conservation

the preservation, protection and management of an environment which takes into account recreational and aesthetic needs, in addition to preserving as much as possible of the natural fauna and flora and allowing for the harvesting of natural resources and agriculture. This necessitates the sensible planning of what is taken from the environment in terms of the yield of plants, animals and materials, whilst at the same time maintaining as much natural habitat as possible, and thus the largest possible GENE POOL.
