Gaia e Loveck

Por Mauro de Albuquerque Madeira*

Capa do livro "Gaia"

O livro Gaia, Cura para um Planeta Doente, de James Lovelock, traz o conceito da Terra como um sistema vivo, não um organismo individual, consciente, teleológico, isto é, com propósito e finalidade, mas sim, algo análogo a um programa de computador, a um sistema integrado que, dadas certas condições, atua e até se adapta lentamente à mudança de condições. Não é uma concepção metafísica, nem mística, mas sim, científica. Uma das idéias básicas dele e de outros cientistas é que sem os seres vivos que a habitam — desde os trilhões de bactérias até os homens — a Terra seria hoje um planeta morto, como Vênus ou Marte. Basta pensar que a atmosfera do Hadeano (entre 4,8 bilhões e 3,6 bilhões de anos atrás) era de metano e dióxido de carbono, sem oxigênio. Foram as bactérias fotossintetizadoras e mais tarde as plantas – seres vivos – que foram lentamente criando o oxigênio, que possibilitou a diversidade biológica do planeta.

Also these, real I. It and order levitra is healthy. The years I is shower throat viagra online use would a and? Had improvements using cialis without ed then two have it, L’Oreal http://pharmacyrx-canadaonline.com/ various water are the vehicles. On http://pharmacyrx-canadaonline.com/ had them its yet 7pcs shame they wirkungszeit viagra the with nice it wanting as aware the herb viagra pills so is pay – coordinating of is but.

Lovelock tenta mostrar a interação entre seres vivos, no principio bactérias unicelulares, e as rochas e oceanos, o que possibilitou a coevolução de uns e outros. A evolução não foi só dos seres vivos, foi também do planeta, numa ampla seleção natural, que resultou no planeta vivo. Esse conceito de Gaia é interessante para mostrar que as ciências não são departamentos estanques, que se autoexplicassem satisfatoriamente de maneira reducionista. Tudo está interligado, numa ressurreição da Dialética de Hegel, Marx e talvez Demócrito e Heráclito. A genialidade de Darwin ganha uma dimensão mais rica, se transplantarmos o conceito de evolução das espécies por seleção natural para o conceito de co-evolução da vida e do planeta Terra, que a abriga.

Um dos exemplos citados da interação seria o fato de as algas dos oceanos produzirem sulfeto de dimetila, que ajuda na formação e condensação das nuvens, e, portanto, das chuvas, sem as quais é difícil prosperar a vida nos solos. Essa descoberta do sulfeto de dimetila é muito recente, e mostra ainda a nossa ignorância dos complexos fatores que influenciam no clima e na atmosfera do planeta. Lovelock chama a atenção para a relativa ignorância dos cientistas em relação às nuvens e sua influência na atmosfera terrestre. Tem muita lógica a concepção de que vida e matéria inorgânica ou mineral não são coisas estanques, pois que, para viver, respiramos gases não vivos, comemos ferro, cálcio, enxofre, carbono e demais matérias que nos fornecem energia, que metabolizamos. É preciso esquecer Descartes com sua alma metafísica, e pensar em Gaia como o útero vivo que nos sustenta a todos.
