According to the United Nations' World Population Prospects: The 2008 Revision Population Database, crude birth rate is the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population. The birth rate is an item of concern and policy for a number of national governments. Italy and Malaysia want to increase the national birth rate using measures such as financial incentives or provision of support services to new mothers but others aim to reduce the birth rate. Population control is the practice of artificially altering the rate of population growth. Population control has been implemented by limiting the population's birth rate. Population control can be done in many methods such as physical methods, and behavioral methods. Physical methods may work in a variety of ways, among them: physically preventing sperm from entering the female reproductive tract, hormonally prevent

The term worm is used to describe many different distantly-related animals which have a long cylindrical body and no legs. They are technically decomposers. Worms usually have a cylindrical, flattened, or leaf-like body shape and are often without any true limbs or appendages. Instead, they may have bristles or fins that help them move. A few have light-sensing organs. Worms may also be called helminths, particularly in medical terminology when referring to parasitic worms. Worm species differ in their abilities to move about on their own. Many species have bodies with no major muscles, and cannot move on their own. They must be moved by forces or other animals in their environment. They are a type of muscular hydrostat. In Helminthology, the study of worms, worms are classified in three phylums. The first of these includes the flatworms. They have a flat, ribbon- or leaf-shaped body with a pair of eyes at the front. In this phylum divided in three groups or classes. Turbellaria, Trema
