"For twenty-five centuries, Western knowledge has tried to look upon the world. It has failed to understand that the world is not for the beholding. It is for hearing. It is not legible, but audible."

Organisations should "develop a semiotic ability to read waste in its social and natural contexts, and to develop a corresponding sense of responsibility for the materials that the organizations consume and invite to consume."
"Challenging that organizations are carelessly given a nearly unconditional right to waste in the name of economic production, a scatolic understanding of waste makes clear that organizational wasting practices are everybody’s affair, inclusive of animals, seas, the Earth, and coming generations."
Waste is "any substance or object which the holder discards or intends or is required to discard."

"We define resourcification as the social processes involved in turning something into a resource. This definition shifts the focus away from essentialist queries about the amount or features of resources to the study of their becoming resources. Correspondingly, we define deresourcification as the processes through which something is no longer considered a resource."
"Our goal is the creation of a critical, interdisciplinary platform to identify, describe, and explain interactions among humans, other living organisms, and the environment."
"It follows, therefore, that although the use of resources is a condition for all life, our agenda is concerned with anthropogenic resourcification under the increasingly perilous conditions of the Anthropocene."
"Anthropogenic resourcification is founded on extractivism: the exploitation of soil nutrients, minerals, and other extractable things. Extractivism is based on the anthropocentric assumption that natural and human-made environments, materials, processes, and beings – including humans – are a cheap and ready-to-resourcify stock of inputs waiting to be dominated and exploited. Extractivism applies to what is seen as both renewable and non-renewable resources."
"Internet technology made it possible for intermediaries such as Amazon, Airbnb, and Alibaba to develop global market-making infrastructures that resourcify themselves and the suppliers and customers they connect"
"Resourcification is conditioned upon the practical possibility of abstracting and extracting the potential resource from its current setting and moving it to a new geographical, social, and technological setting."

Name

Native to

Introduced to

Impact

Asian paddle crab

Charybdis japonica

North-west Pacific (China, Japan, Korean peninsula) to east Asian Seas (Thailand, Malaysia)

New Zealand

May carry the White Spot Syndrome virus which can affect crustacean mariculture. Can affect biodiversity through either predation or by indirectly altering trophic levels.

Colonial tunicate

Didemnum vexillum

North-west Pacific

North-east and north-west Atlantic, north-east Pacific, New Zealand

This species is an aggressive invader and is able to reproduce sexually or asexually. Fragments of the species are able to disperse, reproduce, reattach and thrive. This species fouls hydrotechnical constructions, ships, aquaculture infrastructure and cultured molluscs. It affects the biodiversity of existing communities as it outcompetes for habitat or simply grows over or smothers existing species.

North Pacific seastar

Asterias amurensis

North-west Pacific

North-east Pacific, southern Australia

This species is a voracious carnivorous feeder. They are prolific breeders and are able to quickly establish large populations in new areas. The species is a serious pest to native species, such as the endangered spotted handfish (Brachionichthys hirsutus), as the seastar preys on the fish’s egg masses. The species’ preference for mussels, scallops and clams ensures that it impacts mollusc aquaculture and wild fisheries.

Asian green mussel

Perna viridis

Persian Gulf through to the Philippines, east Asian seas and up to eastern China

Caribbean, south Atlantic, south Pacific

Tolerates wide fluctuations of salinity and temperature and reaches high densities. This species fouls hydrotechnical constructions, ships and aquaculture infrastructure. It affects the biodiversity of existing communities and can alter trophic levels.

Black striped mussel

Mytilopsis sallei

North-west Atlantic, Caribbean and south Atlantic

India, east Asian seas (Malaysia, Singapore), south Pacific, north-west Pacific (Japan, China)

Tolerates wide fluctuations of salinity and temperature. Highly fecund, grows and reaches maturity rapidly. This species is capable of forming dense aggregations, impacting biodiversity as they exclude most other species. The fouling of hydrotechnical constructions, ships and aquaculture infrastructure with this species causes corrosion, technical problems and loss of efficiency.

European fan worm

Sabella spallanzanii

North-east Atlantic, Mediterranean

South-west Atlantic, southern Australia, New Zealand, north-west Pacific

This species is highly fecund and is able to form mat-like, dense populations on the seafloor. The species can tolerate wide ranges in salinity and successfully fouls artificial structures such as hydrotechnical constructions, ships and aquaculture infrastructure. The species competes with native filter-feeding organisms for habitat and food. It is possible that dense formations alter water flow, sediment stability and bacterial communities due to their efficiency filtering particulate matter from the water column.

Bay barnacle

Amphibalanus improvisus

Thought to be the east coast of north-east and north-west Atlantic

South-west Atlantic, Caribbean Sea, Atlantic, Baltic Sea, Black Sea, Caspian Sea, north-west Pacific, east Asia seas

This species is fast growing and gregarious. It has high reproductive potential; being able to reproduce sexually and asexually. Tolerates wide fluctuations of salinity and temperature. The fouling of hydrotechnical constructions, ships and aquaculture infrastructure with this species causes corrosion, technical problems and loss of efficiency. Able to affect biodiversity, change community structures and alter trophic levels.

Wakame seaweed

Undaria pinnatifida

North-west Pacific

Mediterranean, north-east Atlantic, south-west Atlantic, north-east Pacific, south-east Australia, New Zealand

This species is able to rapidly colonise temperate regions; it can colonise any hard surface and is therefore able to foul hydrotechnical constructions, ships and aquaculture infrastructure. Able to affect biodiversity, change community structures and alter trophic levels.

European shore crab 

Carcinus maenas

North-east Atlantic, Baltic Sea

West Africa (Mauritania to South Africa), Mediterranean, north-west Atlantic, south-west Atlantic (Panama to Argentina), east Africa (Red Sea to South Africa, including Madagascar), Japan, north-east Pacific, Myanmar, Sri Lanka, south Pacific, south-eastern Australia

The adult specimens of this species are able to withstand wide ranging temperature and salinity fluctuations. It is able to reside in damp air exposed environments for up to 10 days and tolerate up to 3 months of starvation. However, when able to feed, this species is a voracious predator, preying on molluscs and other crustaceans, including commercially important species. Apart from impacting on native species through predation, this species disrupts existing community structures through competition (habitat and food) and behavioural activities (burrowing).

"Foetal ultrasonic scanning is now so established in industrialised nations that it would now be difficult to find a control group for epidemiological studies."
"The limiting feature for the use of ultrasound in air is the severe absorption which rapidly reduces the amplitude of the field, as it propagates away from the source, to levels which are too low for most processing activities, or even to provide sufficient signal-to-noise ratios (SNRs) for many diagnostic applications. There is however one exception, the manifestation of which illustrates a key point which must be appreciated in the assessment of the safety of ultrasound in air.
"The human ear is an extremely sensitive sensor for acoustic waves. Intensities which are low by the standards used for ultrasonic diagnostic technology, and certainly for ultrasonic processing, are generally very much higher than the maximum intensities which the human ear can sustain at audio frequencies without damage. Therefore when ultrasound is used to generate signals to which the ear can responds [sic] (which may not necessarily be restricted to audio frequencies—see Section 6), whilst the resulting intensities may be thought of as ‘low’ from the perspective of many ultrasonic technologies, they may be ‘high’ from the perspective of the ear. This point is discussed further in Section 7."
"Given the paucity of information on the safe levels for human exposure to ultrasound in air (Section 6), and the lack of traceability for the measurement of such fields (see Section 2.3), this could be a safety issue."
Leighton suggests three categories of exposure to ultrasound production, the first of which he classifies as ultrasonic noise exposure:
  1. ultrasound generated by some device as a byproduct of its operation (unintended exposure)
  2. ultrasound generated explicitly by some device and fundamental to its operation (unintended exposure e.g., ultrasonic rangefinder, automatic door openers)
  3. ultrasound generated in order to have an effect on humans and/or to change their behaviour (intended exposure).

"recent data suggest 1 in 20 people aged 40–49 years have hearing thresholds that are at least 20 dB more sensitive at 20 kHz than that of the average 30–39 year old. Moreover, 5% of the 5–19 year age group is reported to have a 20 kHz threshold that is 60 dB more sensitive than the median for the 30–39 year age group"
"For over 40 years, there have been reports of hearing threshold shift . . . and a range of subjective effects (nausea, dizziness, migraine, fatigue, tinnitus and ‘pressure in the ears’ . . .) from ultrasound in air to which workers have been routinely exposed (plus other symptoms that have not occurred in more than one study . . .). The degree of response, from significant to none, varied between workers. The evidence base has not studied sufficient numbers of subjects, and has not been sufficiently sensitive to the presence of sensitive individuals, or sensitive subgroups, within the population, to support the guidelines required today. Studies focused on occupational exposure to ultrasound, which tends also to occur alongside high levels of audible sound, and the effect of this audio frequency noise on the observed effects must be isolated because there is increasing public exposure to ultrasound without such audible cues. Measurement methods and audiological procedures in the past have tended to follow extrapolations of methods used in the audio frequency range which, alongside the calibrations and allowed tolerances of the equipment used, must be critically examined . . . . It is therefore no simple matter to measure the very high frequency/ultrasonic (VHF/US) fields to which people are exposed, either in situ or during audiological testing, and relate those to the levels quoted in past studies. Consequently, the evidence to date has been wholly inadequate to inform the development of guidelines for the increasing exposure of the public to ultrasound in air, and is suspect for occupational exposure."

"ultrasonic energy at frequencies above about 17kHz and at levels in excess of about 70dB may produce adverse subjective effects experienced as fullness in the ear, fatigue, headache, and malaise."
Different recommendations and regulations around the globe for exposure to ultrasound: WHO 110dB, USA and Seden, 115dB, and Norway 120dB for frequencies higher than 22kHz (3rd 8ve band).

"According to information I have received concerning the sound perception of night moths, it makes no difference whether the sound to which the animals are adjusted be the sound manifestation of a bat or one produced by rubbing a glass stopper — the effect is always the same. Night moths which, owing to their light coloring, are easily visible, fly away upon perceiving a high tone, while species which have protective coloration alight in response to the same tone. The same sensory cue has the opposite effect in their case. It is striking how the two opposite kinds of action are governed by a plan. There can be no question of discrimination or purposiveness, since no moth or butterfly has ever seen the color of its own skin. The plan revealed in this instance appears even more admirable when we learn that the artful microscopic structure of the night moth's hearing organ exists solely for this one high tone of the bat. To all else, these moths are totally deaf."

"Modern advances in science and technology change man's environment, introducing new factors which, besides their intended beneficial uses, may also have untoward side-effects [...] The more frequent use of ultrasound in industry, commerce, the home, and particularly in medicine, has magnified the possibility of human exposure, increasing concern about possible human health effects, especially in relation to the human fetus."
