The principle aim of conservation is to ensure the survival of life in all its forms and variety, and to make certain that natural resources are not used beyond their capacity for renewal but continue for the benefit of future generations. Conservation requires an understanding of ecology and the interrelationships of the different plants and animals (including our own species)with each other and with their environment.
Concern for the health of the environment is steadily increasing as can be seen from the growth of conservation organisations in almost every continent.
Ever increasing human populations lead to an increase of the demand for natural resources. This has many effects including deforestation, habitat loss, pollution of air and water etc. Poaching of animals for meat, fur and the medicine trade also reduces animal numbers. Conservation is an active means of slowing down or reversing these trends in an attempt to safeguard the environment and all living things within it.
