Abstract

During wartime it is easy to forget dangers which, in the long-term, scheme of things, are even more pressing than many of the problems now absorbing world-wide attention, Such a menace is soil erosion, which, in cold fact, is the master-danger that feces posterity. Since, in the last resort soil erosion, even on the grandest scale. has been wholly the fault of man. its continuation will be equally the fault of man. Man's attitude towards this problem is the supreme test of his wisdom and of his real interest in the species he represents. Remedial measures against the results of soil erosion, where still possible must be exceedingly slow in their operation, while preventive measures not only demand foresight, but benefits must necess rily be cumulative and spread over generations-nay, centuries.
