Rio Summit: The world in figures

Jun 11, 2012

Following is a snapshot of the world ahead of the UN's June 20-22 Rio Summit on sustainable development.

- 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 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 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 . For the first time in 20 years, the proportion of Africans living in 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 and nearly one in 10 has yet to gain access to "improved" , as defined under the UN's 2015 development goals. 1.4 billion people have no mains electricity.

- : Emissions of man-made 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 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 , which in 2010 stood at $130 billion.

It's getting about time for US to really participate in stuff like the Kyoto Protocol instead of just signing it and then buggering off. The holy meat and oil consumption has to give, it consumes to much resources. We westerners have the knowledge, wealth and education to do something about it and while we're at it, decrease our dependance on oil-producing countries too.

That is a pretty disturbing ecological footprint....every time I see it. I believe it has been mentioned a few times.
