An Effective System of Mass Extinction

Posted by edro on August 21, 2008

The Exponential Growth Economy is Committing Life to Extinction

Yet, our top scientists want to preserve the economic system, instead of sustaining life on Earth!

Instead of urging an immediate end to the exponential growth economy and demanding a zero-growth, low carbon, waste-free oikonomia for managing the environment, welfare of humans and other living species, and a system of ‘housekeeping’ for the planet’s natural resources to sustain life on Earth, the country’s top scientists are looking for ways of serving the economic Titanic.

  • US CO2 Emissions (2007) : 6,825.733 MMT [based on CDIAC data updated by MSRB/CASF]
  • Virtual CO2 content of US dollar (2007) : 494 g (The average amount of CO2 produced each time a dollar was paid or received in 2007. SEE: How Much Carbon Dioxide Does Your Money Make?)

The Collapse Engine Revving UP!

Posted by msrb on August 18, 2008

The problems?

  • Water scarcity. About 3 billion people are affected by water scarcity caused by diminishing reserves of freshwater (excessive use), climate change (drought, extreme climatic events, vanishing snow caps…)
  • Excessive volumes of wastewater produced by growing urban population
  • Increased demand for crops to feed growing urban population

The “Quick Fix!”

Irrigating urban agricultural land with untreated wastewater!

A possible outcome:

Spread of pandemic diseases leading to large scale collapse

A new 53-city study conducted by the International Water Management Institute (IWMI) reveals that about 80 percent of the cities studied use untreated or partially diluted wastewater for agriculture. At least 50 percent of the urban agricultural land in those cities is irrigated with raw or diluted wastewater.

“Irrigating with wastewater isn’t a rare practice limited to a few of the poorest countries. It’s a widespread phenomenon, occurring on 20 million hectares across the developing world, especially in Asian countries, like China, India and Vietnam, but also around nearly every city of sub-Saharan Africa and in many Latin American cities as well,” said IWMI researcher Liqa Raschid-Sally.

“It’s a widespread phenomenon, occurring on 20 million hectares (50 million acres) across the developing world, especially in Asian countries, like China, India and Vietnam, but also around nearly every city of sub-Saharan Africa and in many Latin American cities as well.”

Wastewater is most commonly used to produce vegetables and cereals, especially rice, pose a health threat to the farmers as well as the consumers.

“The negative and positive implications of wastewater agriculture have only recently received attention. This study offers the first comprehensive, cross-country analysis of the conditions that account for the practice and the difficult tradeoffs that arise from it,” said Colin Chartres, director general of IWMI.

About 200,000 people in Accra, 10 percent of the urban population of Ghana’s capital city, consume vegetables produced on just 100 hectares of urban agricultural land, which is irrigated with wastewater, according to the IWMI report. “That gives you an idea of the large potential of wastewater agriculture for both helping and hurting great numbers of urban consumers.” Raschid-Sally said.

“And it isn’t just affluent consumers of exotic vegetables whose welfare is at stake. Poor consumers of inexpensive street food also depend on urban agriculture.” She reported.

How Much CO2 Are You Producing?

Posted by edro on August 8, 2008

Original Entry: World CO2 Emissions

World Anthropogenic CO2 Emissions from Fossil Fuel Consumption (including Flaring) Cement Production and Tropical Deforestation

CO2 This Year ( From 1-1-2008 to 8-8-2008 )
23,803.61 MMT CO2

CO2 Total 2007
38,058.66 MMT CO2

Anthropogenic CO2 Total (1750 – Today)
1,358,931.31 MMT CO2

Total atmospheric CO2

3,008,879.36 MMT [3,008.88GT]

How much CO2 are YOU producing?

Each dollar you earn or spend produces 584 g of CO2. [See Carbon Footprint of Your Dollar]

How much CO2 was there before?

Measurements of CO2 levels in Ice cores collected in Antarctica and Greenland indicate that the preindustrial carbon dioxide level was 278 ppm. Between 1000 and 1800 A.D. that level varied by no more than 7 ppm.

What about human activities?

The CO2 levels have now reached 386 ppm, which means human activities have increased the concentration of atmospheric CO2 by 109 ppm or 39 percent.

Notes:
MMT: Million Metric Tons
GT: Gigatons (billion tons)
Sources: CASF/MSRB; CDIAC; Netherlands Environmental Assessment Agency; Earth Systems Research Laboratory; Mauna Loa CO2 monthly mean data.

The following data were used to calculate the total mass of atmospheric CO2 :
1. Mass of dry air: 5.1352 × 1018 kg
2. The mean molar mass of air: 28.9625 g/mol.
3. Molar mass of CO2: 44.0095 g/mol.
4. Mauna Loa CO2 monthly mean data: 385.60ppmv

[Note: On various websites reporting the carbon dioxide emissions since 1750 the cumulative amount varies from about 1.3 – 1.8 trillion tons. On one website the amount is published once as 1.36 trillion tons and again as 1.71 trillion tons of CO2 on separate pages. Understandably, no sources are quoted. ]

Carbon Footprint of Your Dollar

How Much Carbon Dioxide Does Your Money Make?

Definitions

GDP is gross domestic product at purchaser prices. It is the sum of the gross value added by all resident producers in the economy plus any product taxes and minus any subsidies not included in the value of the products. It is calculated without deductions for depreciation of fabricated assets or for depletion and degradation of natural resources. PPP GDP is gross domestic product converted to international dollars using purchasing power parity rates. An international dollar has the same purchasing power over GDP as a U.S. dollar has in the United States. (Source: World bank)

GDP = consumption + gross investment + government spending + net exports

United States one dollar bill (obverse).

.

GNI (gross national income) is gross domestic product (GDP) plus net receipts of primary income (employee compensation and investment income) from abroad. GDP is the sum of value added by all resident producers plus any product taxes (less subsidies) not included in the valuation of output. (World Bank)

GNI per capita is gross national income divided by midyear population. PPP GNI is gross national income converted to international dollars using purchasing power parity rates. An international dollar has the same purchasing power over GNI as a U.S. dollar has in the United States. (World Bank)

World Population and GDP figures

World population 2007 (World Bank) : 6.61billion
GNI per capita 2007 (PPP) : 9,816 (International Dollars)
World GNI : 64.9 trillion (International Dollars)
World GDP: 65.17 trillion (International Dollars)

[PPP is purchasing power parity; an international dollar has the same purchasing power over GNI or GDP as a U.S. dollar has in the United States.]

Energy and GDP

To create the above economic figures [GNI and GDP,] the world economies consumed about 531 exajoules [503 quads] of energy in 2007. [Sources: CASF and MSRB]

To produce a GDP of 65.17 trillion (International Dollars), the world economies emitted about 10.38 billion metric tons of carbon [~38.06 billion tons of CO2.] That is, for every dollar paid (or received) each time in 2007 an average of about 160 grams of carbon, or 584 g of CO2 were released to the environment! [Sources: CASF and MSRB]

Notes:
1. 1kg (1,000g) is about 2.21lb [1 lb ~ 453.6g]
2. The above figure of 584g of CO2/GDP dollar is a global average. In the US the pollution figure is 578g of CO2/GDP dollar. In China the CO2 amount per GDP dollar of economic activity rises to 1,282g – about 2.2 times the global average of CO2/GDP dollar. [Updated Sept. 2008 ]
