Cambio Climático

¿Se imaginan 6 mil millones de personas consumiendo en el mundo al mismo tiempo?. Somos 6 mil millones que necesitamos, alimento, agua, energía, vestimenta, trabajo; y a eso hay que sumarle el deseo de comprar aquellas cosas que nos gustan. Somos 6 mil millones de personas consumiendo lo que la Tierra produce. Sin embargo, ¿sabemos si la Tierra puede producir todo lo que nosotros necesitamos?

La “Huella Ecológica” es el indicador que nos permite medir la superficie necesaria para proveer de recursos a las personas. Es decir, es el indicador que nos permite saber si es que la Tierra puede producir y regenerarse de acuerdo a nuestro ritmo de consumo.

 

YA ESTAMOS DEBIENDO

Actualmente ya estamos consumiendo 20% más de lo que la Tierra nos puede brindar. Estamos extrayendo de ella una cantidad tan enorme de recursos, que cada vez su capacidad de recuperación es menor. Si continuamos con ese ritmo, no tendremos que esperar mucho para que nuestra calidad de vida empeore aún más.

Según un informe de la WWF (World Wide Foundation), dentro de 30 años el planeta tendrá serios problemas para reponer los recursos naturales que el hombre necesita para su subsistencia.

Las cifras del informe de la WWF estiman que para el 2050, si es que no tomamos las medidas necesarias y continuamos con este ritmo desquiciado, estaremos consumiendo entre un 180 a 200% más de lo que nuestra bondadosa casa azul consigue producir.

En 1999 el consumo promedio en África o Asia era menos de 1,4 hectareas por persona, la huella promedio del europeo occidental era alrededor de 5 ha y la del norteamericano promedio de 9.6 ha. Si todos consumieran recursos naturales y emitieran dióxido de carbono (CO2) al ritmo que lo hacen los ciudadanos de los países desarrollados, se precisarían al menos otras dos Tierras para atender las necesidades.

“LA CUENTA POR FAVOR”

Según el Dr. Claude Martin, director general del WWF Internacional."Vivimos en un planeta generoso, pero tiene límites." La lista de recursos naturales no renovables está aumentando cada año. La Tierra es un planeta finito, seguir explotándolo y contaminándolo a los niveles actuales tiene un potencial de sustentabilidad igual a cero.

El Índice del Planeta Viviente, que se basa en las tendencias de las poblaciones de cientos de especies de aves, mamíferos, reptiles, anfibios y peces, indica claramente que la actual presión del consumo humano no es sostenible.

Algunas cifras alarmantes: las especies de agua dulce se han reducido, en un promedio del 54 % de declinación en las poblaciones de 195 especies que habitan en ríos y ecosistemas de humedales. Las especies marinas también se encuentran amenazadas, con un promedio de declinación del 35 % en 217 especies. Asimismo, las poblaciones de especies forestales muestran una reducción del 15 % en 262 especies.

Esta situación debe revertirse. Para esto, tanto los Estados como la sociedad civil deben trabajar en conjunto y comprometerse con el cambio. Hacer que nuestro mundo sea sostenible es tarea de todos.
