Conservation

A conservator at work

Conservation refers to the preservation, restoration or repair of the natural environment, wildlife, or archaeological, historical, and cultural sites and artifacts.[1]

On the environment see Conservation and environmentalism.

Conservation projects aim to:

* maintain the environment and natural resources for future generations,
* maintain species diversity for our benefit and that of wildlife,
* provide opportunities for education and the enjoyment of the environment.

## Fishing[edit]

Fishermen (or their governments) often agree to leave a certain number of fish uncaught, so that the population can replenish itself. If fisheries are fished beyond their natural capacity, the fish population may collapse and fail to replenish itself quickly enough for the fishery to remain economically viable. This phenomenon is known as overfishing.
