      • The Nut is used for many different things ranging from polishing to cooking.

      • As is shown above in 2000/01 the U.S. Walnut industry had to increase the price by 37%.
      • It is thought the price rise was due to the price of exporting the product.
  • 8.
      • There are many species of walnut tree, only the English Walnut (Juglans nigra) grows in England.
      • The climate in England is not sufficiently warm enough to grow in large plantations.
      • Good quality walnut oil can only be made from French walnut trees.
      • Not enough walnut could be grown in England to meet the entire English demand.
      • The trees are grown in groves so no deforestation takes place (voiced opinions by Scierie-Forest Walnut exploiters France).
  • 9.
      • The Gun trade is enhanced by readily available amounts of walnut for the gun stocks.
      • Gallons of fuel is being used to ship unnecessary amounts of walnut around the world to simply be wasted. (As protested by Christopher Kendall from the university of north Carolina)
      • Walnuts are not essential to our survival.
      • Less squirrels would be shot in plantations for stealing nuts.
