Terres Arables

A l’échelle humaine, le sol cultivable a une durée de vie limitée car créer ne serait-ce qu’une fine couche de terre arable prend des millénaires.

Par inadvertance, nous épuisons cette précieuse ressource et nous ne disposons d’aucune solution technique viable pour la remplacer à une échelle de temps satisfaisante.

La plupart des aliments sont cultivés sur ces terres – dans la mince couche de sol recouvrant les roches sédimentaires.

Au rythme des pertes provoquées par

l’agriculture intensive, la pollution, le développement

de l’industrie et de l’urbanisation, on estime que
nous manquerons de terres cultivables d’ici soixante ans.

L’absence de sols arables entraînant la raréfaction de la

raréfaction de la vie végétale, il est difficile de

concevoir qu’une vie animale puisse se maintenir.
Pas de sol, pas de vie.
