MADRID, May 29 2019 – No, no, no. Nothing to do with what US and Europe’s far-right fanatics now use to vociferate, saying once and again that “migrants come here to destroy our democracy, our civilisation, and our life-style”.

Rather the complete opposite—this is about a major damage that precisely “our civilisation” and “our lifestyle” have been causing: invasive alien species crossing the world chiefly on board of ships, and harming human health, biodiversity and the whole ecosystem.


Who are they?

“Invasive alien species are plants, animals, pathogens and other organisms that are non-native to an ecosystem, and which may cause economic or environmental harm or adversely affect human health…

For a species to become invasive, it must successfully out-compete native organisms for food and habitat, spread through its new environment, increase its population and harm ecosystems in its introduced range.

“In particular, they impact adversely upon biodiversity, including decline or elimination of native species -through competition, predation, or transmission of pathogens- and the disruption of local ecosystems and ecosystem functions…

“Invasive alien species, introduced and/or spread outside their natural habitats, have affected native biodiversity in almost every ecosystem type on earth and are one of the greatest threats to biodiversity. Since the 17th century, invasive alien species have contributed to nearly 40 percent of all animal extinctions for which the cause is known.” [2006 data]

This is how the Convention on Biological Diversity (CBD) defines the alien invasive species.

It warns that this problem continues to grow “at great socio-economic, health and ecological cost” around the world.

“Invasive alien species exacerbate poverty and threaten development through their impact on agriculture, forestry, fisheries and natural systems, which are an important basis of peoples’ livelihoods in developing countries. This damage is aggravated by climate change, pollution, habitat loss and human-induced disturbance.”

Where do they come from?

Globalisation has resulted in greater trade, transport, travel and tourism, all of which can facilitate the introduction and spread of species that are not native to an area, CBD experts the Convention on Biological Diversity explain.

For a species to become invasive, it must successfully out-compete native organisms for food and habitat, spread through its new environment, increase its population and harm ecosystems in its introduced range.

Most countries are grappling with complex and costly invasive species problems. For example, the annual environmental losses caused by introduced pests in the United States, United Kingdom, Australia, South Africa, India and Brazil have been calculated at over 100 billion dollars (CBD, 2006).

The Convention also warns that addressing the problem of invasive alien species is “urgent” because “the threat is growing daily, and the economic and environmental impacts are severe.”


Ballast water

In poor words, ships transporting merchandise from one extreme of the world to another, once they discharged their cargo, they once upon a time used to load heavy stones and rocks to ensure more stability to the vessels in their new maritime crossing. Later on, they started to load sea water instead of stones. This is the ballast water.

Then, upon their arrival to a new port, and before loading another cargo, they would discharge the water (ballast water) they loaded in another sea.

The point is that the water taken from one sea is full of living species and organisms which are natives of that specific ecosystem. The discharge of this ballast water obviously implies discharging those species and organisms to a different marine ecosystem.

Some of them would simply perish, but many more would survive at the cost of species and organisms, natives of the new habitat.


A major threat

“Ballast water is essential for the safe operation of ships. It provides stability and manoeuvrability during a voyage and during loading and unloading operations,” explains the European Maritime Safety Agency (EMSA). Management of ballast water also reduces the hull stress caused by adverse sea conditions or by changes in cargo weight as well as fuel and water.

However, EMSA also explains that the process of loading and unloading untreated ballast water poses a major threat to the environment, public health and the economy as ships become a vector for the transfer of organisms between ecosystems, from one part of the world to another.

“When ballast water is taken up in port, many microscopic organisms and sediments are introduced into the ships ballast tanks. Many of these organisms are able to survive in these tanks, and, when ballast water is discharged, they are released into new environments.”

If suitable conditions exist in this release environment, these species will survive and reproduce and become invasive species.

“In some cases, there is a high probability that the organism will become a dominant species, potentially resulting in: the extinction of native species, effects on local/regional biodiversity, effects on coastal industries that use water extraction, effects on public health and impacts on local economies based on fisheries.”

Extensive damage

The European Maritime Safety Agency further warns that “ballast water discharge typically contains a variety of biological materials, including plantsanimalsviruses, and bacteria. These materials often include non-native, nuisance, exotic species that can cause extensive ecological and economic damage to aquatic ecosystems, along with serious human health issues including death.”

For its part, the International Maritime Organization (IMO) explains that ballast water is routinely taken on by ships for stability and structural integrity. It can contain thousands of aquatic microbes, algae and animals, which are then carried across the world’s oceans and released into ecosystems where they are not native.

“Untreated ballast water released at a ship’s destination could potentially introduce new invasive aquatic species. Expanded ship trade and traffic volume over the last few decades have increased the likelihood of invasive species being released. Hundreds of invasions have already taken place, sometimes “with devastating consequences for the local ecosystem, economy and infrastructure.”



The dominating ‘life-style’, generated by the “Take-Make-Dispose” economic model, which is based on over-production/over-consumption/over-commercial benefits, has massively increased international transporting systems.

From big trucks using fossil fuel, to giant cargo ships over-loaded with enormous containers –let alone huge oil tankers, the fact now is that around 80 percent of global trade by volume and over 70 per cent of global trade by value are carried by sea and are handled by ports worldwide. Updated estimates situate these figures in 90 per cent and 80 per cent, respectively.

The United Nations Conference on Trade and Development (UNCTAD) in 2016 estimated that there are more than 50,000 merchant ships trading internationally, transporting every kind of cargo. The world fleet is registered in over 150 nations and manned by more than a million seafarers of virtually every nationality.

For its part, the Food and Agriculture Organisation of the United Nations (FAO) also in 2016 estimated that some 1.1 trillion dollars-worth of agricultural products are traded internationally each year.

This “Take-Make-Dispose” economic model has proved to be one of the world’s main killers due to the huge pollution it causes for air, land and soil, marine and freshwater.

Moreover, this prevailing economic model implies that over one third of food is lost and/or wasted, enough to feed all hungry people.



Invasive alien species arrive in new habitats through various channels, being shipping the main one. Though important, they are not the sole problem the voracious production-consumption model brings.

For instance: containers. According to the Floating Threat report, “shipping today means sea containers: Globally, around 527 million sea container trips are made each year – China alone deals with over 133 million sea containers annually.”

“It is not only their cargo, but the steel contraptions themselves, that can serve as vectors for the spread of exotic species capable of wreaking ecological and agricultural havoc.”


There are increasing warnings of an imminent new financial crisis, not only from the billionaire investor George Soros, but also from eminent economists associated with the Bank of International Settlements, the bank of central banks.

More floating threats

In addition to the invasive alien species, the fact that over 80 per cent of global trade is carried by sea also implies other invisible treats –while ships bring coffee, snacks and TV sets, they also carry pests and diseases.

In its ‘A Floating Threat: Sea Containers Spread Pests and Diseases’, FAO highlights that while oil spills garner much public attention and anguish, the so-called “biological spills” represent a greater long-term threat and do not have the same high public profile.

“It was an exotic fungus that wiped out billions of American chestnut trees in the early 20th century, dramatically altering the landscape and ecosystem, while today the emerald ash borer – another pest that hitch-hiked along global trade routes to new habitats – threatens to do the same with a valuable tree long used by humans to make tool handles, guitars and office furniture.”

The specialised world body also reminds that perhaps the biggest “biological spill” of all was when a fungus-like eukaryotic microorganism called Phytophthora infestans – the name of the genus comes from Greek for “plant destroyer” – sailed from the Americas to Belgium. Within months it arrived in Ireland, triggering a potato blight that led to famine, death and mass migration.

“The list goes on and on. A relative of the toxic cane toad that has run rampant in Australia recently disembarked from a container carrying freight to Madagascar, a biodiversity hotspot, and the ability of females to lay up to 40,000 eggs a year make it a catastrophic threat for local lemurs and birds, while also threatening the habitat of a host of animals and plants.”

The report A Floating Threat: Sea Containers Spread Pests and Diseases’ estimates that up to 90 percent of world trade is carried by sea today, with vast panoply of differing logistics, making agreement on an inspection method elusive.

“Moreover, many cargoes quickly move inland to enter just-in-time supply chains. That’s how the dreaded brown marmorated stink bug – which chews quickly through high-value fruit and crops – began its European tour a few years ago in Zurich.”

This animal actively prefers steel nooks and crannies for long-distance travel, and once established likes to set up winter hibernation niches inside people’s houses.

The list of dangers the current economic model –and “our civilisation” and “our life-style” pose day after day is too long to be summarised in just one report. The uncontrolled threats of the invasive alien species are just an example.

Any hope that humans wake up… perhaps by attentively listening to Greta Thunberg –and with her the already mobilised world’s youth:

“You say you love your children above all else, and yet you are stealing their future in front of their very eyes… We cannot solve a crisis without treating it as a crisis…if solutions within the system are so impossible to find, then… we should change the system itself.”

US “Emergency” Arms Sales to Mideast Nations Under Fire

UNITED NATIONS, May 29 2019 – When the UN Security Council met last week to discuss the deaths and devastation caused to civilians in ongoing military conflicts and civil wars, the killings in Yemen and the air attacks on hospitals, schools, mosques, and market places—whether deliberate or otherwise– were singled out as the worst ever.

But the destruction and irreparable damage to civilian infrastructure and human lives were caused by weapons provided by some of the permanent members of the Security Council, including the US, France and UK.

And last week, in defiance of US Congressional opposition to arms sales to some of the warring Middle Eastern nations, the Trump administration went one better: it justified the proposed sale of a hefty $8.1 billion dollars in American arms to Jordan, the United Arab Emirates (UAE) and Saudi Arabia under a so-called “emergency notification”.

All three countries are part of a Saudi-led coalition unleashing attacks on Yemen battling Houthi insurgents backed by Iran– and the new weapons systems are expected to add more fire power to the coalition.

The “emergency notification” for arms sales was not only an act of defiance against the US Congress but also an attempt to placate American allies in the Middle East and, more importantly, the powerful arms lobby in the United States.

One of arguments adduced by the Trump administration is that increasing arms sales to Middle Eastern allies are meant to counter an “anticipated Iranian aggression”.

Stephen Zunes, Professor of Politics at the University of San Francisco and coordinator of the program in Middle Eastern Studies, told IPS this is not about deterring Iranian aggression and it is certainly not an “emergency.”

“It’s about the profits of American arms manufacturers at the expense of countless Yemeni lives.”

“This is but the most extreme manifestation, however, of a longstanding bipartisan policy of transferring deadly and sophisticated armaments to the family dictatorships in the Middle East”, said Zunes, who also serves as a senior policy analyst for Foreign Policy in Focus project of the Institute for Policy Studies.

He pointed out that It is ironic that a nation which emerged in revolution against monarchy, would be the world’s number one arms supplier of absolute monarchies today.

According to a story in the Wall Street Journal May 25, the Houthis are less ideologically aligned with Tehran, and Iran denies arming the group. But US officials disagree, saying Iran has trained them and provided them with weapons.

UN Secretary-General Antonio Guterres told the Security Council May 23 that civilians continue to make up the vast majority of casualties in conflict, with more than 22,800 civilians dying or being injured in 2018 in just six countries: Afghanistan, Iraq, Mali, Somalia, South Sudan and Yemen.

He stressed the need for the Security Council to do more to enhance compliance with the laws of war.

In a statement released last week, the London-based Amnesty International was dead on target when it ridiculed the US argument that some of the weapons supplied to the Saudi-led coalition were “precision-guided” to avoid civilian casualties.

“The great military powers cynically boast about ‘precision’ warfare and ‘surgical’ strikes that distinguish between fighters and civilians. But the reality on the ground is that civilians are routinely targeted where they live, work, study, worship and seek medical care.”, the statement added.

AI said parties to armed conflict unlawfully kill, maim and forcibly displace millions of civilians while world leaders shirk their responsibility and turn their backs on war crimes and immense suffering.

Asked for his comments, Philippe Nassif, Advocacy Director – Middle East and North Africa at Amnesty International, told IPS decision made by President Trump to circumvent Congress and authorize billions of dollars’ worth of arms sales to serial human rights abusers Saudi Arabia and the UAE is extremely unfortunate and reckless.

“Both these countries have used US made weapons to commit war crimes in Yemen, a country mired in conflict that has been made worse by the conduct of the UAE and Saudi led coalition,” he added.

The Trump administration has had a blank check policy when it comes to arming its Middle Eastern allies, from Egypt to Saudi Arabia.

Nassif pointed out that the atrocious human rights records of these governments, where executions, extrajudicial killings, mass incarceration, torture, and indefinite detentions are part of daily life for their citizens, is made worse by the US continuing to arm these governments.

“Now that the UAE and Saudi Arabia will receive new American weapons, we can expect a continuation of the hell that has been brought upon Yemen, where 11 million people are suffering from famine, hundreds of thousands have been displaced, and thousands killed,” he noted.

“We can also expect weapons to fall into the wrong hands, such as Al Qaeda, or be sent to other conflict zones where the Saudi’s and UAE are backing ascending autocrats, such as Haftar in Libya,” Nassif declared.

In a statement released May 24, US Secretary of State Mike Pompeo said “I made a determination pursuant to section 36 of the Arms Export Control Act and directed the Department to complete immediately the formal notification of 22 pending arms transfers to Jordan, the United Arab Emirates, and Saudi Arabia totaling approximately $8.1 billion to deter Iranian aggression and build partner self-defense capacity”.

“These sales will support our allies, enhance Middle East stability, and help these nations to deter and defend themselves from the Islamic Republic of Iran,” he said.

Delaying this shipment, Pompeo argued, could cause degraded systems and a lack of necessary parts and maintenance that could create severe airworthiness and interoperability concerns for key partners, during a time of increasing regional volatility.

He argued that national security concerns have been exacerbated by many months of Congressional delay in addressing these critical requirements, “and have called into doubt our reliability as a provider of defense capabilities, opening opportunities for U.S. adversaries to exploit.”

The equipment to the three countries includes aircraft support maintenance; intelligence, surveillance, and reconnaissance (ISR); munitions; and other supplies.

“Today’s action will quickly augment our partners’ capacity to provide for their own self-defense and reinforce recent changes to U.S. posture in the region to deter Iran. I intend for this determination to be a one-time event,” Pompeo added.

He pointed out that Section 36 is a long-recognized authority and has been utilized by at least four previous administrations since 1979, including Presidents Reagan and Carter.

“This specific measure does not alter our long-standing arms transfer review process with Congress. I look forward to continuing to work with Congress to develop prudent measures to advance and protect U.S. national security interests in the region,” he declared.

The United States is, and must remain, a reliable security partner to our allies and partners around the world. These partnerships are a cornerstone of our National Security Strategy, which this decision reaffirms, Pompeo said.
