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).
Current estimates of the total number of species on Earth range from 5 to 30 million, of which, the 2005 Millennium Ecosystem Assessment notes approximately 2 million have been formally described. Determining an accurate count is a challenging job because there is no central registry for species.
