According to a national Vegetarian Resource Group Poll conducted by Harris Interactive, nearly 15 percent of Americans say they never eat fish or seafood.

The pacific sardine lives along the coasts of North America from Alaska to southern California. Sardines, once a major part of the California fishing industry, are now considered to be "commercially extinct." Another species classified as "commercially extinct" is the New England haddock. Ecologists have also been concerned about the significant reduction in finfish, the Atlantic bluefin tuna, Lake Erie cisco, and blackfins that inhabit Lakes Huron and Michigan

Over 200,000 porpoises are killed every year by fishermen seeking tuna in the Pacific. Sea turtles are similarly killed in Caribbean shrimp operations.

There are signs that the fishing industry (which is quite energy-intensive) has already overfished the oceans in several areas. And fish could never play a major role in the worlds diet anyway: the entire global fish catch of the world, if divided among all the world's inhabitants would amount to only a few ounces of fish per person per week.

The American Dietetic Association reports that throughout history, the human race has lived on "vegetarian or near vegetarian diets," and meat has traditionally been a luxury. Studies show the healthiest human populations on the globe live almost entirely on plant foods--useful data, given our skyrocketing healthcare costs. Nathan Pritikin, author of The Pritikin Plan, recommended not more than three ounces of animal protein per day; three ounces per week for his patients who had already suffered a heart attack.

Obviously, then, the idea of providing the entire world with a Western diet is quite absurd. But what about satisfying today's demand for meat--which provides only a fraction of the population with a Western-style diet? If the world population triples in the next 100 years, then meat production would have to triple as well. Instead of 3.7 billion acres of cropland and 7.5 billion acres of grazing land, we would require 11.1 billion acres of cropland and 22.5 billion acres of grazing land.

But this is slightly larger than the total land area of the six inhabited continents! We are desperately short of forests, water and energy already. Even if we resort to extreme methods of population control: abortion, infanticide, genocide, etc...modest increases in the world population during the next generation would make it impossible to maintain current levels of meat consumption. On a vegetarian diet, however, the world could easily support a population several times its present size.
