Birds, Jim Robbins posits, are our most vital connection to nature. They compel us to look to the skies, both literally and metaphorically, draw us out into nature to seek their beauty, and let us experience vicariously what it is like to be weightless.

Somos um país urbano: 84% da população brasileira concentra-se em cidades e ao menos metade vive em municípios com mais de 100 mil habitantes. Mas a vida urbana não traz apenas novas oportunidades. Ela propicia doenças provocadas por falta de saneamento, picadas de mosquitos, poluição, violência, ritmo frenético... E tudo isso não ocorre mais apenas nas grandes cidades, mas também nas médias e mesmo pequenas, quase sempre negligenciadas pelo poder público e pelos próprios cidadãos.

Climate models show that global crop production will decline every decade for the rest of this century due to drought, heat, and flooding. Water supplies are in jeopardy. Meanwhile, the world’s population is expected to grow another 30 percent by midcentury. So how, really, will we feed nine billion people sustainably in the coming decades? Amanda Little, a professor at Vanderbilt University and an award-winning journalist, spent three years traveling through a dozen countries and as many US states in search of answers to this question.

One of the great science and health revelations of our time is the danger posed by meat-eating. Every day, it seems, we are warned about the harm producing and consuming meat can do to the environment and our bodies.
