From J
Laura Spinney made a good case for the promotion of breadfruit as a food staple, but there is yet another advantage to the plant that was not discussed (28 June, p 40).
Much of agriculture involves the continuous tilling of the soil, with the attendant risk of erosion. A food-bearing tree, on the other hand, is the ideal thing to anchor and conserve soil.
That is a double dose of good fortune that any country would welcome.
