Wild plant species have subsequently been used for medicinal purposes in prehistoric times. Animals may also play a role, in particular in the research. It is estimated that 250,000 species of plants known, investigated only 5,000 for possible medical applications. Industry: for example, textile fibres, wood for heat and coverages. Biodiversity can be a source of energy (such as biomass). Biodiversity encompasses also the largest reserve of biochemical compounds imaginable, due to the variety of metabolic adaptations of organisms.
Other industrial products we get now are oils, lubricants, perfumes, dyes, paper, waxes, rubber, latex, resins, poisons, Cork. Supplies from animal origin include wool, silk, skin, leather, oil and waxes. Animals can also be used as a transport. Tourism and Recreation: biodiversity is a source of cheap wealth for many areas, such as parks and forests where wild nature and animals are a source of beauty and joy for many people. Ecotourism, in particular, is growing outdoor recreational activity.
Likewise, a large part of our cultural heritage in different fields (gastronomic, educational, spiritual) is intimately linked to local or regional diversity and will probably remain so. To all this is added, as Wikipedia, indicates that biodiversity is not static: is a system in constant evolution, in each species as well as in each individual agency. A current species may have been initiated since one to four million years ago, and 99% of the species that have ever existed in the Earth have become extinct. Biodiversity is not distributed evenly on Earth. It is richer in the tropics, and as one approaches polar regions fewer species and larger populations are found. The flora and fauna vary depending on climate, altitude, soil and the presence of other species. original author and source of the article.
