How to Double Global Food Production by 2050 and Reduce Environmental Damage

Cabo Pulmo, la perla del Golfo de California

National Geographic, Mayo 2011 Jacques Cousteau llamó al Golfo de California “el acuario del mundo”. Por Octavio Aburto y Enric Sala / Fotografías de Octavio Aburto En ese mar en los últimos 15 años, no comprendíamos qué había impresionado tanto al famoso explorador francés. Sí, habíamos visto cachalotes, delfines, lobos marinos en abundancia, pero cuando nos sumergíamos con nuestros tanques de buceo no teníamos la impresión de estar dentro de ningún acuario. Las historias sobre enormes meros y tiburones nos parecían cuentos de hadas. Las descripciones de los antiguos bancos[...]
