THE POPULATION PROBLEM


Website for this image

If you are an Orang Utan, whose land is being taken over by humans, you may think that there are just too many people in the world.

The world's population has been growing rather rapidly in recent years and this has caused some problems.

The population of the United States is expected to increase by 44% from 2008 to 2050.[52]

Overpopulation - Wikipedia

The current population of the USA is 312.8 million people.

In a study entitled Food, Land, Population and the U.S. Economy, Professor David Pimentel, estimated the maximum U.S. population for a sustainable economy at 200 million. [73]

Sustainable economy?

We are thinking about traffic jams, air pollution, farmland concreted over, endless wars to seize valuable resources...



"The technological optimists are probably correct in claiming that overall world food production can be increased substantially over the next few decades...

"However, the environmental cost of what Paul R. and Anne H. Ehrlich describe as 'turning the Earth into a giant human feedlot' could be severe.

"A large expansion of agriculture to provide growing populations with improved diets is likely to lead to further deforestation, loss of speciessoil erosion, and pollution from pesticides and fertilizer runoff as farming intensifies and new land is brought into production."[117]

The fertility rate is going up. The best of all possible worlds? - The Economist...

The 'theory of demographic transition' held that, after the standard of living and life expectancy increase, family sizes and birth rates decline.

However, as new data has become available, it has been observed that after a certain level of development the fertility increases again.[66]



My friend Mardi was living in a village in West Java. 

The surrounding area is fertile and good for growing rice.

But, as the population rose, there was no longer enough land for everyone.

Mardi could have moved his family to a remote part of the island of Kalimantan. 

But he would have arrived in an area with poor soils and lots of hostile Dayaks.

Life would have been no easier.


Jakarta

Instead, Mardi moved his family to a heavily polluted slum in Jakarta, a city of 25 million people and heavy traffic jams..

The floods in the slum worsened each year, partly because so many trees in the region have been cut down and so much land has been concreted over.

Eventually the city authorities demolished the slum and Mardi had to return to his overcrowded village.

Mardi does use birth control and has only two children.

His sister has five children.

Worldwide, nearly 40% of pregnancies are unintended (some 80 million unintended pregnancies each year).[225]

One suggested solution is for population growth to be slowed quickly by investing heavily in female literacy and family planning services.[188]


Even very sparsely populated areas can be overpopulated if the area has a meager or non-existent capability to sustain life (e.g. a desert)

Overpopulation - Wikipedia

Estimates for the carrying capacity of the planet vary between 4 billion and 16 billion.

You will read below why the 16 billion figure is nonsense.

The population is expected to reach between 8 and 10.5 billion between the year 2040[7][8] and 2050.[9] 

Steve Jones, head of the biology department at University College London, has said, "Humans are 10,000 times more common than we should be".[11] 

The InterAcademy Panel Statement on Population Growth has stated that many environmental problems, such as pollution, are aggravated by the population expansion.[12] 

Other problems associated with overpopulation include consumption of natural resources faster than the rate of regeneration.


A poor neighbourhood in Cairo.

The good news is that, in some parts of the world, the rate of population growth has been declining since the 1980s.

But, the world's population is still rising, even if not quite so fast.

And the 'theory of demographic transition' may have to be adjusted.

As new data has become available, it has been observed that after a certain level of development the fertility increases again.[66]

Some people who have become richer are now producing larger families!



Indonesia's population grew from 97 million in 1961 to 237.6 million in 2010,[38][39] a 145% increase in 49 years.

In India, the population grew from 361.1 million people in 1951 to just over 1.2 billion by 2011,[40][41] a 235% increase in 60 years.

The population of Chad grew from 6,279,921 in 1993 to 10,329,208 in 2009.[42]



According to the United Nations' World Population Prospects report:[49] the world population is currently growing by approximately 74 million people per year.

During 2005–2050, the net number of international migrants to more developed regions is projected to be 98 million.


Urban areas with at least one million inhabitants in 2006. 

If current trends continue, the world's urban population will double every 38 years, according to researchers. The UN forecasts that today's urban population of 3.2 billion will rise to nearly 5 billion by 2030, when three out of five people will live in cities.[55]

One billion people, one-sixth of the world's population, or one-third of urban population, now live in shanty towns,[57] which are seen as "breeding grounds" for social problems such as crime, drug addiction, alcoholism, poverty and unemployment.

In 2000, there were 18 megacities-conurbations such as Tokyo, Seoul, Mexico City, Mumbai, São Paulo and New York City – that have populations in excess of 10 million inhabitants. Greater Tokyo already has 35 million.[59]

Jakarta (24.9 million people), Dhaka (25 million), Karachi (26.5 million), Shanghai (27 million) and Mumbai (33 million).[60] Lagos 15 million.

Overpopulation - Wikipedia


United Nation's population projections by location

Does it help if women have more power?

One version of 'demographic transition' is proposed by anthropologist Virginia Abernethy in her book Population Politics.

She claims that population rises decrease primarily in nations where women enjoy a higher status (see Fertility-opportunity theory).

In strongly patriarchal nations, where she claims women enjoy few special rights, a high standard of living tends to result in population growth.

"Demographic entrapment" is an idea developed by Maurice King, Honorary Research Fellow at the University of Leeds.

He writes that that this phenomenon occurs when a country has a population larger than its carrying capacity, no possibility of migration, and exports too little to be able to import food. This will cause starvation.

He claims that for example many sub-Saharan nations are or will become stuck in demographic entrapment, instead of having a demographic transition.[67]

Overpopulation - Wikipedia


World energy consumption & predictions, 1970–2025.

Problems associated with over-population include:

Deforestation, loss of ecosystems, increased noise air and water pollution, soil exhaustion, desertification, antibiotic resistant diseases, increased crime, starvation...


India, 1972

"Virgin stocks of several metals appear inadequate to sustain the modern 'developed world' quality of life for all of Earth's people under contemporary technology".[115]

A study by the United Nations Environment Programme (UNEP) called the Global Environment Outlook[125] "found that human consumption had far outstripped available resources. Each person on Earth now requires a third more land to supply his or her needs than the planet can supply."

Fresh water supplies, on which agriculture depends, are running low worldwide.[128][129]

"Desalinated water may be a solution for some water-stress regions, but not for places that are poor, deep in the interior of a continent, or at high elevation. Unfortunately, that includes some of the places with biggest water problems."[137]


Food per person increased during the 1961–2005 period.

Some scientists argue that there is enough food to support the world population,[143][144] but critics dispute this, particularly if sustainability is taken into account.[145]

However, the figures for 2007 show an actual increase in absolute numbers of undernourished people in the world, 923 million in 2007 versus 832 million in 1995.[149].

The more recent FAO estimates point to an even more dramatic increase, to 1.02 billion in 2009.[150]

The proportion of the world's population living on less than $1 per day has gone down, but the figures have not been adjusted for inflation, and are thus misleading.[204]

A working class American may now have a higher wage than in the 1980s, but he is not necessarily better off, because prices have risen.


Percentage of population suffering from malnutrition by country, according to United Nations statistics. Red = most malnourished. Green = least malnourished.

Food riots have recently taken place in many countries across the world.[166][167][168]

Growing populations, falling energy sources and food shortages will create the "perfect storm" by 2030, according to the UK government chief scientist.

He said food reserves are at a 50-year low but the world requires 50% more energy, food and water by 2030.[172][173]

The world will have to produce 70% more food by 2050 to feed a projected extra 2.3 billion people, the United Nations' Food and Agriculture Organisation (FAO) warned.[174]

In Africa, if current trends of soil degradation and population growth continue, the continent might be able to feed just 25% of its population by 2025, according to UNU's Ghana-based Institute for Natural Resources in Africa.[175]

In sub-Saharan Africa, the number of malnourished people grew to 203.5 million people in 2000–02 from 170.4 million 10 years earlier says The State of Food Insecurity in the World report.

In 2001, 46.4% of people in sub-Saharan Africa were living in extreme poverty.[176]


Bangladesh

Recent data indicate China's grain production peaked in the mid 1990s, due to over-extraction of groundwater in the North China plain.[178]

Japan may face a food crisis, believes a senior government adviser.[179]

The water tables are falling in scores of countries (including Northern China, the US, and India).

Even with the over-pumping of its aquifers, China has developed a grain deficit.  Desalination is also considered a viable and effective solution to the problem of water shortages.[134][135]

After China and India, there is a second tier of smaller countries with large water deficits – Algeria, Egypt, Iran, Mexico, and Pakistan.



The World Resources Institute states that "Agriculture has displaced one-third of temperate and tropical forests and one-quarter of natural grasslands."[189][190]

"Usable land may become less useful through salinizationdeforestationdesertificationerosion, and urban sprawl."

The United Nations indicates that about 850 million people are malnourished or starving,[100] and 1.1 billion people do not have access to safe drinking water.[82]

Some argue that the Earth may support 6 billion people, but, only if many live in misery.

The proportion of the world's population living on less than $1 per day has gone down, but the figures have not been adjusted for inflation, and are thus misleading.[204]

The UN Human Development Report of 1997 states: "During the last 15–20 years, in more than 100 developing countries... the reductions in standard of living have been deeper and more long-lasting than what was seen in the industrialised countries during the depression in the 1930s."


Wealth per capita graphed against fertility rate.

Environmental author Jeremy Rifkin has said that "our burgeoning population and urban way of life have been purchased at the expense of vast ecosystems and habitats. ... It's no accident that as we celebrate the urbanization of the world, we are quickly approaching another historic watershed: the disappearance of the wild."[208]

Says Peter Raven, in AAAS Atlas of Population and Environment, " During a remarkably short period of time, we have lost a quarter of the world's topsoil and a fifth of its agricultural land, altered the composition of the atmosphere profoundly, and destroyed a major proportion of our forests and other natural habitats without replacing them.

"Worst of all, we have driven the rate of biological extinction, the permanent loss of species, up several hundred times beyond its historical levels, and are threatened with the loss of a majority of all species by the end of the 21st century."

The Worldwatch Institute said: The world's ecological capacity is simply insufficient to satisfy the ambitions of China, India, Japan, Europe and the United States as well as the aspirations of the rest of the world in a sustainable way [209]

It said that if China and India were to consume as much resources per capita as the United States or Japan in 2030 together they would require a full planet Earth to meet their needs.[210]

In the long term these effects can lead to increased conflict.

The last Bali 'big cat'.

Worldwide, nearly 40% of pregnancies are unintended (some 80 million unintended pregnancies each year).[225]

An estimated 350 million women in the poorest countries of the world either did not want their last child, do not want another child or want to space their pregnancies, but they lack access to information, affordable means and services to determine the size and spacing of their families.

One option is to focus on education about overpopulation, family planning, and birth control methods, and to make birth-control devices like male/female condomspills and intrauterine devices easily available.

MAATHAI VERSUS THE IMF AND WORLD BANK


Professor Wangari Maathai (Nobel laureate and environment‎alist) was born in the central highlands of Kenya in 1940.

Back in the 1940s, her small village had clean water, rich soils, rich forests and plenty of food.

"It was heaven. We wanted for nothing," she said.

"Now the forests have come down, the land has been turned to commercial farming, the tea plantations keep everyone poor, and the economic system does not allow people to appreciate the beauty of where they live."


Maathai was educated by Catholic nuns. (environment‎)

Maathai said: "After my education by the nuns, I emerged as a person who believed that society is inherently good and that people generally act for the best."

Maathai won a scholarship to study in the US, as part of the 'Kennedy airlift' in which 300 Kenyans - including Barack Obama’s father - were chosen to study at American universities in 1960.

After further study in Germany, she returned to a newly independent Kenya in 1966.

Her early work as a vet took her to some of Kenya's poorest areas.

She saw first-hand the damage that was being done to the environment.

In 1977, she set up the Green Belt movement.

She became critical of politicians in Kenya, the World Bank, the IMF, Britain and other former colonial powers.

Before the 1990s, the Mau forest (above) was a protected area. "But then senior officials in President Daniel arap Moi's government grabbed large plots of the highly fertile land for themselves." Website for this image

What began as a few women planting trees became a network of 600 community groups.

They looked after 6,000 tree nurseries, which were often supervised by disabled and mentally ill people in the villages.

By 2004, more than 30 million trees had been planted, and the movement had branches in 30 countries.

In Kenya, the Green Belt movement has become an agricultural advice service, a community regeneration project and a job-creation plan.

In the early 1990s, Maathai set up Mazingira, the Kenyan Green Party.

Maathai became a junior environment minister between January 2003 and November 2005.

She died in September 2011. (Nobel laureate and environment‎alist)

THE ENVIRONMENT AS A WEAPON

General Zinni, 'the Godfather'.

Does the US military use the environment as a weapon?

Could the US military damage the environments of Pakistan, Somalia, Yemen or parts of Afghanistan?

General Anthony Zinni is a former chief of U.S. Central Command.

He has been talking to top people in Washington about how the degradation of the environment and declining natural resources affect security. (Environment key to U.S. security: Congress briefing)

According to Zini:

"We can't just send in the Army and the Marines and the Air Force and the Navy to resolve these problems, and they can't all be security problems...

"Whether it is climate change, whether it is disruption of the environment in other ways ... we're going to see more failed and incapable states."

Zinni referred to:

Depletion of fish stocks off Somalia,

The drop in water and oil resources in Yemen,

Droughts in Afghanistan

And scarce and polluted water in Pakistan.

Could some of these problems be man-made? (WEATHER WEAPONS - PAKISTAN, INDIA, VENEZUELA, RUSS...)

Lieutenant Colonel Shannon Beebe, an Africa analyst, compared the traditional threats to security with those posed by environmental and natural resource problems.

Beebe is quoted as saying: "You think we're going to continue to face state-based threats?

"Might I remind you of the two greatest attacks on the United States at the beginning of the 21st century, and neither of those was from a state-based threat: 911 and Hurricane Katrina... (Did Bush government break the levees?)

"When you talk to Africans ... ministers and chiefs of defense, they will talk to you in terms of security as food, as environmental degradation, natural disasters, environmental shocks."

~~

Remember Katrina?

Did the Bush government break the levees?

GDN01 writes that a good friend with much family in New Orleans said "I'll tell you the worst thing I've heard and I heard it from my mother."

She said she heard several blasts - big booms - right before the levees broke.

"Several blasts and then all the water came pouring in."

Several people have said this same thing.

This is the story going round from the people who were there.

NORWAY'S ONE BILLION


In May 2010, Indonesia's president Yudhoyono announced a two-year ban on turning virgin forests and peat lands into plantations. (Indonesia announces plan to protect forests, peatlands)

Norwegian Prime Minister Jens Stoltenberg says Norway will give $1 billion to Indonesia to help with the effort to reduce deforestation.


In Indonesia there has been much deforestation and much destruction of peatlands.

This has meant:

1. The extinction of species

2. Desertification

3. Poor people losing their land.

Indonesia burns forests and peatlands to make way for palm oil plantations.

The resulting fires makes Indonesia one of the world's largest producers of greenhouse gases.

CLIMATE: CUBA, SCOTLAND, ETHIOPIA, INDONESIA...


1. Climate Change?

"Climate change is now blamed for just about everything...

"Famines and drought have a long history in Ethiopia and development experts have traditionally blamed poor governance and the state’s exclusive, and inefficient, hold on farmland for that.

"But, with the possibility of another famine looming, Meles Zenawi, the country’s prime minister for the past 18 years, has preferred to blame climate change for his country’s woes." - The Economics and Politics of Climate Change

2. Trees?

"85 % of Sumatra's forests are gone." - Rainforests turned into smoldering ruins

3. Big corporations?

"Most rainforests are cleared ... for its timber value and then are followed by farming and ranching operations, even by world giants like Mitsubishi Corporation, Georgia Pacific, Texaco and Unocal."

"Experts agree that by leaving the rainforests intact and harvesting it's many nuts, fruits, oil-producing plants, and medicinal plants, the rainforest has more economic value than if they were cut down to make grazing land for cattle or for timber.

"The latest statistics show that rainforest land converted to cattle operations yields the land owner $60 per acre and if timber is harvested, the land is worth $400 per acre.

"However, if these renewable and sustainable resources are harvested, the land will yield the land owner $2,400 per acre." Rainforest Facts


4. Who to copy?

There is a dispute about global warming.

But, most people agree about the need to look after the environment.

Too many trees are being cut down, too much air is polluted and too many creatures are dying out.

A new report from the charity Oxfam says the world should copy Scotland in environmental policy.

One of Obama’s top advisers says the world must follow Scotland's lead in environmental policy.

Obama's climate adviser praises Scotland

Professor Diana Liverman, the Oxford scientist and presidential adviser, backs the Oxfam report that singles out Scotland as an example for the rest of the world to follow.

Malcolm Fleming, Oxfam's Scottish campaigns manager, said: "Scotland is already leading the world ... with targets guided by science rather than political expediency."

The Oxfam report states 375m people will likely be affected by climate-related disasters by 2015, and that 200m people may need to migrate each year by 2050 because of hunger, environmental degradation and loss of land.

Scotland is expected to provide around 25% of Europe's ALTERNATIVE energy.

Scotland's SNP government is OPPOSED to nuclear energy.


Cuba by Henryk Kotowski

5. We should copy Cuba?

A study of 93 nations has found that only one nation - Cuba - is developing sustainably.

"The wholesale plunder of the planet’s natural resources has brought into sharp focus the necessity for some kind of global (and globally enforceable) regulation of what’s left of the planet’s precious cargo of life.

"But can capitalism undertake such a task?...

"There is a certain irony in the fact that Cuba, through force of circumstance, has had to embark on the construction of a sustainable economy." - Marx, the First Real Globalist

What is the problem with regard to Population and Growth?

There appears to be a problem of over-population - Once it Starts ....

There appears to be an ecological crisis - It's Over

We need to think about over-population - The Crisis of Overpopulation

Image:CO2 responsibility 1950-2000.svg

Why must we all copy Cuba?

Cubans have high life expectancy and literacy. Cubans do not use much oil.

A study of 93 nations has found that only one nation - Cuba - is developing sustainably.

Cuba is the only nation which:

(1) provides a decent standard of living for its people and

(2) does not consume more than its fair share of the world's resources.


New Scientist (World failing on sustainable development - earth - 03 October 2007 ... / Cuba Flies Lone Flag for Sustainability - Indymedia Ireland) provides the details:

"An international team led by Mathis Wackernagel of the Global Footprint Network looked at how the living conditions and ecological footprints of 93 nations have changed in the last 30 years.

"They used the ecological footprint (EF) index, a tool devised in 1993 by Wackernagel and William Rees, his PhD supervisor at the University of British Columbia, Canada. EF quantifies the area of land required to provide the infrastructure used by a person or a nation, the food and goods they consume, and to reabsorb the waste they produce, using available technology."

We should not copy the poorest countries in Africa because, although they do not consume more than their fair share of resources, they do not have a decent standard of living for all their people.

Under no circumstances should we copy the USA or the United Arab Emirates, because they consume much more than their fair share of resources.

COPENHAGEN PSYOP?

In Bhopal, in India, a Union Carbide plant, which manufactured pesticides, leaked deadly methyl isocyanate gas during the night of 3 December, 1984. 20,000 people are reported to have died.

There is horrid air pollution in the Mediterranean.

Too many trees are being cut down in Indonesia.

Fish stocks are at risk.

Big US corporations are damaging the planet.

The Pentagon is damaging the planet.

There is to be a summit in Copenhagen.

isiria.wordpress.com/.../

Michel Chossudovsky, at Global Research, on 30 November 2009 wrote an article entitled: Global Warming: "Fixing the Climate Data around the Policy"

Among the points made:

1. Prior to the United Nations Climate Change Conference in Copenhagen, key decisions have already been made at the World Business Summit on Climate Change (WBSCC) held in May 2009.

A summary report has been produced by PricewaterhouseCoopers LLP, on behalf the corporate bosses.

This report has very little to do with environmental protection.

It's about making money.

2. The Copenhagen Summit will not mention the US-NATO led wars and their environmental consequences.



3. The Copenhagen Summit will not mention "weather warfare" or "environmental modification techniques" and climatic warfare.

4. The Copenhagen Summit will divert attention away from the devastation caused by big corporations and by the Pentagon.

5. The carbon trading system is a multibillion money-making operation aimed at helping the money-men.

6. There are indications that the ideas and figures on temperature and greenhouse gas emissions including CO2 have been adjusted and shaped to fit the agenda of the UN Panel on Climate Change.

GROSS NATIONAL HAPPINESS


What is GNH?

Mirka Knaster tells us (Greater Good Magazine Bhutan at a Crossroads By Mirkan Knaster):

Bhutan's Gross National Happiness is measured by:

1. How well the natural environment is supporting the people.

2. The extent to which communities and families are intact and thriving, not just financially but also culturally.

3. Its citizens' reports on their own levels of happiness.

"The Bhutanese, as well as many outside observers, argue that the secret of their happiness lies in the security of their community, kinship, and family relationships, and in a self-sufficient lifestyle.

"And their Buddhist spiritual tradition, which considers craving the root cause of unhappiness, guides their daily life.

"Its commitment to priorities beyond the almighty dollar is often cited as a main reason why happiness is so pervasive in Bhutan—and it is why the country has been celebrated by commentators around the world."


Photo of Bhutan by Stephen Shephard


Journalist Eric Weiner, in his 2008 book, The Geography of Bliss, explains:

"They do things that don't make economic sense. In Bhutan, what's on the inside is often more impressive than what's on the outside."

According to Weiner (Be like Bhutan - Los Angeles Times):

"What do the following have in common?

"The war in Iraq. Sales of cigarettes...

"The answer: They all contribute to our nation's gross domestic product, or GDP, and therefore are all considered 'good,' at least in the dismal eyes of economists...

"Bhutan, a tiny Himalayan nation, has invented a radically new metric: Gross National Happiness...

"While other developing countries have sold off their natural resources to the highest bidder, Bhutan has hardly touched its timber and minerals...

"Many Bhutanese are willing to forsake money for happiness; for a slower, more human pace of life. The vast majority of Bhutanese who study abroad, for instance, return to their homeland, where they earn a fraction of what they could earn in the West."

Food Price Crisis

Photo by Walter Siegmund

On 15 May 2009, the BBC World Service index of retail food prices showed that basic food prices worldwide have gone up 8% in the last 10 months. (Food prices vary but crisis remains)

The index is based on eight cities, including Washington, Nairobi and Buenos Aires.

In Nairobi, in Kenya, where many people earn only one US dollar a day, there was a rise of almost 50% in the price of food in the last 10 months.

The United Nations' Food and Agriculture Organisation index shows food prices nearly 50% higher than in 2003. The price of cereals is up 80% since 2003.

ActionAid International predicts that about 17 million people in Kenya are now in danger of starvation.




"Agricultural yields in Africa have... fallen in some cases by up to 50 per cent as a result of invasive pests, land degradation, erosion, drought and climate change, according to the report, released .... by the UN Environment Programme...

"Reversing environmental degradation and 'investing in ... forests, soils and water bodies is one part of the ... solution...The other key is managing them and the food chain in far more efficient ways.'

"Over half of food produced worldwide is lost, wasted or discarded as a result of inefficiency..."

Epidemic of Extinctions


The Living Planet Index, produced by WWF, the Zoological Society of London (ZSL) and the Global Footprint Network, says:

1. land species have declined by 25 per cent,

2. marine life by 28 per cent,

3. freshwater species by 29 per cent.

(See: An Epidemic of Extinctions: Decimation of Life on Earth ...)

The causes are reported to be:

1. climate change,

2. pollution,

3. the destruction of animals' natural habitat,

4. the spread of invasive species,

5. the overexploitation of species.

Jonathan Loh, editor of the report, said the sharp fall was "completely unprecedented in terms of human history. You'd have to go back to the extinction of the dinosaurs to see a decline as rapid as this."

Scientists say the current extinction rate is now up to 10,000 times faster than what has historically been recorded as normal.

According to James Leape, director general of WWF:

"Reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease and where water is in irregular or short supply.

"No one can escape the impact of biodiversity loss because reduced global diversity translates quite clearly into fewer new medicines, greater vulnerability to natural disasters and greater effects from global warming. The industrialised world needs to be supporting the global effort to achieve these targets, not just in their own territories where a lot of biodiversity has already been lost, but also globally."

Climate change due to solar radiation and human emissions


When we look at climate change we have to look at changes in

(1) solar radiation

(2) human emissions of CO2.

Professor Peter Cox, a climate expert at the UK's University of Exeter, has studied the Little Ice Age, 400 years ago (Geographical Research letters Vol 33; New Scientist 22 March 2008). (Rising temperatures bring their own CO2 / Grains of Sand)

Cox has noted that:

This Little Ice Age began with reduced solar radiation due to a variation in sunspots.

When it gets colder, the oceans, and eventually the land, absorb more CO2.

So CO2 levels went down after the Little Ice Age began.

Cox notes that when temperatures rise, due to increased solar radiation, there is eventually a rise in CO2 levels.

The oceans and the land absorb less CO2

The temperature rise comes first, and is followed by the rise in CO2.

Cox believes that what we have now, in the present time, is both a rise in CO2 levels due to increased solar radiation and an increase due to human-made emissions.

Things are worse than we thought, argues Cox.

According to Cox (Rising temperatures bring their own CO2):

"There seems to be a change of about 40 parts per million (ppm) in CO2 levels for every 1 °C change in temperature.

"Since further global warming is inevitable in the near future, it means we're heading for big natural increases in CO2 on top of human-made emissions.

"This extra increase will boost global warming in the coming century to about 50 per cent above mainstream climate projections, says Cox, because they only include the effect of CO2 on temperature, and not temperature's effect on CO2.

"The system turns out to be more sensitive than we thought. If we get 4 °C of warming in the coming century, that by itself will raise CO2 levels by an extra 160 ppm."

Pre-industrial levels of CO 2 were 270 ppm

Current levels of CO2 are 380 ppm

Many scientists believe there will be a devastating global climate at 450 ppm.

We MUST all copy Cuba

Why must we all copy Cuba?

Cubans have high life expectancy and literacy. Cubans do not use much oil.

A study of 93 nations has found that only one nation - Cuba - is developing sustainably.

Cuba is the only nation which:

(1) provides a decent standard of living for its people and

(2) does not consume more than its fair share of the world's resources.

New Scientist (World failing on sustainable development - earth - 03 October 2007 ... / Cuba Flies Lone Flag for Sustainability - Indymedia Ireland) provides the details:

"An international team led by Mathis Wackernagel of the Global Footprint Network looked at how the living conditions and ecological footprints of 93 nations have changed in the last 30 years.

"They used the ecological footprint (EF) index, a tool devised in 1993 by Wackernagel and William Rees, his PhD supervisor at the University of British Columbia, Canada. EF quantifies the area of land required to provide the infrastructure used by a person or a nation, the food and goods they consume, and to reabsorb the waste they produce, using available technology."

We should not copy the poorest countries in Africa because, although they do not consume more than their fair share of resources, they do not have a decent standard of living for all their people.

Under no circumstances should we copy the USA or the United Arab Emirates, because they consume much more than their fair share of resources.
