Thomas MalthusWhere there are few people, and a great quantity of fertile land, the power of the earth to afford a yearly increase of food may be compared to a great reservoir of water, supplied by a moderate stream.

But the sooner, undoubtedly, will the reservoir be exhausted, and the streams only remain.
