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).
Of all invertebrates, the insects are by far the most numerous. There are so many species of insects that scientists have yet to discover them all, let alone name or count them. Estimates of the total number of insect fall in the range of 1 to 30 million. The vertebrates represent the remaining 3% of all species and include species that are the most familiar to us: amphibians, reptiles, birds, fishes, mammals. The list below provides estimates of the number of species within various groups of animals.
