BETTER THAN BEEF? This smorgasbord offers ant pupae and yellow bamboo caterpillars around a pile of ordinary scrambled eggs. Meyer-Rochow photographed this platter of appetizers during his foreign travels. He and other researchers have shown such bugs to be nutritious. Many researchers argue that their harvesting can also be better for the environment than is the production of conventional meat animals. Meyer-Rochow |
"Can Meat and Fish Consumption Be Sustainable?" That’s the provocative title of a press release just sent to us by the Worldwatch Institute, a small but venerable think tank that focuses on natural resource issues.
It’s also the theme of a chapter in Worldwatch’s 2008 State of the World report, its 25th annual book-length analysis of resource trends and economics. Here, its analysts take on the substantial—and often hidden—costs of producing animal protein to satisfy human hunger.
In 2006, "farmers produced an estimated 276 million tons of chicken, pork, beef, and other meat—four times as much as in 1961," Worldwatch has just reported. As for fish, some 140 million tons were hauled in globally during 2005, the most recent year for which data are available. "That was eight times as much as in 1950," note Brian Halweil and Danielle Nierenberg, the chapter’s authors.
Part of the growth in production reflects a growing demand, fueled by world population and increasing wealth that allows increased consumption of animal protein, even within formerly impoverished nations. For meat, it has doubled over the past 45 years; fish consumption quadrupled over a 55-year span.
