Food chains, also called food webs, food networks and/or trophic networks, describe the feeding relationships between species to another within an ecosystem. Organisms are connected to the organisms they consume by arrows representing the direction of biomass transfer. Typically a food chain or food web refers to a graph where only connections are recorded, and a food network or ecosystem network refers to a network where the connections are given weights representing the quantity of nutrients or energy being transferred.

Glaciers are melting, the ice caps disappearing into oceans, and sea levels are rising. Arctic peoples can't find food, while fresh water supplies in Asia and South America are disappearing. Why? Global warming. Environmentalists and the U.S. Pentagon are promoting the use of space solar power via microwaves -- as David Kagan wrote in Sunstroke.

It sounds like a fast-food grudge match: Taco Bell is taking on the homeland of its namesake by reopening for the first time in 15 years in Mexico. "It's like bringing ice to the Arctic," complained pop culture historian Carlos Monsivais.

Dude, Mexico ALREADY has a lot of tacos, and guess what Taco Bell serves? It serves MEXICAN food, or at least knockoffs thereof! It's like opening a Sukiyaki Sam's in Japan, or a Hunan Express in China. Why does Taco Bell even try to serve mockeries of Mexico's own food?? You might as well bring sand to the Mojave Desert, or ice to the Arctic!

In 1906 I went to the Arctic with the food tastes and beliefs of the average American. By 1918, after eleven years as an Eskimo among Eskimos, I had learned things which caused me to shed most of those beliefs.

Ever wonder why your low fat ice cream is oh-so-creamy? "In June, Unilever, the Anglo-Dutch conglomerate, applied to Britain’s Food Standards Agency for permission to use a new ingredient in its frozen desserts — a protein cloned from the blood of an eel-like Arctic Ocean fish, the ocean pout." Mmmmmmmm.
