Plaidoyer pour les animaux

Science & Nature

Dans la lignée dePlaidoyer pour l'altruisme, Matthieu Ricard invite à étendre notre bienveillance à l'ensemble des êtres sensibles. Dans l'intérêt des animaux, mais aussi des hommes.Nous tuons chaque année 60 milliards d'animaux terrestres et 1 000 milliards d'animaux marins pour notre consommation. Un massacre inégalé dans l'histoire de l'Humanité qui pose un défi éthique majeur et nuit à nos sociétés : cette surconsommation aggrave la faim dans le monde, provoque des déséquilibres écologiques, est mauvaise pour notre santé.En plus de l'alimentation, nous instrumentalisons aussi les animaux pour des raisons purement vénales (trafic de la faune sauvage), pour la recherche scientifique ou par simple divertissement (corridas, cirques, zoos).Et si le temps était venu de les considérer non plus comme des êtres inférieurs mais comme nos "concitoyens" sur cette terre ?Nous vivons dans un monde interdépendant où le sort de chaque être, quel qu'il soit, est intimement lié à celui des autres. Il ne s'agit pas de s'occuper que des animaux mais aussi des animaux.Cet essai lumineux met à la portée de tous les connaissances actuelles sur les animaux, et sur la façon dont nous les traitons.Une invitation à changer nos comportements et nos mentalités.

Gaurile negre

Science & Nature

Introducere şi note de David Shukman Traducere de Alexandru Anghel „Una dintre cele mai strălucite minți științifice de la Einstein încoace." - Daily Express În 2016, Stephen Hawking a abordat în cadrul Prelegerilor Reith, BBC, un subiect care l-a fascinat întreaga viață – găurile negre. Faimosul fizician susține că dacă am reuși să înțelegem găurile negre și felul în care pun la încercare natura spațiului și timpului, am fi mai aproape de dezlegarea misterelor universului. Se spune că realitatea este uneori mai ciudată decât ficțiunea, ceea ce nicăieri nu este mai adevărat decât în cazul găurilor negre. Ele sunt mai ciudate decât orice și-au imaginat vreodată autorii de literatură științifico-fantastică.

Den genetiska dödsboken

Science & Nature

Ny bok om evolutionens underverk av författaren till Den själviska genen »En färgsprakande rundtur i naturen sedd ur genernas synvinkel.« Times väljer Den genetiska dödsboken till Årets vetenskapsbok 2024 »En magnifik bok om evolutionens underverk.« Philip Ball, Science En kamouflerad ödla har ett uttorkat landskap av sand och stenar »målat« på ryggen. Ödlans hud kan läsas som en beskrivning av en urtida öken, en värld där dess förfäder levde och överlevde. Sådana beskrivningar går dock djupare än huden. De tränger ända in i den levande varelsens grundstomme. Den genetiska dödsboken är en banbrytande bok: ett utforskande av den darwinistiska evolutionens makt och vad den kan avslöja om det förflutna. Richard Dawkins visar hur varje levande varelses kropp, beteende och gener kan läsas som en bok - ett arkiv över dess förfäders världar. I framtiden kommer en zoolog som ställs inför ett hittills okänt djur att kunna avkoda dess förfäders historia genom att läsa djurets unika »dödsbok«. Den genetiska dödsboken är rikt illustrerad i färg och öppnar porten till ett förflutet som är mer levande, nyanserat och fängslande än någonting vi tidigare sett. I översättning av Manne Svensson. RICHARD DAWKINS [f. 1941] är evolutionsbiolog, etolog, före detta professor vid Oxfords universitet och flerfaldigt prisbelönt författare. Med debuten Den själviska genen [1976] förändrade han helt synen evolutionsteorin och han har jämförts med tidigare revolutionära biologer som Charles Darwin, James Watson och Francis Crick.
