With our passing, might some lost contribution of ours leave the planet a bit more impoverished? It is possible that, instead of heaving a huge biological sigh of relief, the world without us would miss us?

Arsenic turned out to work even better, and was cheaper. Until it was banned in the 1890s, it was used widely, and heavy arsenic levels are sometimes a problem for archaeologists examining some old U.S. graveyards. What they generally find is that the bodies decomposed anyway, but the arsenic stayed.

In the 1930s, with no computers to precisely calculate tolerances of construction materials, cautious engineers simply heaped on excess mass and redundancy. "We're living off the overcapacity of our forefathers.

pulsations that rock the planet.

Plastic is still plastic. The material still remains a polymer. Polyethylene is not biodegraded in any

And should biologic time run out and some plastics remain, there is always geologic time. "The upheavals and pressure will change it into something else. Just like trees buried in bogs a long time ago—the geologic process, not biodegradation, changed them into oil and coal. Maybe high concentrations of plastics will turn into something like that. Eventually, they will change. Change is the hallmark of nature. Nothing remains the same.

I think that people's nature is always to want a better life. So from that, we should not expect human beings to behave for benefit of the rest of nature-of the environment. You can only expect people to help the environment out of their own interest" Proffessor Zheng Zhe

Once, we built structures entirely from the most durable substances we knew: granite block, for instance. The results are still around today to admire, but we don't often emulate them, because quarrying, cutting, transporting, and fitting stone require a patience we no longer possess.

Los llaneros son reservados con la gente que acaban de conocer —le respondió el médico—. Ten paciencia.

That's the problem: Most people don't know where money comes from, nor how it's created." Which, he believes, is the reason why our economy today resembles a chain letter based on the fiction of an infinite number of recipients, instead of a terrarium—such as Terra, the Earth itself.

Al igual que nuestro pariente el chimpancé, siempre nos hemos matado unos a otros para disputarnos el territorio y las hembras, pero con el advenimiento de la esclavitud nos redujimos a nosotros mismos a algo nuevo: a un cultivo de exportación.

I'm so amazed," he says, "by the ability of life to hang on to anything. Given the opportunity, it goes everywhere. A species as creative and arguably intelligent as our own should somehow find a way to achieve a balance. We have a lot to learn, obviously. But I haven't given up on us.

He knew the terrible tales of sea otters choking on polyethylene rings from beer six-packs; of swans and gulls strangled by nylon nets and fishing lines; of a green sea turtle in Hawaii dead with a pocket comb, a foot of nylon rope, and a toy truck wheel lodged in its gut. His personal worst

Before artificial nitrogen fertilizer became widely available, the world's population was around 2 billion. When we no longer have it - or if we ever decide to stop using it - that may be the number to which our own naturally gravitates.

Este equilibrio entre humanos, flora y fauna empezó a tambalearse cuando los primeros se convirtieron ellos mismos en presa; o, mejor dicho, en mercancía.

Aunque ya han aparecido plásticos realmente biodegradables derivados de azúcares vegetales naturales, así como un poliéster igualmente biodegradable hecho a base de bacterias, las probabilidades de que estos reemplacen a los originales derivados del petróleo no son muchas.

Ha entrado en escena el Homo sedentarius. Ahora es el alimento el que migra hacia nosotros, junto con artículos de lujo y otros bienes de consumo que no existieron durante la mayor parte de la historia humana.
