Sostenibilidad
Attempts to put a dollar value on the natural world – so-called “natural capital” or “ecosystem services” – have produced some frankly staggering numbers. A seminal 1997 paper valued the world’s ecosystem services at US$33 trillion a year. This estimate was controversial, given that it dwarfed the entire global market economy, which at the time stood at roughly US$18 trillion a year.
Simplicidad
La principal ventaja de los vehículos eléctricos sobre los tradicionales es la simplicidad del motor eléctrico.
Aún recuerdo una evaluación medioambiental de la respetada Unión de Científicos Sensibilizados (UCS, por sus siglas en inglés) que leí en los años 80.
Until recently, if I were asked to imagine ship-breaking operations, I would automatically think of one of those documentaries where skinny barefoot children crawl around inside beached and broken ships, pulling and cutting off the salvageable material, including scrap metal for recycling. For their efforts they receive only pennies plus a host of injuries and ailments. The leftovers, many dangerous and toxic, are often discarded with little regard for human safety and the environment.
In Latin America, 13 million child laborers can be found selling goods alongside the roads, working beside their parents on farms, as domestic workers in homes, and doing hard labor in hazardous industries. Globally, however, the number of children involved in child labor has declined by one third since 2000, from 246 million to 168 million children.
A few weeks ago, I represented the Biodiversity and Ecosystem Services (BIO) Program at the first Natural Capital Summit in Stockholm. While the meeting’s attendants were few, they were strategically selected and the event is likely to have a significant impact on the future agenda of a community working to incorporate natural capital into development decisions.
