Commemorative Days for the 20th anniversary of the Les Saintes earthquake
Twenty years after the Saintes earthquake of November 21, 2024, which left one dead, 13 injured, 40 homeless, and above all a large number of disorders on the islands of Saintes, Basse-Terre, and Marie-Galante, looking back on this major event of the last 100 years is important, especially since these disorders are still visible and still impact essential tourist sites for Guadeloupe, such as access to the Soufrière or the second Carbet waterfall.
Two commemorative days are therefore organized in Terre-de-Haut on Friday 22 and Saturday 23 at the Place des Héros in Terre-de-Haut. These days aim to:
- reassess the seismic hazard;
- discuss the assessment of buildings;
- take stock of crisis management;
- and provide feedback on both the events of Les Saintes in 2004 and Haiti in 2010.

Tribute to Bernard Pottier
Bernard in Vietnam 2016
These few words will certainly not ease your pain, just as they did nothing to soften my own. But I hope they will help ensure that the memory of this great man endures through the kindness of his actions and the depth of his love.
Meeting Bernard Pottier was a gift for me—a chance to come close to a scientist who, despite all the constraints of the system he had to navigate, managed to keep his convictions, his faith in humanity, and his commitment to clarity and fairness in his explanations. Bernard restored my hope in the academic ecosystem and the beauty of knowledge. Like a true mentor, from our very first meetings, he described to me, in just the right words, the field of possibilities for a geophysicist like myself in the information sciences.
Speaking with Bernard felt like returning to the source, to the very foundation of thought. Never a word out of place, always striving to dispel the darkness of this world. Asking a question of Bernard was like asking a question of a wise cat, who, after a thoughtful twitch of his whiskers, would pounce on the answer with boundless generosity.

Political choices on water in Guadeloupe – the question of Morality
For ethics and moralization of public services, a necessary shift
Memorandum written for the conference series on water in Guadeloupe organized by the Men's Group of the Saint-André Parish of Morne-à-l'Eau between May and June 2024
WATER, a vital resource, so familiar
We are far from the time of the 1980s and 1990s when the lack of water was only due to social demands and strike movements. The expansion of the drinking water network and the increase in needs with, among other things, the irrigation network seems to have placed Guadeloupe in a water shortage. This is not the case since annual water needs are largely covered by tropical rainfall. There are significant contributions of meteoric water to the mountain ranges of Basse-Terre between 3500 and 8000 mm of rainfall per year, underground reserves in Grande-Terre and Marie-Galante maintained by rainfall between 1500 and 1800 mm per year. This poor geographical distribution of water resources requires the movement of large bodies of water to compensate for the daily needs of the archipelago, particularly around the large urban centres of Pointe-à-Pitre, Les Abymes and Baie-Mahault or the areas with high tourist activity such as Saint-François, Sainte-Anne and Deshaies. The water problem in Guadeloupe comes from the 63% of water lost in nature due to a poorly designed and poorly maintained water network.
Drinking water
Drinking water is intended for food and hygiene. This type of water use requires the most physicochemical and biological control analyses. Analyzes include, among others: colour, turbidity, odour, and flavours; the temperature, the acidity of the water; the levels of chlorides, sulfates, and nitrates; the presence of toxic substances such as arsenic, cadmium, lead and hydrocarbons; microbiological analysis of faecal germs such as intestinal enterococci and Escherichia coli. Analyzes are constant and carried out by organizations such as the Regional Health Agency regularly depending on quality problems. Water purification treatments are centralized within factories of varying sizes.
The regulations and design of drinking water distribution in force provide for water treatment before any distribution over more or less long distances and buffer storage via water towers to guarantee supply, pressure water and absorb flow variations on the network. But this method requires being able to provide water continuously. A disruption in the supply or prolonged storage of water causes it to lose its potability by, for example, reducing the chlorine level.
The distribution of drinking water must therefore be carried out continuously. But water sources in Guadeloupe are not uniformly distributed across the territory. Most of the rivers and catchment points are in Basse-Terre. Most of the natural storage in Guadeloupe (groundwater) is on the islands of Grande-Terre and Marie-Galante. The use of groundwater is currently limited by recharge and the risks of saltwater intrusion and pollutants. The location of exploitable water sources being non-homogeneous and especially available on Basse-Terre requires significant quantities of water to be transported continuously via a complex and generally difficult-to-transport water supply network, particularly for a developing territory.
The transport of water through a network made up of pipes, valves, elbows and temporary storage areas requires maintaining high pressure to guarantee flow rates and mitigate friction caused by the natural viscosity of the water. Friction contributes to the deterioration of water pipes in the same way as external constraints such as burial, ground movements or plant growth. High pressures promote leaks and weakening of pipe walls. The high-pressure mode of transport leads to additional costs for equipment maintenance.
Wastewater treatment – water regeneration
After use, the water is said to be grey or black; it has dissolved organic or mineral elements and is loaded with waste and chemical compounds. Waste water is unfit for consumption and must be purified, filtered, decontaminated and disinfected. Water sanitation relies on the physical characteristics of water such as molecule size, density, polarity and surface tension. These characteristics can be used to get rid of the organic matter, minerals and biomass it carries. Sanitation can be carried out by combining decantation, filtering (microfiltration, ultrafiltration, nanofiltration and reverse osmosis), oxygenation and fermentation (methanization).
Water discharged in urban, rural or coastal areas with high concentrations of pollutants and waste (diluted molecules, particles, organic matter, microorganisms) is difficult to manage by nature. Waste accumulates and suffocates water and soil due to low-speed processing or excessive volumes. The accumulation of particles, organic matter and pollutants on the wastewater route (urban or rural water cycle) will cause localized pollution and modification of ecosystems. Areas of pollution can last for years, even centuries, and cause increases in pollution years later. Particularly in very compact and poorly oxygenated soils which will filter polluted water. The degradation of pollution and toxic molecules in anoxic conditions is generally very slow.
The regeneration of wastewater requires the setting up of sanitation structures adapted in number and treatment capacity, particularly during periods of heavy rain. It can also pass the rejection of smaller quantities adapted to the plant and microbial ecosystem. The use of certain substances makes natural regeneration more difficult or even impossible; we can talk about antibiotics, persistent organic pollutants and other toxic substances which destroy the ecosystems that must participate in regeneration.
Water sanitation-regeneration must not only be seen on the scale of increasingly expensive treatment equipment but also at the scale of the ecosystem where they are installed and consumption patterns and lifestyle habits. The current choices are all based on a European vision and rich and temperate countries, it would be useful to reinvent its systems to adapt them to our environmental reality even if it means prohibiting or modifying the use of certain molecules to facilitate the treatment of wastewater.
Behaviours, commitments and objectives to modify to find a balance
There are a certain number of questions that we are entitled to ask ourselves for the future of the distribution of drinking water and the sanitation of wastewater in Guadeloupe. Particularly in a difficult economic period and with a delay in investment which forces us to work on updating the networks urgently both to allow everyone to have access to drinking water of quality in quantity and to preserve the coastal environment by no longer discharging water that is dangerous for ecosystems.
Questions ?
Should water distribution be continuous in Guadeloupe? Should water storage and treatment be systematically centralized with current technological advances? Doesn’t the availability of water in spread networks require us to have a greater number of storage areas? Shouldn’t water storage be at the scale of neighbourhoods or houses? Shouldn’t sanitation be based more on solutions from nature-inspired? To facilitate sanitation and the preservation of nature, shouldn’t we still regulate the use of certain molecules?
The evaluation of the cost of compliance and rehabilitation of the water and sanitation networks is estimated at 2 billion euros, one billion for each of these two networks. This sum, even if it may seem overestimated, clearly indicates the challenge that Guadeloupe will have to face. In any case, this amount of money will be difficult to mobilize, whether there is a French national solidarity or not. Conducting projects on financial volumes of this level will not fail to generate greed and corruption. A first level of morality should be assumed by Guadeloupeans and public service employees in order not to be disturbed by the power of money and the advantages that certain choices could generate rather than others.
Current models of water and sanitation networks are based on solutions from developed countries, most often in temperate climates. Solutions more suited to the financial, technical and environmental capacities of Guadeloupe must be offered at appropriate costs, above all by existing agents, assisted or not by external structures. These agents must become aware of the importance of their involvement in building and implementing appropriate solutions. They must be morally ready to refuse simplistic solutions and dogmas imposed by manufacturers while being proactive in proposing regulatory changes. They must also be ready to give way to others if certain subjects or problems are outside their competencies.

Happy New Year 2024
A year that begins, a new tour that begins around our main source of energy and life: the Sun.
Yesterday’s problems have not disappeared, new ones will appear and in our increasingly demanding environment, we must respond collectively and truthfully to the challenge of evolution.
2024 let us open our horizons: our minds, our hearts, our eyes to knowledge and others.
TCGNRG wishes you a happy new year and assures you its support for all these challenges
Plenary meeting to launch the Guadeloupe Regional COP
We were there
The context
On Tuesday, November 14, 2023, at 2:15 p.m., the plenary meeting to launch the Regional COP (Regional Conference of the Parties) was held at the Raizet regional space. TCGNRG was there and gives you its reading of the exchanges and this new system for ecological planning
According to the Ministry of Ecology website, the Regional COP aims to « […] à décliner région par région, à l’échelle de l’action concrète, ces objectifs nationaux de réduction des émissions de gaz à effet de serre, de biodiversité, de préservation des ressources ,e d’économie circulaire et d’adaptation. »1 (“[…] to decline region by region, on the scale of concrete action, these national objectives for reducing greenhouse gas emissions, biodiversity, resource preservation, circular economy and adaptation.”)
The parties concerned are « […] les collectivités d’une part, mais aussi les entreprises, les associations et les fédérations professionnelles. »1 (“[…] communities on the one hand, but also companies, associations and professional federations.”)
The provisional calendar for the Regional COPs provides: « […] Cet hiver (décembre en Guadeloupe) : établissement d’un diagnostic partagé et co-construit avec les collectivités territoriales; Au printemps 2024 (mars-avril en Guadeloupe) : co-construction avec tous les acteurs des leviers d’action; À l’été 2024 (juin-juillet en Guadeloupe) : pour chaque COP, finalisation des feuilles de route pour l’horizon 2030, au sein du territoire. »1 (“[…] This winter (December in Guadeloupe): establishment of a shared and co-constructed diagnosis with local authorities; In spring 2024 (March-April in Guadeloupe): co-construction of action levers with all stakeholders; In the summer of 2024 (June-July in Guadeloupe): for each COP, finalization of roadmaps for 2030, within the territory.”)
The joint invitation from the prefecture and the Guadeloupe Region of November 10, 2023
calls for « […] (aujourd’hui) de construire une stratégie avec les acteurs de terrain pour élaborer un projet de territoire qui contribue aux objectifs nationaux de transition écologique » (“[…] (today) to build a strategy with field stakeholders to develop a territorial project that contributes to the national objectives of ecological transition”) through the meeting to launch ecological planning in the territory.
By organizing the launch plenary, on November 14th, Guadeloupe is the second French region to launch its COP after the Grand Est region and the first outermost region. Guadeloupe therefore wants to be at the head of the regions for ecological planning even though public transport is poorly developed, recycling is almost non-existent and aquatic environments are dramatic both chemically and ecologically. We must hope that the energy put into embracing this new body will make it possible to bring about real change and not anachronistic decision-making by a developing region applying the references of the former 6th world power.
Progress of the launch plenary
After the introductory remarks from the Prefecture, the Regional Council, the Departmental Council, the association of Mayors and the Minister in charge of Ecological Transition and Territorial Cohesion and in charge of the Territorialization of ecological planning (recorded video), three presentations were made to introduce the climatic and ecological context of Guadeloupe:
A first presentation was by a lecturer from the University of the Antilles on the climate of Guadeloupe. Unfortunately, the presentation was more focused on the work carried out by his research group than on the state of knowledge of the climate of Guadeloupe. This is undoubtedly linked to the underfunding for research, particularly on climate change, granted to the University of Antilles.
The second presentation was that of the Environment and Energy Management Agency (ADEME) Guadeloupe on the issues of climate change and the reduction of greenhouse gases. Unfortunately, this presentation was based on a political definition of the uses of biofuels and not a physical or climatic one. The switch to biofuels at the Jarry thermal power station will make it possible to consider, thanks to the political definition of renewable energies, that Guadeloupe’s electricity network will be 100% based on renewable energies by 2024-2026. In fact, this thermal power station and that of Le Moule (bagasse/wood/coal) rely on fossil and non-renewable energies. These two power plants therefore have nothing physically (i.e. climatically) green. ADEME Guadeloupe considers that the main challenge will be transport, which is true, but the matter of the electrical network and electricity production is not proportionally resolved. Questions and comments from the public on the Multi-year Energy Program (PPE) and the place given to Geothermal Energy showed the non-acceptance of the energy trajectory proposed by the Guadeloupe Region. The question of energy does not generate consensus among the population and is still far from being climatically virtuous.
The third presentation on the state of biodiversity in Guadeloupe was made by the president of the board of directors of the French Biodiversity Office (OFB). The latter is slow to establish itself as a scientific reference on biodiversity in Guadeloupe, despite its academic qualifications. Numerous questions and comments have, also for this subject, shown the population’s non-acceptance of the current management of the territory and in particular of its biodiversity.
The numerous tensions during this introduction sequence suggest that the conditions are not met for peaceful exchanges on the two issues of climate and biodiversity, both on the side of civil society which denounces a refusal of democracy and of the elected representatives of the regional majority who have difficulty accepting comments and reproaches. The recent update of the PPE and the Regional Plan for Economic Development, Innovation and Internationalization (SRDEII) showed this, leaving a strong feeling in civil society which had mobilized.
The proposals made by DEAL Guadeloupe provide that the Regional COP will work with six thematic groups which will have to work on the six themes of France Nation Verte (France Green Nation), that is to say: better housing, better travel, better protection of our ecosystems, better produce, eat better, consume better. A final group will be responsible for the synthesis. The regional COP will have to propose regional planning to meet national commitments. A list of action levers must therefore be proposed, 52 of which have already been identified by France Nation Verte (see elements of this list at the end of the document), to resolve the five environmental challenges of mitigation, adaptation, biodiversity, resource management and health by 2030.
The main question that can be asked is whether this approach has a chance of proposing a direction consistent with the physical realities of the Guadeloupe archipelago and allowing it to develop while taking its share of responsibility for the reduction of greenhouse gases and protection of (global) biodiversity.
Our analysis of the situation
Three elements may suggest that the chances are that this new approach will lead to an impasse, a waste of time and a destabilization of the governance of the Guadeloupe region.
The first element is the experience of the citizens’ climate convention. 150 citizens drawn by a lot full of goodwill who after more than nine (9) months of work made proposals full of common sense, but which did not go in the direction of power and were therefore rejected in the vast majority in the limbo of history (90%). This while not even give the French Parliament the opportunity to discuss these proposals. No one can deny that bottom-up is no longer working in the French Republic in particular since April 23, 2017. The choice to propose the establishment of Regional COPs is based on the same approach as the convention citizen for the climate: an up-bottom decision imposed and not previously discussed. Living conditions are still impacted by climate variations and the level of knowledge being the same when 2019, the chances that the proposals of the Regional COPs will be the same as those of the citizens’ climate convention are great. The proposals were not accepted in 2019, there is no reason for them to be accepted in 2024. Because even if they are declined at the regional level they will have consequences at the national level with a break with the capitalist system and trade at all costs.
The second element which suggests a waste of time is the proposed timetable and the very short deadlines. Proposing in less than six (6) months concrete, realistic and quantified ecological planning options for an archipelagic territory with so much missing information on the current and future climate is at best a sweet dream and at worst a lack of knowledge of the territory. The recurring lack of resources within public services has gradually led to a loss of skills, knowledge and capacity to act. The current situation with too partial knowledge of the territory and the inability to offer simulations on the economic, political and social consequences of decisions to reduce greenhouse gas emissions and protect biodiversity will push us to work by the rules of thumb. And therefore to return to the subject frequently to adjust what could not be planned or correctly evaluated. The Regional COP system already foresees annual updates.
The third element which suggests a destabilization of the region or even the country of Guadeloupe is the absence of peaceful social dialogue. Recent exchanges between the majorities of the Regional Council or the Departmental Council and civil society leave little optimism regarding the acceptance of common sense measures which would go against current policies but would better protect our environment and our living environment. As an example, the curious citizen can refer to the revisions of the Multi-year Energy Program (PPE) and the Regional Plan for Economic Development, Innovation and Internationalization (SRDEII).
Effective and realistic ecological planning can only be carried out through a disruption in our mode of operation leading to profound changes in the economy and political governance. The current political power does not seem disposed to too much evolution or even ecological revolution.
In conclusion
TCGNRG will participate in workshops to which we are granted access. This is not with the aim of seeking the best solutions at the regional level for planning but rather to ensure that this moment of democracy is not stolen from civil society using misused scientific concepts such as vague notions of green and renewable energies.
Solutions for a lucid and just transition already exist, we can cite among others the massive development of geothermal energy, free public transport, the reduction of meat consumption, the reduction of processed foods, the development of subsistence agriculture based on agroforestry and permaculture, the promotion of clothing styles more in line with our climate, the revision of taxation to promote the development of production and the local economy, the development of local police powers, etc.
These solutions are only rarely implemented, because they will cause a significant change in the functioning of society and the balance of power. The lobbies of the old carbon world are powerful and have no desire to lose their privileges, the results of the citizens’ climate convention are proof of this.

TCGNRG Comments on Guadeloupe PPE 2023-2033
The Multiannual Energy Programs (PPE in French) define the orientation and the methodology to be applied by territory to manage their energy production and consumption in a broad sense. They are declined differently from one geographically isolated region to another.
At the French level, the so-called continental metropolis PPE (excluding non-connected territories, Corsica and DROM-COM, therefore independent) includes sections relating[1] to:
- the security of the supply
- improving of energy efficiency and reducing energy consumption
- the development of the exploitation of renewable and recovered energies
- the balanced development of networks, storage, energy transformation and management of energy demand
- the clean mobility development strategy
- the preservation of consumer purchasing power and the competitiveness of energy prices
- the assessment of professional skills needs
Without predicting the provisions that will be taken by the Guadeloupe territory for the period 2023-2033 under the responsibility of Région Guadeloupe, one can expect to find these majors themes supplemented with the specific issues of a small tropical island territory without reservation of fossil fuels.
Guadeloupe’s PPE is currently being revised for the period 2023-2033. The public presentation on March 1st, 2023 made it possible to take stock of the preparation of this important document for the future supply of electrical and fossil energies in Guadeloupe. The document made available leaves you thinking [2]. A presentation in PowerPoint format does not in any way constitute a relevant working document. The schedule provides first the approval by the Regional Council in April 2023, followed by the validation of the General Directorate for Energy and Climate as well as by the French environmental authorities between the months of June and August 2023, then a public availability in October and the final adoption in November this year.
The small amount of information made available nevertheless makes it possible to list the weaknesses of the current vision of the PPE and the points to be worked on and to be strengthened urgently to avoid the catastrophe of the policies on energy and mobility imposed from Brussels and Paris and which do not seem adapted to the country of Guadeloupe.
The first question comes from the forecasts made on energy needs by 2040 with two scenarios that have a difference of 12% in 2028 and 24% in 2040. This difference indicates that according to the two hypotheses, the changes to meet Guadeloupe’s future energy needs could be of the order of a quarter of energy to be produced additionally. Finding the surfaces available to produce a quarter of additional energy is difficult on a small archipelagic territory like that of Guadeloupe where conflicts of use already exist between town planning, agriculture, the preservation of biodiversity and heritage, and protection of natural environments, sites and landscapes. Both models are based on two main parameters, the evolution of the population and the development of electric and plug-in hybrid vehicles.
We are not immune to a natural disaster that forces us to welcome 20 to 30,000 inhabitants from a neighbouring island. On the other hand, the imposed development of electric vehicles should not destabilize our electricity network. An adaptation of European measures must already be studied in order to avoid a social, economic and human disaster.
Tracks to explore
Only two existing endogenous resources are likely to meet the challenge of the need for energy with low environmental and climatic impact in the Guadeloupe archipelago: geothermal energy; and photovoltaic on all the roofs of buildings and individual houses. It is essential that these two mature sources of production be clearly put forward with support at different levels, training of actors and future actors, awareness of the population, and production and recycling of production tools, i.e. photovoltaic panels and geothermal power plants.
Wind energy
The proposals for revised objectives seem overestimated for all of the proposals, except for geothermal and solar photovoltaic. The recent conflicts around the extension of the Dadou farm at Petit-Canal show that the acceptance limit of the implementation of industrial-scale onshore wind farms in Guadeloupe has been reached. The proposed objectives are unrealistic and disconnected from the reality of the territory which cannot at the same time advocate the protection of biodiversity and develop a technology with a strong environmental impact.
Hydropower
Climate change (drying of the atmosphere in the tropical areas) and growing water needs for market gardening and tourism make water resources increasingly fragile and limit the annual production of hydropower. New means of production can be installed, but annual production is unlikely to increase. It is illusory to rely on this resource and to further alter the water cycle in Guadeloupe by installing new devices on the network of rivers and water reservoirs.
Biomass
The use of endogenous biomass for energy production is in direct conflict with the needs for (re)nourishment of the soil (mulching, compost) and the production of activated carbon, the needs of which are growing in a territory where a large part of water catchment areas are contaminated by Kepon, among other things. This implies that the 266 MW expected in 2033 will be of exogenous origin, they will negatively impact Guadeloupe’s carbon footprint and will not improve its energy independence.
Mobility and hydrogen
The current approach aims to make the Guadeloupe electricity network absorb a large part of the mobility needs. This approach is worrying given the high instability of the latter. The geographical distribution of the stable means of production (thermal and geothermal power plant) in the territory makes it very sensitive to natural risks, in particular flooding and marine submersion in the low and humid zone of Jarry.
Mobility, until recently was outside the electricity network, it would be wiser to design a network for recharging electric and hybrid vehicles that is autonomous and disconnected from the main network. The unveiled potential of hydrogen allows us to be confident in the strong growth of fuel cell mobility. This approach will prevent the establishment of monopolies and promote local solutions.
The role of the citizen
The good results of awareness campaigns on controlling consumption are proof of the importance of the citizen in solving the production-consumption equation. And not just as a player in controlling and reducing energy consumption. The conflict in Dadou at Petit-Canal around the installation of large wind turbines on agricultural land shows that no project can succeed without the acceptance of all. Participatory democracy tools must be put in place within the framework of this PPE so that the people of Guadeloupe can design their new ways of consuming, producing and moving around. These tools must include training, awareness, participation in studies and decision-making.
Concluding point
To conclude, it is surprising that the structure of the continental metropolitan PPE model does not already appear. Guadeloupe’s autonomous energy territory is not fully addressed. Only the forecasts of the values of the productive power are put forward with questions on the evaluation of the socio-economic impacts and future reflections on the organization of mobility. The effects on the environment, the carbon footprint, and the cost of energy and mobility do not seem to have been considered yet.
In the end, the voice of the people is missing, the will of Guadeloupeans, of citizens to create the energy of tomorrow. And this, with all the consequences in terms of pollution, space management, environment, development, innovation, risks and independence. I, therefore, call for a review of the calendar and the addition of a stage with an enlightened popular consultation.

Low-Pressure and Sahara Dust from 7/27 to 7/28
For the last two days, a low-pressure zone and a layer of sand (dust) from the Sahara have been interacting in a harmonious dance.
source : https://www.star.nesdis.noaa.gov/GOES/sector.php?sat=G16§or=taw
source : https://forecast.uoa.gr/en/forecast-maps/dust/north-atlantic
The Sahara dust limits the development of cloud structures in the low-pressure area and its convective movements, with progressive weathering visible on the animation. The depression favours the transport of the layer of dust towards North America.
The presence of Saharan dust in the atmosphere of the North Atlantic has many negative effects on health, in particular by reducing air quality with the presence of fine particles and bacteria. It also impacts the environment with a strong greenhouse effect which favours heat waves and drying of the air which modifies the frequency and the quantity of rainfall.
Conversely, the presence of particles modifies atmospheric dynamics, in particular cyclogenesis. In an atmosphere overloaded with sand, convection is limited or even stopped, cyclones have less favourable conditions to form.
The presence of large quantities of sand from the Sahara modifies our understanding of meteorology in the North Atlantic but also of the current and future climate. Years with large concentrations of Sahara dust disturb our perception of climate change.
July 26th International Day for the Conservation of the Mangrove Ecosystem
Mangroves and their ecosystem have an essential role in biodiversity, the renewal of fish stock, the preservation of coastline, the quality of coastal waters, and the attenuation of flood waves. This list is not exhaustive and is growing day by day.
Therefore, preserving these environments is essential for the quality of life of women and men in the coastal zone.
Their preservation is complicated because they most often occupy areas with high tourist, port or real estate value. Making a choice between financially profitable projects and spaces that cannot be monetized is not accessible using a neo-capitalist reading grid.
To ensure the maintenance of these spaces of abundance, life and culture, it is necessary to agree to place the life of a fish, a mollusc, a crustacean, and a bird on the same level as that of ‘a company.
