Population control

 Population control is the practice of artificially maintaining the size of any population. It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology. Factors influencing population control Population control may involve culling   , or manipulation of the reproductive capability. The growth of a population may be limited by environmental factors such as food supply or predation. * Food – both the quantity and the quality of food are important. The population growth and decline of species depends on the amount of their food availability. The more available food, the more the population grows to meet it. The less nutritious food, the less fertile a species of reproductive age becomes. * Predators – as a prey population becomes larger, it becomes easier for predators to find prey. If the number of predato...
