What is Castration and give me the types of castration​

Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles. Castration may be accomplished by physical, chemical or hormonal techniques. Testicles may be removed surgically or killed by obstructing the blood supply. Young calves may be castrated with rubber rings.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
