decent sanitation and nearly one in 10 has yet to gain
access to "improved" drinking water, as defined under the UN's 2015
development goals. 1.4 billion people have no mains electricity.
- CLIMATE
CHANGE: Emissions of man-made greenhouse
gases are scaling new peaks and the early signs of climate change
are already visible, in glacier melt, changed snowfall and habits of migrating
species. Current pledges for curbing carbon
emissions will lead to warming of 3.5 degrees Celsius (6.3 degrees
Fahrenheit), massively overshooting the UN target of 2 C (3.6 F) and enhancing
the risk of flood, drought, storms and rising seas.
- BIODIVERSITY: In 2002, the international
community pledged to slow biodiversity decline by 2010, and incorporated the
target into the UN's Millennium Development Goals. But the drop-off has
accelerated, driven especially by habitat loss. A fifth of mammals, 30 percent
of amphibians, 12 percent of known birds, and more than a quarter of
reef-building corals face extinction, according to the "Red List" of
threatened species.
- ENERGY: World energy consumption
rose by 5.6 percent in 2010 and is set to double by 2030. Fossil fuels account
for more than 80 percent of the energy supply, followed by renewables with
around 13 percent, of which biofuels is by far the biggest contributor. In
rural Africa, 85 percent of the population relies on biomass for energy.
- DEPLETED RESOURCES: Between 2000
and 2010, 13 million hectares (32.5 million acres) of forests disappeared each
year, accounting for the third biggest single source of greenhouse gas. Fish
catches increased fivefold between 1950 and 2005. Thirty percent of fisheries
are over-exploited, depleted or recovering from depletion. By 2050, the world
will produce 13.1 billion tonnes of waste annually, a fifth more than today.
- FOOD: One person in seven suffers
from malnourishment. Demand for food will increase by some 70 percent by 2050,
which will lead to a nearly 20 percent increase in global agricultural water
consumption. Between 2000 and 2010, 203 million hectares (500 million acres) of
land were transferred to foreign control, especially to China, petro-economies
in the Gulf and rich countries eager for food security and biofuels. Two-thirds
of the transactions were in Africa and 14 percent in Asia.
- TAXES AND SUBSIDIES: Subsidies for
fossil fuels amounted to $312 billion in 2009. A tax of 0.005 percent on foreign
exchange trading could raise $40 billion a year in additional aid for poor
countries, which in 2010 stood at $130 billion.
