Biodiversity is described by Ruth Patrick as, “the presence of a large number of species of animals and
plants…”(Patrick 15). In other words, biodiversity is the term for the measure of the variety of different
species that do exist still on our plant. These species can range from the simplest bacteria to the very
complex primates. Biodiversity can relate locally or globally. For example the Southern New England
forest contains 20 or 30 tree species while in the rainforest of Peru there are hundreds of species of
trees (Patrick 15). There are also further ways to view biodiversity and that is in levels. These levels can
be the “diversity of higher plants, number of species, or expressed as sheer weight (biomass)” (Patrick
15). Biodiversity is different is each part of the world. Not every part of the world contains the same
amount of creatures yet there are parts of the world that might contain similar amounts. These regions
of the world have similar weather patterns and therefore similar species will develop there but they are
not necessarily the same. One of the more important regions of the world that contain a large amount
of biodiversity is the tropical rainforest region. “The forests comprise roughly 7% of the dry land surface
of Earth and may hold more than 50% of all species” (Patrick 15). Yet us as humans do not know all of
the creatures and organisms that live on this planet at all. We only have discovered, in one way or
another, about 1.4 million species yet the number that is estimated is about 10-100 million (Patrick 15).

The unknown species that do exist on this world can have many and countless benefits to the human
race. A good example can be the rosy periwinkle, which is a plant found on the island of Madagascar,
helped cure the Hodgkin’s disease and lymphocytic leukemia. (E.O. Wilson 3). Another can be the
cyclosporin that was found in an obscure Norwegian fungus that is the foundation for the organ
transplant business (Wilson 3). There also exist countless other potential uses and numerous other
benefits that can be found in nature. The only problem is that we do not know even half of the amount
of life that exists on this planet and many of them are disappearing faster than we can discover.
