Green iguana in captivity
The Green Iguana (''Iguana iguana'') has become popular in the pet trade – over 800,000 animals were imported into the United States alone during 1995, primarily originating from captive farming operations based in their native countries (Honduras, El Salvador, Colombia, and Panama). In 1998 a National Iguana Awareness Day (NIAD) was established to discourage consumers from viewing iguanas as "disposable pets". Despite the low cost and "mass market" appeal of these animals they are demanding to care for properly over the course of their lifetimes. More often than not, diet, lighting, and other housing conditions for green iguana are inadequate (in a major way) causing 70% of green iguanas in captivity to die within their first year of life.〔
==Size==
People purchase iguanas due to the small size, low price, and apparent low cost of feeding of juvenile iguanas. Though small as juveniles, iguanas can grow to 4 feet in length and weigh some 20 pounds An iguana will not grow properly without a UVB light source. The UVB is necessary because captive iguanas do not get natural sunlight and this UVB allows the iguana make vitamin D3. The purpose of vitamin D3 is to digest calcium. Without being able to digest calcium, the iguana develops Metabolic Bone Disease (MBD). Metabolic Bone Disease causes soft bones, stunted growth, permanent bone deformities, frequent broken bones, loss of limbs and ultimately, death"
