Help Wanted: 27 Planet Earths
This story was featured on the IPS wire and on the Al Jazeera network in 2011. It shows that national parks, conservation and protected areas do not and cannot halt the decline in biodiversity that is humanity’s life support system. It is hopeless without addressing the root causes: too many of us, taking too much and having too big of an impact. On our present course we’ll need 27 planet Earths by 2050 experts conclude. — Stephen

Protecting bits of nature here and there will not prevent humanity from losing our life support system. Even if areas dedicated to conserving plants, animals, and other species that provide Earth’s life support system increased tenfold, it would not be enough without dealing with the big issues of the 21st century: population, overconsumption and inefficient resource use.
Without dealing with those big issues, humanity will need 27 planet Earths by 2050, a new study estimates.
The size and number of protected areas on land and sea has increased dramatically since the 1980s, now totaling over 100,000 in number and covering 17 million square kilometres of land and two million square kilometres of oceans, a new study reported Thursday.

But impressive as those numbers look, all indicators reveal species going extinct faster than ever before, despite all the additions of new parks, reserves and other conservation measures, according to the studypublished in the journal Marine Ecology Progress Series.
“It is amazing to me that we haven’t dealt with this failure of protected areas to slow biodiversity losses,” said lead author Camilo Mora of University of Hawaii at Manoa.
“We were surprised the evidence from the past 30 years was so clear,” Mora told IPS. Read the rest of this entry »

Oceans Filled with Plastic Trash – Changing Marine Ecology
Tiny bits of plastic now found throughout the world’s oceans
Ban single-use plastic: bags, bottles, cups etc, scientists say
By Stephen Leahy
UXBRIDGE, Canada, May 10, 2012 (IPS)
Plastic trash is altering the very ecology of the world’s oceans. Insects called “sea skaters”, a relative of pond water striders, are now laying their eggs on the abundant fingernail-sized pieces of plastic floating in the middle of the North Pacific Ocean instead of relying on a passing seabird feather or bit of driftwood.
With an average of 10 bits of plastic per cubic metre of seawater, there are now plenty of places for sea skaters to lay eggs in a remote region known as the North Pacific Subtropical Gyre, 1,500 kilometres west of North America. Not surprisingly, egg densities have soared, a new study has found.
“We’re seeing changes in this marine insect that can be directly attributed to the plastic,” says Miriam Goldstein, study co-author and graduate student at the Scripps Institution of Oceanography at UC San Diego.
This is the first proof that plastics in the open ocean are affecting marine invertebrates (animals without a backbone), which will have consequences for the entire marine food web.
“We simply don’t have the data to know what those consequences will be. It is a very remote region of the ocean, hard to get to and expensive to conduct research,” Goldstein told IPS.
The North Pacific Gyre is one of five large systems of rotating currents in the world’s oceans. It has become better known in recent years as the “Great Pacific Garbage Patch”. It has at least 100 times more plastic today than it did in 1972, according to the study published this week in the journal Biology Letters.
“There were no hard surfaces before in the North Pacific Gyre other than the occasional feather and piece of wood,” says Miriam Goldstein, study co-author and a graduate student at the Scripps Institution of Oceanography at UC San Diego.
“The ocean looks pretty normal out there in the gyre. There is no floating island of trash as some people imagine,” Goldstein told IPS. Read the rest of this entry »
Ocean Acidification Leaves Mollusks Naked and Confused
By Stephen Leahy
When the carbon dioxide absorbed by the oceans dissolves in seawater, carbonic acid is formed and calcium carbonate, vital for the formation of the skeletons and shells of many marine organisms, becomes scarcer.
MONTEREY, California, Oct 2 2012 (IPS) -
Climate change will ruin Chilean sea snails’ ability to sniff out and avoid their archenemy, a predatory crab, according to Chilean scientists who presented their findings at an international science symposium here.
Researchers from Australia also revealed that as the oceans become more and more acidic, some fish become hyperactive and confused, and move towards their predators instead of trying to escape.
“The conditions in oceans are changing 100 times faster than at any time in the past,” said Jean-Pierre Gattuso, a marine biologist with CNRS-INSU and the Laboratoire d’Océanographie de Villefranche in France.
Climate change is making oceans warmer and more acidic. “We are beginning to understand what will happen. I think we can expect the worst,” Gattuso told Tierramérica*.

Trashing the Oceans: 3 to 6 X More Trash Than Plankton – ‘Using Oceans as Universal Sewer’ — Cousteau
This is a repost from last year. Sad to see little progress on this issue. — Stephen
“There is no reason for delay. Governments and industry need to take action and people have to stop pointing fingers at each other and get on with it.”
California nearly became the first U.S. state to ban plastic bags, but a multi-million-dollar lobby effort by industry killed the proposed legislation
By Stephen Leahy
HONOLULU, Hawaii, U.S., Mar 28, 2011 (IPS)
Every day, billions of plastic bags and bottles are discarded, and every day, millions of these become plastic pollution, fouling the oceans and endangering marine life.
No one wants this, but there is wide disagreement about how to stop it.
“Every time I stick my nose in the water, I am shocked. I see less and less fish and more and more garbage,” said Jean-Michel Cousteau, son of the legendary marine ecologist Jacques Cousteau, who has spent four decades making documentaries and educating people about the oceans.
Please throw something in the tip jar before reading on. This is how I make my living.
On trips to the remote and uninhabited northwestern Hawaiian Islands, Cousteau found miles and miles of plastic bottles, cigarette lighters, television tubes, spray cans, broken toys, and thousands of other pieces of plastic on the beaches and thousands of tonnes of derelict fishing nets in the reefs.
“We are using the oceans as a universal sewer,” he told some 440 participants from the plastics manufacturing, food and beverage sectors, environmental organisations, scientists and policy-makers from over 35 countries at the Fifth International Marine Debris Conference in Honolulu, Hawaii, which ended Mar. 25.

Selling Nature to Save Nature and Ourselves?
Humanity faces unprecedented challenge of climate change combined with food, water and energy shortages
“Markets are preconditioned on inequality and will only make matters worse”
By Stephen Leahy
THE HAGUE, Jul 5, 2011 (IPS)
Avoiding the coming catastrophic nexus of climate change, food, water and energy shortages, along with worsening poverty, requires a global technological overhaul involving investments of 1.9 trillion dollars each year for the next 40 years, said experts from the U.N. Department of Economic and Social Affairs (UN-DESA) in Geneva Tuesday.
“The need for a technological revolution is both a development and existential imperative for civilisation,” said Rob Vos, lead author of a new report, “The Great Green Technological Transformation”.
Absent in the U.N. report is a call for the other necessary transformation: what to do with the market-driven economic system that has put humanity on this catastrophic collision course? Attempts to “green” capitalism are failing and will fail, according to many of the more than 200 social science researchers at a groundbreaking international conference in The Hague titled “NATURE INC? QUESTIONING THE MARKET PANACEA IN ENVIRONMENTAL POLICY AND CONSERVATION“ Jun. 30 to Jul. 2.
“We must start tackling and questioning some core capitalist dictums, such as consumerism, hyper-competition, the notion that ‘private’ is always better, and especially economic growth,” says Bram Büscher, the conference co-organiser and researcher at the Institute of Social Studies (ISS) at Erasmus University in The Hague, Netherlands.
Equally important is to stop looking at nature as a collection of economic objects and services that “must only benefit some specific idea of human economic progress”, Büscher told IPS.
Governments, the World Bank, the United Nations and development agencies, international conservation organisations and others have all come to see markets as the only way to mobilise enough money to end deforestation, increase the use of alternative energy, boost food production, alleviate poverty, reduce pollution and solve a host of other serious and longstanding problems.
Started as a small gathering of academics, Nature Inc? became a major event as hundreds of experts from around the world wished to participate. Büscher believes the main reason for this is that many are actively doing research on environmental and conservation issues and are increasingly running into new market schemes like carbon credit trading, payments for ecosystem services, biodiversity derivatives and new conservation finance mechanisms, and so on.
“Payments for ecosystem services are the newest tropical ‘miracle’ crop,” said Kathleen McAfee of San Francisco State University.
The market is putting new values on tropical forests as carbon sinks, reservoirs of biodiversity or ecotourism destinations, McAfee said during the conference. Read the rest of this entry »
Brazil’s Forest Code and Land Speculators To Amp Up Amazon Deforestation Rates
90% of Forest in Apuí Converted into Pasture But the Real Profit is in Land Sales
By Stephen Leahy*
UXBRIDGE, Canada, Jul 28, 2011 (Tierramérica)
Many migrants from southern Brazil who clear forests in Brazil’s state of Amazonas are making their living as small-scale land speculators and not as farmers or as cattle ranchers, new research has found.
This on-the-ground reality and the proposed changes to Brazil’s Forest Code are likely to ramp up deforestation rates again, despite the country’s commitment to reduce deforestation 80 percent by 2020, experts say.
The Forest Code (Law 4771) was adopted in 1965 and has undergone numerous reforms, the most recent in 2001. This past May 24, an overwhelming majority in the Chamber of Deputies voted in favor of a bill to relax its requirements with regard to forest conservation. The bill is currently under study in the Senate. [Update Dec 28 2011]
A detailed study conducted in the municipality of Apuí along the Transamazon Highway in Amazonas found that many families in the region earned little income from cattle.
Instead, they were clearing the land in order to claim land titles to sell the land to large corporate ranchers, according to the study “Forest Clearing Dynamics and the Expansion of Landholdings in Apuí, a Deforestation Hotspot on Brazil’s Transamazon Highway”, published in the journal Ecology and Society in June.
From the early 1990s the population of Apuí has tripled, and the municipality has had some of the highest rates of deforestation in all of the state of Amazonas. Approximately 90 per cent of the area has been converted into pasture, the study found.
“These families are always moving into new forest areas to deforest so they can claim land title. And after a few years they sell it for a much higher price,” said study co-author Gabriel Carrero of the Institute for Conservation and Sustainable Development of Amazonas (IDESAM).

Plastic Circulating Endlessly in Oceans Killing Huge Numbers of Birds, Turtles, Fish and Marine Animals
“Degradable or compostable plastic should be banned….bio-plastics simply break down into microplastic particles”– scientist
By Stephen Leahy
HONOLULU, Hawaii, U.S., Mar 24, 2011 (IPS)
That plastic bottle or plastic take-away coffee lid that has 20 minutes of use can spend decades killing countless seabirds, marine animals and fish, experts reported here this week.
On remote Pacific island atolls, diligent albatross parents unknowingly fill their chicks’ bellies with bits of plastic that resemble food. The chicks die of malnutrition, and when their bodies decay all those plastic bottle tops, disposable lighters, and the ubiquitous bits of plastic detritus get back into the environment in a cruel perversion of ‘recycling’.
There is now so much plastic in the oceans it is likely that virtually every seabird has plastic in its belly if its feeding habits mean it mistakes plastic bits for food. The same is true for sea turtles, marine animals or fish, experts say.
Northern fulmars, a common seabird numbering in the millions, have a collective 45 tonnes worth of plastic bits in their bellies, estimates Jan Andries van Franeker, a biologist with the Institute for Marine Resources and Ecosystem Studies at the University of Wageningen in Holland.
At least 95 percent of fulmars in the North Sea where van Franeker has been working for three decades have one to several dozen bits of plastic in their stomachs. The same is true for related species like the tiny Wilson’s storm petrels, which unknowingly transport an estimated 35 tonnes of plastic from their wintering grounds in the North Atlantic to breeding grounds in the Antarctic, he says.
“If a seabird’s feeding habits mean it could mistake plastic for food, then it will likely have plastic in its stomach,” he said in an interview at the week long Fifth International Marine Debris Conference, which ends Friday in Honolulu, Hawaii. Read the rest of this entry »
Too many of us, taking too much and having too big an impact. Will need 27 planet Earths by 2050

“We were surprised the evidence from the past 30 years was so clear,” Mora told IPS.
The ability of protected areas to address the problem of biodiversity loss – the decline in diversity and numbers of all living species – has long been overestimated, the study reported. The reality is that most protected areas are not truly protected. Many are “paper parks”, protected in name only. Up to 70 percent of marine protected areas are paper parks, Mora said.
The study shows global expenditures on protected areas today are estimated at six billion dollars per year, and many areas are insufficiently funded for effective management. Effectively managing existing protected areas requires an estimated 24 billion dollars per year – four times the current expenditure.
“Ongoing biodiversity loss and its consequences for humanity’s welfare are of great concern and have prompted strong calls for expanding the use of protected areas as a remedy,” said co-author Peter Sale, a marine biologist and assistant director of the United Nations University’s Institute for Water, Environment and Health.
“Protected areas are a false hope in terms of preventing the loss of biodiversity,” Sale told IPS. Read the rest of this entry »
8.7 Million Species Run Spaceship Earth and Our Life Support System

We share the planet with 8.7 million species. We’re unconcerned about the ongoing loss of 200 species a day since we fail to realize they are our life support system. And we don’t know how many or which species are needed to keep things running. There is metaphor in the article to make that clearer I hope. We are not even close to coming to grips with this issue. – Stephen
“If the decline in species around us is not significant then I ask what is?”
By Stephen Leahy
UXBRIDGE, Canada, Aug 23, 2011 (IPS)
The life support system that generates the planet’s air, water, and food is powered by 8.7 million living species according to the newest and best estimate. We know next to nothing about 99 percent of those unique species – except that lots of them are going extinct.
“It is like a complicated engine where we only know about the major pieces. If we lose one or some of the small hidden pieces that play a critical role the engine might stop working,” said Camilo Mora of the University of Hawaii and Dalhousie University in Halifax, Canada.
“Many species may vanish before we even know of their existence, of their unique niche and function in ecosystems,” Mora told IPS.
Until now there wasn’t even a decent guesstimate about how many species exist currently: three million? 100 million? Now a new validated analytical technique has pined down the big number to 8.7 million species (give or take 1.3 million).
The analysis published Tuesday in the journal ‘PLoS Biology’ estimated there are 6.5 million species found on land and 2.2 million – about 25 percent of the total – dwelling in the ocean depths.

“Not knowing the answer to this fundamental question really highlights our ignorance about life on this planet,” said Boris Worm of Dalhousie University, co-author of the study along with Mora.
“We’re so fixated on the human enterprise we don’t recognise nature’s enterprise… the 8.7 million species that run the planet and provide the air we breathe, the water we drink and the soil we grow our crops in,” Worm told IPS. “If the decline in species around us is not significant then I ask what is? This is all we have on this planet, the only planet that holds life.” Read the rest of this entry »
