Researchers at UC Davis warn there are major environmental downsides to lab-grown meat. According to their “cradle-to-gate life cycle” analysis, the lab-grown meat industry produces up to 25 times more CO2 than traditional animal husbandry, which nullifies the core ideological foundation upon which the industry is built. Each kilo of cultured meat produces anywhere from 542 pounds (246 kilos) to 3,325 pounds (1,508 kg) of carbon dioxide emissions, making the climate impact of cultured meat four to 25 times greater than that of conventional beef

Les offensés professionnels
Partant du principe fort confortable que tout ce qui n’est pas comme moi m’opprime, le réel lui-même devient oppressif. La rhétorique fonctionne admirablement : le refus de l’altérité se fonde sur une morale biaisée mais irréfutable (au sens de Popper).

100% de voitures neuves électriques en 2035 : "c'est tenable, mais à quel prix ?"
100% des voitures vendues en France en 2035 seront électriques ou hybrides : c'est ce qu'assure Emmanuel Macron ce lundi matin dans une interview aux "Echos", à l'occasion de l'ouverture du Mondial de l'Auto à Paris. Cet objectif "est tenable, mais à quel prix ?" s'interroge François-Xavier Pietri, journaliste spécialisé. Aujourd'hui, 20% des nouvelles voitures sont électriques.

Models Hide the Shortcomings of Wind and Solar
One of the broader issues omitted is the fact that the electrical output of wind turbines and solar panels does not match up well with the timing needs of society, leading to the need for a great deal of energy storage. Another omitted issue is the huge quantity of energy products and other materials required to make a transition to a mostly electrical economy. It is easy to see that both omitted issues would add a huge amount of energy costs and other costs, if a major transition is made. Furthermore, wind and solar have gotten along so far using hidden subsidies from the fossil fuel energy system, including the subsidy of being allowed to go first on the electricity grid. EROEI calculations cannot evaluate the amount of this hidden subsidy.
