When we humans mess with nature we are eventually the real losers. At our vacation home in Marathon, we have a huge problem with Green Iguana.
They have been released and have no predators...and while they eat insects, they also eat bird eggs and are decimating the bird population.
"Green Iguanas are eaten in Central America and Uromastyx in Africa and India. In North Africa, Uromastyx are considered dhaab or 'fish of the desert' and eaten by nomadic tribes.[4] In India too, these lizards are caught for their meat, about which Malcolm Smith says ..with certain castes of Hindoos it is a regular article of diet..the meat is said to be excellent and white like chicken...the head and feet are not eaten, but the tail is considered a great delicacy...the fat of the body is boiled down and the resulting oil is used as an embrocation and also as a cure for impotence."
Maybe that last phrase will start a run on Iguana!
