Los Objetivos de Desarrollo del Milenio (ODM) han sido
la herramienta más exitosa en la historia para luchar
contra la pobreza a nivel mundial.
Se han logrado avances significativos y sustanciales en
muchos de los objetivos, incluyendo el de reducir a la
mitad la cantidad de personas que viven en condiciones
de pobreza extrema y el porcentaje de personas sin
acceso sostenible a fuentes mejoradas de agua potable.
El porcentaje de habitantes de tugurios disminuyó
significativamente. Se han realizado notables avances
en la lucha contra el paludismo y la tuberculosis. Hubo
mejoras visibles en todas las áreas de la salud, así
como en la enseñanza primaria.

The air you breathe, the water you drink and the food you eat all rely on biodiversity, but right now it is in crisis – because of us. What does this mean for our future and can we stop it?

It is the variety of life on Earth, in all its forms and all its interactions. If that sounds bewilderingly broad, that’s because it is. Biodiversity is the most complex feature of our planet and it is the most vital. “Without biodiversity, there is no future for humanity,” says Prof David Macdonald, at Oxford University.

The term was coined in 1985 – a contraction of “biological diversity” – but the huge global biodiversity losses now becoming apparent represent a crisis equalling – or quite possibly surpassing – climate change.

More formally, biodiversity is comprised of several levels, starting with genes, then individual species, then communities of creatures and finally entire ecosystems, such as forests or coral reefs, where life interplays with the physical environment. These myriad interactions have made Earth habitable for billions of years.

A more philosophical way of viewing biodiversity is this: it represents the knowledge learned by evolving species over millions of years about how to survive through the vastly varying environmental conditions Earth has experienced. Seen like that, experts warn, humanity is currently “burning the library of life”.
