Times do and don't change
Skateboarding merit badge?Why not a Goth makeup merit badge?
Rise in scouting reported.
When they say they are seeking more “adult scout leaders” they must be thinking of “adults” as being anywhere from 22 to 29, wear their baseball caps backwards and have tattoos.
Bread, wine most ethical answer to water depletion
The concept of water footprints – or "virtual water" – will tell consumers the amount of precious H2O that has been used in the manufacture of products they buy. As with carbon footprints, a "virtual water" figure will indicate the extent to which a particular product has cost the earth. And, as with carbon footprints, the message is clear: less is better.

The results are striking. An apple weighing 100g has a water footprint of 70 litres, while a 125ml cup of coffee has a water footprint twice that size, 140 litres. But the water used in producing wheat or meat is much greater. A single kilogram of barley has a water footprint of 1,300 litres, while the industrial production of a kilogram of beef amasses a water footprint of 15,500 litres.
Poultry, meanwhile, has a smaller water footprint than red meat: producing a kilogram of chicken meat leaves a comparably much smaller water footprint of 3,900 litres.
Academics behind the "virtual water" calculations have also created a worldwide league table for the water footprint of different countries. The US is the biggest offender, with a water footprint of close to 2,500 cubic meters per year per capita, while Italy is a close second. Britain's water footprint is relatively modest at 1,245 cubic metres per year per capita.
The calculations are fiendishly complicated. But if they prove popular, calculations of water footprints could do much more to help minimise the environmental impact of consumption than other, similar schemes.
