This power is highly concentrated in herbs and spices; just half a teaspoon of ground cinnamon has as many antioxidants as half a cup of blueberries, and half a teaspoon of dried oregano has the antioxidant power of three cups of raw spinach.[1]
Some Rough Estimates of Species Numbers. The estimated number of animals on our planet falls somewhere in the vast range of 3-30 million species (Erwin 1983, Wolosz 1988).
There are some 15,000 species of protozoans, or one-celled animals, but the record for the number of different species is held by insects, with well over 750,000! The best estimate is that there are at least three million different kinds of animals on earth!
