En la situación presente, la causa principal de la llamada sexta extinción (Leakey & Lewin, 1997) es la expansión e incremento en biomasa de una especie en particular -los humanos-a costa de las demás. Haciendo uso de la tecnología aparejada a su evolución cultural, nuestra especie viene compitiendo por terreno y recursos con éxito, a la vez que introduce cantidades significativas de energía adicional en los sistemas naturales. Como consecuencia, los ecosistemas se rejuvenecen, se simplifican, y pierden biodiversidad.
