Semana del 6/6/10

Querido DiálogoEcológico: EEUU fue azotado por varias tormentas mayores este invierno pasado. Los informes sobre el tiempo local nunca mencionaron esta anomalía. ¿Pero es un signo del calentamiento climático?

Querido DiálogoEcológico: He estado oyendo mucho acerca de la popularidad de la leche vendida en bolsas (en comparación con cartones de plástico o cartón) en India, Europa y Canadá. ¿Cuáles son las ventajas ambientales para la leche en bolsas, y creen Uds. que se popularizará en EEUU? ¿Y qué otras opciones existen ahí para bebedores de leche que tratan de ser "verdes"?

I’ve been hearing about the popularity of milk sold in bags

Plastic milk bags are popular in many parts of Europe, Latin America and India and are catching on in Canada, South Africa and China. They use 75 percent less plastic than similar capacity plastic jugs, are made of easily recycled high-density polyethylene

Consuming Chemicals

What do breast milk, food cans, microwave popcorn, and fast-food French fry boxes have in common with meat, fish and dairy products? They’re all avenues of human ingestion of potentially harmful chemicals associated with everyday plastics.

Querido DiálogoEcológico: ¿Pueden usarse los aviones con combustibles más limpios o a base de electricidad? ¿Se ve cambios en el negocio de las aerolíneas para encontrar combustibles más limpios?

Can airplanes be run on cleaner fuels or be electric powered?

Given air travel’s huge contribution to our collective carbon footprint—flying accounts for about three percent of carbon emissions worldwide by some estimates—and the fact that basic passenger and cargo jet designs haven’t changed significantly in decades, the world is certainly ready for greener forms of flying.
