The May 22 One Week article “Pros, cons of new school food rules” reminded me of a research project I did in graduate school in 1980. Over a 10-day period in the elementary school where I taught, I weighed the amount of waste in each of six food categories. Then, basing my calculations on average amounts of food thrown away, I projected not only the tons of food wasted nationally (both daily and yearly) but the cost as well. Federal regulations may have changed since then, but I imagine this problem of waste persists.

Regarding the May 29 Upfront column, “How we’re addressing your website concerns”: Excellent “remodeling.” Change is good – good change is even better! Thank you for all of the hard work that goes into the great news you disseminate.

Regarding the April 28 article “To colonize space, start closer to Earth” (CSMonitor.com): I have long felt that development toward a Mars mission would be better served by first industrializing, and making profitable, a larger and larger low-Earth-orbit presence, supported from Earth.
The real questions for us relate to the economic viability of development at the slow pace that will be forced by the large distances.
The costs of doing it fast from Earth are prohibitive. How long can we sustain an investment before there is some payback? But this pathway of slowly growing an off-Earth self-supporting human space residential/industrial ecosystem will likely be a faster path, and certainly a more meaningful and sustainable one, than trying to force an all-in-one shot to Mars, paid for by taxes, that risks lives, consumes astronomical financial resources, and establishes nothing.
