We are accustomed to thinking of military success as determined by quality of weaponry, rather than by food supply. But a
clear example of how improvements in food supply may decisively increase military success comes from the history of Maori New
Zealand. The Maori are the Polynesian people who were the first to settle New Zealand. Traditionally, they fought frequent fierce
wars against each other, but only against closely neighboring tribes. Those wars were limited by the modest productivity of their
agriculture, whose staple crop was sweet potatoes. It was not possible to grow enough sweet potatoes to feed an army in the field
for a long time or on distant marches. When Europeans arrived in New Zealand, they brought potatoes, which beginning around
1815 considerably increased Maori crop yields. Maori could now grow enough food to supply armies in the field for many weeks.
The result was a 15-year period in Maori history, from 1818 until 1833, when Maori tribes that had acquiredpotatoes and guns from
the English sent armies out on raids to attack tribes hundreds of miles away that had not yet acquired potatoes and guns. Thus, the
potato's productivity relieved previous limitations on Maori warfare, similar to the limitations that low-productivity corn agriculture
imposed on Maya warfare.

Lessons in using the internet safely are set to
become a compulsory part of the curriculum for
primary school children in England from 2011.
The lessons are one element of a new government
strategy being unveiled called "Click Clever, Click Safe".
Children will also be encouraged to follow an online
"Green Cross Code" and block and report inappropriate
content.
"We must ensure that this virtual world is safe for our
children just as we try to ensure that the real world is,"
said Prime Minister Gordon Brown at the launch of the
campaign.
"The internet is a wonderful and powerful tool that is
