Introduction Do we all know what biodiversity means? Well I think some of us do not know what biodiversity is, but it is important for us to know is the meaning of biodiversity. Biodiversity is the variety of life. Most of the people recognize biodiversity by species but biodiversity is more than just species. A species is a group of living organism that can interbreed for example white-tailed deer, blue whales, and bacteria that you cannot even see with your eyes. Species is only one part of biodiversity. Biodiversity can be studied on many levels and at the highest level you can look at all the different species in earth. Biodiversity occurs at multiple scales of ecological organization, from genes all the way up to the entire biosphere.…show more content…
(2002) Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food. Adequate nutrition, in turn, is the prime requirement for ensuring the normal development (both physical and mental) of children, as well as the continuing health and productivity of adults. Reciprocally, world food production has affected biodiversity significantly in the past, and continues to do so up to the present, through its use and modification of biotic resources—on land, in freshwater environments, and in the oceans. The imperative to produce and supply nutritious food for all humans, already numbering over six billion and projected to number eight or nine billion in the course of the 21st century, is certain to become ever more challenging. An equally vital necessity is to devise food production systems that protect and enhance natural ecosystems and their diverse biotic resources. Given the poverty and famine that prevail in many regions, and the foreseen change of the earth’s climate (which is inherently unstable in any case), it is an open question whether, and how, humanity can provide for itself while avoiding irreversible damage to natural ecosystems and their
